As a result of human activity, raw sewage, large amounts of nutrients like nitrogen, phosphorus and hydrocarbons are introduced into the water. These, in turn, allow harmful bacteria like E.coli, viruses, algae and insects to breed. The Scavenger VesselTM is the most effective pollution control and water maintenance vessel available in the world today. It was designed by U.S. based Water Management TechnologiesTM to clean and rejuvenate waterways "In Situ" such as lakes, rivers, harbors, and industrial waste water in order to promote healthy and safe environments. The Scavenger VesselTM with its Patented OxyPlusTM decontamination system improves water quality by reducing and eliminating bacteria and viruses, raising D.O. (Dissolved Oxygen) levels, controlling algae growth, improving water clarity and eliminating odors. A multi -purpose vessel, the Scavenger VesselrM not only decontaminates and re -oxygenates water; its unique design also allows it to collect floating debris simultaneously, creating safe, healthy and more attractive public waterways. The Scavenger Vessels OxyPlusTM Decontamination system has the following BENEFITS: IMPAIRED WATERS • High bacteria levels • Low Dissolved Oxygen Levels • Elevated BOD or COD levels • Unbalanced nutrients • High algae count AREAS OF IMPACT • Waterways / Canals • Rivers • Lakes • Ports • Harbors • Agricultural reservoirs BIOLOGICAL • Kills bacteria, parasites and microbes • Destroys fecal coliforms • Neutralizes viruses • Raises DO levels in water • Improves water quality overall PHYSICAL • Improves water clarity by reducing turbidity and removing color • Eliminates odors caused by sulfur, nitrogen, and organic materials • Controls algae growth by removing algae food sources • Eliminate the plume of nutrients left by surface debris removal o,. CHEMICAL • Reduces BOD and COD • Oxidizes some pesticides, insecticides herbicides and fungicides that are washed into the watershed OUR CUSTOMERS • Government agencies • Municipalities • Private Industries • Environmental Restoration entities • Agriculture l How It Works The key to the Scavenger Vessel is the advanced Patented OxyPlusT5 water decontamination system that treats and revitalizes waterways by aerating the water with a combination of ozone and oxygen. In full operation mode, the vessel scoops up floating debris, destroys bacteria, and injects life -supporting oxygen in the water. This process restores the overall health in the woter. The Scavenger Vessel in operation mode can decontaminate at a rate of up to 20,000 gallons of water per minute and inject up to 600,000 liters of oxygen per hour. DEFLECTOR Aids in maneuvering the boat. It can also deflect oxygen/water deep into the water bodies CLEANING THE WATER How the Scavenger Vessel's onboard OxyPlusT water treatment system works: WATER CANNON Can be used for dispensing agents/seawall cleanup CREW CABIN / 1 , , 000R to the , decontamination ® / w i41t chamber Ir OXYGENATED and clean water ODecontaminated crater exits through the hack or the boat anr' is oxygenated TRASH BIN 7 cubic yards OPEN BOW/BALLAST — TRASH Ballast is added to BASKET lower bow to scoop up trash OWater then enter.

When oxygen is injected into polluted water, the enrichment contributes directly to reducing contaminants suspended in the water. With the addition of ozone to the aeration process a very powerful yet environmentally safe disinfection occurs in the body of water being treated by the Scavenger Vessel'''. Ozone has been applied with great success in municipal sewer treatment processes worldwide because of its ability to disinfect water without leaving the harmful by-products leh by chlorine. In fact, ozone has been found to be more than 100 times more powerful than chlorine in destroying E.coli bacteria. As water enters through the bow of the vessel, the OxyPlusTM generates ozone and oxygen and injects it into the water. The ozone's life expectancy varies between a few seconds and a few minutes. The ozone then converts into oxygen. This process supports Chemical Oxygen Demand (COD), breaks down substances so that they become digestible to bacteria, and supports the aerobic oxidation of toxic nitrogen compounds. By altering the surface charge, ozone enables suspended particles to coagulate and be easily removed. In addition to algae and improving water clarity, ozone effectively oxidizes some pesticides and some algae therefore improving water clarity. Lastly, it increases the dissolved oxygen content in the water, which has a rejuvenating effect. The Scavenger Vessel's decontamination rate is 1.2 million gallons of water per hour with an hourly oxygen injection rate of up to 600,000 liters. This increases the dissolved oxygen levels in the water, and reduces the number of toxins in the water. Nova Southeastern University's Oceanographic Center says: "The Scavenger vessel's OxyPlusTM technology can significantly improve water quality. A single pass through the vessel's systems can reduce up to 98% of bacteria and coliform in the water, and reduce algae counts by half". RIVER WATER Before and after water samples treated with our OxyPIusTM System. lts """7"` nirONl4MINPlIGN VESSEL Debris Collector The Scavenger Vessel features a retractable stainless steel trash basket, which is mounted on the front of the vessel. It picks up debris floating on the surface of the water, up to o depth of 2.5 ft. The basket's design, which resembles a comb or grate, is engineered to virtually eliminate any water turbulence during the suction operation. The weight capacity of this basket is approximately 2,500 lbs. The basket is emptied into a containment bin by means of a hydraulic system, which is operated from the main cabin. Continuous debris collection is ensured by a secondary grill that is automatically activated to keep debris from entering the channel while the basket is being emptied into the bin. The containment bin has a capacity of 7 cubic yards and con effectively be emptied due to its bottom double folding doors activated by a lever. PICKING UP THE TRASH As trash and water are funneled into the bow, a basket catches the debris and empties it into a large on -board containment bin. WATER IS FUNNELED INTO THE BOW Vacuum water flow up to 20,000 gpm. Vacuum effect. The vessel does not have to run after debris. Water Cannon The multipurpose water cannon on the Scavenger Vessel Can: • Clean hard -to -reach areas, seawalls, or rocky shorelines; • Be used as a dispenser for dispersing agents • Fight Fires • Be used as an auxiliary means of propulsion Powered by an independent marine diesel engine, the water cannon is capable of developing a flow of 1250 gallons of water per minute, at a pressure of 100 psi. Effective Maneuverability The Scavenger Vessel can make a 360-degree turn, in place, with the bow open and in recuperation mode. This maneuver can be done without interrupting the decontamination process, using the special rear deflector that is attached to the stern of the vessel. The Scavenger Vessel never has to interrupt its recovery systems. Transport The Scavenger Vessel can be easily transported anywhere in the world.

No. 10/930,688 filed Aug. 31, 2004, now U.S. Pat. No. 7,517,459, which is a regular patent application based upon and claiming priority of provisional patent application 60/588,198 filed Jul. 15, 2004, the contents of both of which are incorporated herein by reference thereto. The present invention relates to a waterborne vessel with an oxygenation system which decontaminates surrounding water and a method therefore. BACKGROUND OF THE INVENTION Ozone (03) is one of the strongest oxidizing agents that is readily available. It is known to eliminate organic waste, reduce odor and reduce total organic carbon in water. Ozone is created in a number of different ways, including ultraviolet (UV) light, and corona discharge of electrical current through a stream of air or other gazes oxygen stream, among others. Ozone is formed when energy is applied to oxygen gas (03). The bonds that hold oxygen together are broken and three 25 oxygen molecules are combined to form two ozone mol- ecules. The ozone breaks down fairly quickly and as it does so it reverts back to pure oxygen, that is, an 02 molecule. The bonds that hold the oxygen atoms together are very weak which is why ozone acts as a strong oxidant. In addition, it is known that hydroxyl radicals OH also act as a purification gas. Hydroxyl radicals are formed when ozone, ultraviolet radiation and moisture are combined. Hydroxyl radicals are more powerful oxidants than ozone. Both ozone and hydroxyl radical gas breakdown over a short period of time (about 8-15 minutes) into oxygen. Hydroxyl radical gas is a condition in the fluid or gaseous mixture. Some bodies of water have become saturated with high levels of natural or man made materials which have a high biological oxygen demand and which in turn have created an eutrophic or anaerobic environment. It would be beneficial to clean these waters utilizing the various types of ozone and hydroxyl radical gases. 5 10 15 OBJECTS OF THE INVENTION 20 30 35 40 45 It is an object of the present invention to provide a water- borne vessel with an oxygenation system and a method to decontaminate surrounding water. 50 It is a further object of the present invention to provide an oxygenation system on a waterborne vessel and a method of decontamination wherein ozone and/or hydroxyl radical gas is injected, mixed and super saturated with a flow of water through the waterborne vessel. 55 It is an additional object of the present invention to provide a super saturization channel which significantly increases the amount of time the ozone and/or hydroxyl radical gas mixes in a certain flow volume of water thereby oxygenating the water and decontaminating that defined volume of flowing 60 water prior to further mixing with other water subject to additional oxygenation in the waterborne vessel. It is an additional object of the present invention to provide a mixing manifold to mix the ozone independent with respect to the hydroxyl radical gas and independent with respect to 65 atmospheric oxygen and wherein the resulting oxygenated water mixtures are independently fed into a confined water 2 bound space in the waterbome vessel to oxygenate a volume of water flowing through that confined space. SUMMARY OF THE INVENTION The waterborne vessel, in one embodiment, utilizes an underwater tunnel through which passes flowing water, an ozone gas generator, an ozone plus hydroxyl radical gas gen- eratorand a source of atmospheric oxygen. A manifold mixer mixes pressurized water independently with the ozone, the ozone plus hydroxyl radical gas and the atmospheric oxygen to produce corresponding oxygenated water mixtures. Each of these oxygenated water mixtures are fed via a conduit system into the confined flow of water passing through the tunnel. A diversion channel with reverse flow channel permits super saturation of diverted flow from the primary underwater tunnel channel to provide super saturated oxygenated water with ozone plus hydroxyl radical gases and atmospheric oxy- gen water mixtures. A decontamination method is also pro- vided.

FIG. 1 diagrammatically illustrates waterborne vessel 10 having an oxygenation system 12 disposed in an underwater tunnel 14 beneath the waterline of vessel 10. In general, water flow is established through tunnel 14 based upon the opened/ 15 closed position of gills 16 and the operation of the propeller at propeller region 18. Tunnel 14 is sometimes called a decon- tamination tunnel. The tunnel may be a chamber which holds the water to be decontaminated a certain period of time such that the gasses interact with the water to oxidize the critical zo compounds in the water. Water flow through tunnel 14 is oxygenated and cleaned. Rudder 20 controls the direction of vessel 10 and deflector blade or vane 22 controls the direction of the output flow of oxygenated water either directly astern of the vessel or directly downwards into lower depths of the 25 body of water as generally shown in FIG. 9. The flow path varies from full astern to full down. Lifting mechanism 24 operates to lift deflector blade 22 from the lowered position shown in FIG. 1 to a raised position shown in FIG. 8A. Blade 22 can be placed in various down draft positions to alter the 30 ejected flow of the oxygenated, partially treated water from the body of water surrounding vessel 10. The crew may occupy cabin 26. A trash canister 28 receives trash from trash bucket 30. Trash bucket 30 is raised and lowered along vertical guide 32. Similar numerals designate 35 similar items throughout the drawings. FIG. 2 diagrammatically shows a side elevational view of vessel 10 without the trash bucket and without cabin 26. It should be noted that the waterborne vessel need not include trash container 28 and trash gathering bucket 30. The vessel 40 includes oxygenation system 12 which oxygenates a flow of water through underwater tunnel 14. FIG. 3 diagrammatically illustrates a top schematic view of vessel 10. Bow 34 has laterally extending bow wings 36, 38 that permit a flow of water into an upper deck region. Trash 45 bucket 30 is lowered into this flow of water on the upper deck to capture floating debris and trash from the water being cleaned by the vessel 10. The trash bucket 30 (FIG. 1) is then raised and the contents of bucket 30 is poured over into trash container 28. The extended position of bow wings 36, 38 is 5o shown in dashed lines. FIG. 4A shows one embodiment of the oxygenation sys- tem. A source of oxygen 40, commonly atmospheric oxygen gas, is supplied to a gas manifold 42. In addition, oxygen gas (atmospheric oxygen gas) is supplied to extractor 43 (manu- 55 factured by Pacific Ozone) which creates pure oxygen and the pure oxygen is fed to a corona discharge ozone generator 44. The corona discharge ozone generator 44 generates pure ozone gas which gas is applied to gas manifold 42.Ozone plus hydroxyl radical gases are created by a generator 46 which 60 includes a UV light device that generates both ozone and hydroxyl radical gases. Oxygen and some gaseous water (such as present in atmospheric oxygen) is fed into generator 46 to create the ozone plus hydroxyl radical gases. The ozone plus hydroxyl radical gases are applied to gas manifold 42. 65 Atmospheric oxygen from source 40 is also applied to gas manifold 42. Although source oxygen 40 could be bottled 4 oxygen and not atmospheric oxygen (thereby eliminating extractor 43), the utilization of bottled oxygen increases the cost of operation of oxygenation system 12. Also, the gas fed to generator 46 must contain some water to create the hydroxyl radical gas. A pressure water pump 48 is driven by a motor M and is supplied with a source of water. Pressurized water is supplied to air/gas manifold 50. Water/gas manifold 50 independently mixes ozone and pressurized water as com- pared with ozone plus hydroxyl radical gas plus pressurized water as compared with atmospheric oxygen plus pressurized water. In the preferred embodiment, water is fed through a decreasing cross -sectional tube section 52 which increases the velocity of the water as it passes through narrow construc- tion 54. A venturi valve (shown in FIG. 4B) draws either ozone or ozone plus hydroxyl radical gas or atmospheric oxygen into the restricted flow zone 54. The resulting water - gas mixtures constitute first, second and third oxygenated water mixtures. The venturi valve pulls the gases from the generators and the source without requiring pressurization of the gas. FIG. 4B shows a venturi valve 56 which draws the selected gas into the pressurized flow of water passing through narrow restriction 54. FIG. 4C shows that oxygenated water carrying ozone can be generated using a UV ozone generator 45. Water is sup- plied to conduit 47, the water passes around the UV ozone generator and oxygenated water is created. This oxygenated water is ultimately fed into the decontamination tunnel which is described more fully in connection with the manifold sys- tem 50 in FIG. 4A. In FIG. 4A, different conduits, such as conduits 60A, 60B and 60C, for example, carry ozone mixed with pressurized water (a first oxygenated water mixture) and ozone plus hydroxyl radical gas and pressurized water (a second oxygen- ated water mixture) and atmospheric oxygen gas plus pres- surized water (a third oxygenated water mixture), respec- tively which mixtures flow through conduits 60A, 60B and 60C into the injector site in the decontamination tunnel. The output of these conduits, that is conduit output ports 61A, 61B and 61C, are separately disposed both vertically and laterally apart in an array at intake 62 of tunnel 14 (see FIG. 1). Although three oxygenated water mixtures are utilized herein, singular gas injection ports may be used. FIG. 12 shows atmospheric oxygen gas from source 40 which is first pressurized by pump 180 and then fed to extrac- tor 43 to produce pure ozone, and ozone plus hydroxyl radical gas UV generator 46 and is fed to conduits carrying just the pressurized oxygen to injector matrix 182. The pure oxygen from extractor 43 is fed to an ozone gas generator 44 with a corona discharge. These three pressurized gases (pure ozone, ozone plus hydroxyl radical gas and atmospheric oxygen) is fed into a manifold shown as five (5) injector ports for the pure ozone, four (4) injector ports for the ozone plus hydroxyl radical gas and six (6) ports for the pressurized atmospheric oxygen gas. This injector matrix can be spread out vertically and laterally over the intake of the decontamination tunnel as shown in connection with FIGS. 4A and 5. FIG. 5 diagrammatically illustrates a side elevational sche- matic view of oxygenation system 12 and, more particularly, tunnel 14 of the waterborne vessel. A motor 59 drives a propeller in propeller region 18. In a preferred embodiment, when gills 16 are open (see FIG. 6), propeller in region 18 creates a flow of water through tunnel 14 of oxygenation system 12. A plurality of conduits 60 each independently carry either an oxygenated water mixture with ozone or an oxygenated water mixture with ozone plus hydroxy radical gases or an oxygenated water mixture with atmospheric oxy- US 7,947,172 B2 5 gen. These conduits are vertically and laterally disposed with outputs in an array at the intake 64 of the tunne114. Aplurality of baffles, one of which is baffle 66, is disposed downstream of the conduit output ports, one of which is output port 61A of conduit 60A. Tunnel 14 may have a larger number of baffles s 66 than illustrated herein. The baffles create turbulence which slows water flow through the tunnel and increases the cleans- ing of the water in the tunnel with the injected oxygenated mixtures due to additional time in the tunnel and turbulent flow. FIG. 6 diagrammatically shows a schematic top view of oxygenation system 12. The plurality of conduits, one of which is conduit 60A, is disposed laterally away from other gas/water injection ports at intake 64 of tunnel 14. In order to supersaturate a part of the water flow, a diversion channel 70 is disposed immediately downstream a portion or all of con- duits 60 such that a portion of water flow through tunnel intake 64 passes into diversion channel 70. Downstream of diversion channel 70 is a reverse flow channel 72 The flow is shown in dashed lines through diversion channel 70 and 20 reverse flow channel 72. The primary purposes of diversion channel 70 and reverse flow channe172 are to (a) segregate a portion of water flow through tunnel 14; (b) inject, in a pre- ferred embodiment, ozone plus hydroxyl radical gas as well as atmospheric oxygen into that sub -flow through diversion 25 channel 70; and (c) increase the time the gas mixes and interacts with that diverted channel flow due to the extended time that diverted flow passes through diversion channel 70 and reverse flow channel 72. These channels form a super - saturation channel apart from main or primary flow through tunnel 14. Other flow channels could be created to increase the amount of time the hydroxyl radical gas oxygenated water mixture interacts with the diverted flow. For example, diver- sion channel 70 may be configured as a spiral or a banded sub -channel about a cylindrical tunnel 14 rather than config- ured as both a diversion channel 70 and a reverse flow channel 72. A singular diversion channel may be sufficient. The cleansing operation of the decontamination vessel is depen- dent upon the degree of pollution in the body of water sur- rounding the vessel. Hence, the type of oxygenated water and the amount of time in the tunnel and the length of the tunnel and the flow or volume flow through the tunnel are all factors which must be taken into account in designing the decontami- nation system herein. In any event, supersaturated water and gas mixture is created at least the diversion channel 70 and then later on in the reverse flow channe172. The extra time the entrapped gas is carried by the limited fluid flow through the diversion channels permits the ozone and the hydroxyl radical gas to interact with organic components and other composi- tions in the entrapped water, cleaning the water to a greater degree as compared with water flow through central region 76 of primary tunnel 14. In the preferred embodiment, two reverse flow channels and two diversion channels are pro- vided on opposite sides of a generally rectilinear tunnel 14. FIG. 4A shows the rectilinear dimension of tunnel 14. Other shapes and lengths and sizes of diversion channels may be used. When the oxygenation system is ON, gills 16 are placed in their outboard position thereby extending the length of tunnel 14 through an additional elongated portion of vessel 10. See FIG. 1. Propeller in region 18 provides a propulsion system for water in tunnel 14 as well as a propulsion system for vessel 10. Other types of propulsion systems for vessel 10 and the water through tunnel 14 may be provided. The important point is that water flows through tunnel 14 and, in a preferred embodiment, first, second and third oxygenated water mix- 6 tures (ozone+pressurized water; ozone+hydroxyl radical gas+pressurized water; and atmospheric oxygen+pressurized water) is injected into an input region 64 of a tunnel which is disposed beneath the waterline of the vessel. In the preferred embodiment, when gills 16 are closed or are disposed inboard such that the stem most edge of the gills rest on stop 80, vessel 10 can be propelled by water flow entering the propeller area 18 from gill openings 80A, 80B. When the gills are closed, the oxygenation system is OFF. to FIG. 7 diagrammatically illustrates the placement of vari- ous conduits in the injector matrix. The conduits are specially numbered or mapped as 1-21 in FIG. 7. The following Oxy- genation Manifold Chart shows what type of oxygenated water mixture which is fed into each of the specially num- 15 bered conduits and injected into the intake 64 of tunnel 14. Oxygenation Manifold Chart Gas Tubes 03 + OH 03 02 1,8,16; 7,15, 17 3,4,5,11,12,13 2, 9, 10,18, 20; 6, 14,19, 21 As noted above, generally an ozone plus hydroxyl radical gas oxygenated water mixture is fed at the forward -most points of diversion channel 70 through conduits 7,15,17, 1, 8 and 16. Pure oxygen (in the working embodiment, atmo- 30 spheric oxygen) oxygenated water mixture is fed generally downstream of the hydroxyl radical gas injectors at conduits 19, 21, 18, 20. Additional atmospheric oxygen oxygenated water mixtures are fed laterally inboard of the hydroxyl radi- cal gas injectors at conduits 6, 14, 2, 9, and 10. In contrast, 35 ozone oxygenated water mixtures are fed at the intake 64 of central tunnel region 76 by conduit output ports 5, 4, 3,13,12, and 11. Of course, other combinations and orientations of the first, second and third oxygenated water mixtures could be injected into the flowing stream of water to be decontami- 4o nated. However, applicant currently believes that the ozone oxygenated water mixtures has an adequate amount of time to mix with the water from the surrounding body of water in central tunnel region 76 but the hydroxyl radical gas from injectors 7, 15, 17, 1, 8, 16 need additional time to clean the 45 water and also need atmospheric oxygen input (output ports 19, 21, 8, 20) in order to supersaturate the diverted flow in diversion channel 70 and reverse flow channel 17. The super- saturated flow from extended channels 70, 72 is further injected into the mainstream tunnel flow near the tunnel flow 50 intake. Further additional mechanisms can be provided to directly inject the ozone and the ozone plus hydroxyl radical gas and the atmospheric oxygen into the intake 64 of tunne114. Direct gas injection may be possible although water through -put ss may be reduced. Also, the water may be directly oxygenated as shown in FIG. 4C and then injected into the tunnel. The array of gas injectors, the amount of gas (about 5 psi of the outlets), the flow volume of water, the water velocity and the size of the tunnel (cross -sectional and length) all affect the 60 degree of oxygenation and decontamination. Currently, flow through underwater channel 14 is, at a minimum, 1000 gallons per minute and, at a maximum, a flow of 1800 gallons per minute is achievable. Twenty-one oxy- genated water mixture output jets are distributed both verti- 65 cally (FIGS. 4A and 5) as well as laterally and longitudinally (FIGS. 6 and 7) about intake 64 of tunnel 14. It is estimated that the hydroxyl radical gas needs about 5-8 minutes of US 7,947,172 B2 7 reaction time in order to change or convert into oxygen. Applicant estimates that approximate 15-25% of water flow is diverted into diversion channel 70. Applicant estimates that water in the diversion channel flows through the diverters in approximately 5-7 seconds. During operation when the oxy- s genation system is operating, the boat can move at 2-3 knots. The vessel need not move in order to operate the oxygenation system. FIG. 8 shows an altemative embodiment which is possible but seems to be less efficient. A supply of oxygen 40 is fed into 10 an ozone generator 44 with a corona discharge. The output of ozone gas is applied via conduit 90 into a chamber 92. Atmo- spheric oxygen or air 94 is also drawn into chamber 92 and is fed into a plurality of horizontally and vertically disposed nozzles 96. Manifold 98 consists of a plurality of oxygenation 15 nozzles 96. Manifold 98 can be raised or lowered by any appropriate means. In the illustrated embodiment, rotating threaded sleeve 110 operates on threaded rod 112 to raise and lower oxygenation manifold 98. Diverter blade 22 can be raised and lowered by another mechanism generally shown as 20 lifting mechanism 24 in FIG. 1. Shaft 114 drives propeller 116 to provide a propulsion system to move water through tunnel 118. FIG. 8A shows that the water propulsion system to move the water through the tunnel could be forward the tunnel intake 64 shown in FIG. 6. The alternative embodiment 25 also shows that the tunnel may be foreshortened. FIG. 8B is a detail showing gas injection nozzle 96 and water flow 120 passing through restricted flow channel 122. FIG. 9 diagrammatically shows that diversion blade 22, when rotated downward as shown by arrow 142, directs oxy- 30 genated and treated water output 144 downwardly into lower depths of the body of water being treated by vessel 10. FIG. 10 diagrammatically illustrates aeration injector manifold 98. FIG. 11 shows aeration injectors 96 having a forward 35 inverted V shaped body 160 and a rearward generally oval shaped body 162. Air plus ozone is pumped or drawn into the interior region 164 of V shaped body 160. Water flow is directed through constricted channel 122 and a high degree of turbulence in region 166 mixes the ozone with the water flow ao through constricted channe1122. This turbulence in restricted flow channel 122 causes the ozone and atmospheric oxygen to mix with the water flow thereby oxygenating the water. FIG. 12 shows a pressurized gas system which has been described earlier. 45 The claims appended hereto are meant to cover modifica- tions and changes within the scope and spirit of the present invention.

The present invention relates to a waterborne vessel with an oxygenation system which decontaminates surrounding water and a method therefor. BACKGROUND OF THE INVENTION Ozone (03) is one of the strongest oxidizing agents that is readily available. It is known to eliminate organic waste, reduce odor and reduce total organic carbon in water. Ozone is created in a number of different ways, including ultraviolet (UV) light, and corona discharge of electrical current through a stream of air or other gazes oxygen stream, among others. Ozone is formed when energy is applied to oxygen gas (OD. The bonds that hold oxygen together are broken and three oxygen molecules are combined to form two ozone mol- ecules. The ozone breaks down fairly quickly and as it does so it reverts back to pure oxygen, that is, an OZ molecule. The bonds that hold the oxygen atoms together are very weak which is why ozone acts as a strong oxidant. In addition, it is known that hydroxyl radicals OH also act as a purification gas. Hydroxyl radicals are formed when ozone, ultraviolet radiation and moisture are combined. Hydroxyl radicals are more powerful oxidants than ozone. Both ozone and hydroxyl radical gas break down over a short period of time (about 8-15 minutes) into oxygen. Hydroxyl radical gas is a condition in the fluid or gaseous mixture. Some bodies of water have become saturated with high levels of natural or man made materials which have a high biological oxygen demand and which in turn have created an eutrophic or anaerobic environment. It would be beneficial to clean these waters utilizing the various types of ozone and hydroxyl radical gases. OBJECTS OF THE INVENTION 10 15 20 25 30 35 40 It is an object of the present invention to provide a water- borne vessel with an oxygenation system and a method to decontaminate surrounding water. It is a further object of the present invention to provide an oxygenation system on a waterbome vessel and a method of 45 decontamination wherein ozone and/or hydroxyl radical gas is injected, mixed and super saturated with a flow of water through the waterborne vessel. It is an additional object of the present invention to provide a super saturization channel which significantly increases the 50 amount of time the ozone and/or hydroxyl radical gas mixes in a certain flow volume of water thereby oxygenating the water and decontaminating that defined volume of flowing water prior to further mixing with other water subject to additional oxygenation in the waterborne vessel. 55 It is an additional object of the present invention to provide a mixing manifold to mix the ozone independent with respect to the hydroxyl radical gas and independent with respect to atmospheric oxygen and wherein the resulting oxygenated water mixtures are independently fed into a confined water 60 bound space in the waterborne vessel to oxygenate a volume of water flowing through that confined space. SUMMARY OF THE INVENTION 65 The waterbome vessel, in one embodiment, utilizes an underwater tunnel through which passes flowing water, an 2 ozone gas generator, an ozone plus hydroxyl radical gas gen- erator and a source of atmospheric oxygen.A manifold mixer mixes pressurized water independently with the ozone, the ozone plus hydroxyl radical gas and the atmospheric oxygen to produce corresponding oxygenated water mixtures. Each of these oxygenated water mixtures are fed via a conduit system into the confined flow of water passing through the tunnel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 5 The present invention relates to a waterborne vessel with an oxygenation system and a method to decontaminate water surround the vessel. FIG. 1 diagrammatically illustrates waterborne vessel 10 to having an oxygenation system 12 disposed in an underwater tunnel 14 beneath the waterline of vessel 10. In general, water flow is established through tunnel 14 based upon the opened/ closed position ofgills 16 and the operation of the propeller at propeller region 18. Tunnel 14 is sometimes called a decon- tamination tunnel. The tunnel may be a chamber which holds the water to be decontaminated a certain period of time such that the gasses interact with the water to oxidize the critical compounds in the water. Water flow through tunnel 14 is oxygenated and cleaned. Rudder 20 controls the direction of 20 vessel 10 and deflector blade or vane 22 controls the direction of the output flow of oxygenated water either directly astern of the vessel or directly downwards into lower depths of the body of water as generally shown in FIG. 9. The flow path varies from full astern to full down. Lifting mechanism 24 operates to lift deflector blade 22 from the lowered position shown in FIG. 1 to a raised position shown in FIG. 8A. Blade 22 can be placed in various down draft positions to alter the ejected flow of the oxygenated, partially treated water from the body of water surrounding vessel 10. 30 The crew may occupy cabin 26. A trash canister 28 receives trash from trash bucket 30. Trash bucket 30 is raised and lowered along vertical guide 32. Similar numerals designate similar items throughout the drawings. FIG. 2 diagrammatically shows a side elevational view of 35 vessel 10 without the trash bucket and without cabin 26. It should be noted that the waterborne vessel need not include trash container 28 and trash gathering bucket 30. The vessel includes oxygenation system 12 which oxygenates a flow of water through underwater tunnel 14. 40 FIG. 3 diagrammatically illustrates a top schematic view of vessel 10. Bow 34 has laterally extending bow wings 36, 38 that permit a flow of water into an upper deck region. Trash bucket 30 is lowered into this flow of water on the upper deck to capture floating debris and trash from the water being 45 cleaned by the vessel 10. The trash bucket 30 (FIG. 1) is then raised and the contents of bucket 30 is poured over into trash container 28. The extended position of bow wings 36, 38 is shown in dashed lines. FIG. 4A shows one embodiment of the oxygenation sys- so tem. A source of oxygen 40, commonly atmospheric oxygen gas, is supplied to a gas manifold 42. In addition, oxygen gas (atmospheric oxygen gas) is supplied to extractor 43 (manu- factured by Pacific Ozone) which creates pure oxygen and the pure oxygen is fed to a corona discharge ozone generator 44. 55 The corona discharge ozone generator 44 generates pure ozone gas which gas is applied to gas manifold 42. Ozone plus hydroxyl radical gases are created by a generator 46 which includes a UV light device that generates both ozone and hydroxyl radical gases. Oxygen and some gaseous water 60 (such as present in atmospheric oxygen) is fed into generator 46 to create the ozone plus hydroxyl radical gases. The ozone plus hydroxyl radical gases are applied to gas manifold 42. Atmospheric oxygen from source 40 is also applied to gas manifold 42. Although source oxygen 40 could be bottled 65 oxygen and not atmospheric oxygen (thereby eliminating extractor 43), the utilization of bottled oxygen increases the 15 25 4 cost of operation of oxygenation system 12. Also, the gas fed to generator 46 must contain some water to create the hydroxyl radical gas. A pressure water pump 48 is driven by a motor M and is supplied with a source of water. Pressurized water is supplied to water/gas manifold 50. Water/gas mani- fold 50 independently mixes ozone and pressurized water as compared with ozone plus hydroxyl radical gas plus pressur- ized water as compared with atmospheric oxygen plus pres- surized water. In the preferred embodiment, water is fed through a decreasing cross -sectional tube section 52 which increases the velocity of the water as it passes through narrow construction 54. A venturi valve (shown in FIG. 4B) draws either ozone or ozone plus hydroxyl radical gas or atmo- spheric oxygen into the restricted flow zone 54. The resulting water -gas mixtures constitute first, second and third oxygen- ated water mixtures. The venturi valve pulls the gases from the generators and the source without requiring pressuriza- tion of the gas. FIG. 4B shows a venturi valve 56 which draws the selected gas into the pressurized flow of water passing through narrow restriction 54. FIG. 4C shows that oxygenated water carrying ozone can be generated using a UV ozone generator 45. Water is sup- plied to conduit 47, the water passes around the UV ozone generator and oxygenated water is created. This oxygenated water is ultimately fed into the decontamination tunnel which is decribed more fully in connection with the manifold system 50 in FIG. 4A. In FIG. 4A, different conduits, such as conduits 60A, 60B and 60C, for example, carry ozone mixed with pressurized water (a first oxygenated water mixture) and ozone plus hydroxyl radical gas and pressurized water (a second oxygen- ated water mixture) and atmospheric oxygen gas plus pres- surized water (a third oxygenated water mixture), respec- tively which mixtures flow through conduits 60A, 60B and 60C into the injector site in the decontamination tunnel. The output of these conduits, that is conduit output ports 61A, 61B and 61C, are separately disposed both vertically and laterally apart in an array at intake 62 of tunnel 14 (see FIG. 1). Although three oxygenated water mixtures are utilized herein, singular gas injection ports may be used. FIG. 12 shows atmospheric oxygen gas from source 40 which is first pressurized by pump 180 and then fed to extrac- tor 43 to produce pure oxygen, and ozone plus hydroxyl radical gas UV generator 46 and is fed to conduits carrying just the pressurized oxygen to injector matrix 182. The pure oxygen form extractor 43 is fed to an ozone gas generator 44 with a corona discharge. These three pressurized gases (pure ozone, ozone plus hydroxyl radical gas and atmospheric oxy- gen) is fed into a manifold shown as five (5) injector ports for the pure ozone, four (4) injector ports for the ozone plus. hydroxyl radical gas and six (6) ports for the pressurized atmospheric oxygen gas. This injector matrix can be spread out vertically and laterally over the intake of the decontami- nation tunnel as shown in connection with FIGS. 4A and 5. FIG. 5 diagrammatically illustrates a side elevational sche- matic view of oxygenation system 12 and, more particularly, tunnel 14 of the waterborne vessel. A motor 59 drives a propeller in propeller region 18. In a preferred embodiment, when gills 16 are open (see FIG. 6), propeller in region 18 creates a flow of water through tunnel 14 of oxygenation system 12. A plurality of conduits 60 each independently carry either an oxygenated water mixture with ozone or an oxygenated water mixture with ozone plus hydroxy radical gases or an oxygenated water mixture with atmospheric oxy- gen. These conduits are vertically and laterally disposed with outputs in an array at the intake 64 of the tunnel 14. Aplurality US 7,517,459 B2 5 of baffles, one of which is baffle 66, is disposed downstream of the conduit output ports, one of which is output port 61A of conduit 60A. Tunnel 14 may have a larger number of baffles 66 than illustrated herein. The baffles create turbulence which slows water flow through the tunnel and increases the cleans- 5 ing of the water in the tunnel with the injected oxygenated mixtures due to additional time in the tunnel and turbulent flow. FIG. 6 diagrammatically shows a schematic top view of oxygenation system 12. The plurality of conduits, one of 10 which is conduit 60A, is disposed laterally away from other gas/water injection ports at intake 64 of tunnel 14. In order to supersaturate a part of the water flow, a diversion channel 70 is disposed immediately downstream a portion or all of con- duits 60 such that a portion of water flow through tunnel 1s intake 64 passes into diversion channel 70. Downstream of diversion channel 70 is a reverse flow channel 72. The flow is shown in dashed lines through diversion channel 70 and reverse flow channel 72. The primary purposes of diversion channel 70 and reverse flow channel 72 are to (a) segregate a 20 portion of water flow through tunnel 14; (b) inject, in a pre- ferred embodiment, ozone plus hydroxyl radical gas as well as atmospheric oxygen into that sub -flow through diversion channel 70; and (c) increase the time the gas mixes and interacts with that diverted channel flow due to the extended 25 time that diverted flow passes through diversion channel 70 and reverse flow channel 72. These channels form a super - saturation channel apart from main or primary flow through tunnel 14. Other flow channels could be created to increase the 30 amount of time the hydroxyl radical gas oxygenated water mixture interacts with the diverted flow. For example, diver- sion channel 70 may be configured as a spiral or a banded sub -channel about a cylindrical tunnel 14 rather than config- ured as both a diversion channel 70 and a reverse flow channel 35 72. A singular diversion channel may be sufficient. The cleansing operation of the decontamination vessel is depen- dent upon the degree of pollution in the body of water sur- rounding the vessel. Hence, the type of oxygenated water and the amount of time in the tunnel and the length of the tunnel 40 and the flow or volume flow through the tunnel are all factors which must be taken into account in designing the decontami- nation system herein. In any event, supersaturated water and gas mixture is created at least the diversion channel 70 and then later on in the reverse flow channel 72. The extra time the as entrapped gas is carried by the limited fluid flow through the diversion channels permits the ozone and the hydroxyl radical gas to interact with organic components and other composi- tions in the entrapped water, cleaning the water to a greater degree as compared with water flow through central region 76 so of primary tunnel 14. In the preferred embodiment, two reverse flow channels and two diversion channels are pro- vided on opposite sides of a generally rectilinear tunnel 14. FIG. 4A shows the rectilinear dimension of tunnel 14. Other shapes and lengths and sizes of diversion channels may be ss used. When the oxygenation system is ON, gills 16 are placed in their outboard positionthereby extending the length of tunnel 14 through an additional elongated portion of vessel 10. See FIG. 1. Propeller in region 18 provides a propulsion system 60 for water in tunnel 14 as well as apropulsion system for vessel 10. Other types of propulsion systems for vessel 10 and the water through tunnel 14 may be provided. The important point is that water flows through tunnel 14 and, in a preferred embodiment, first, second and third oxygenated water mix- 65 tures (ozone+pressurized water; ozone+hydroxyl radical gas+pressurized water, and atmospheric oxygen+pressurized 6 water) is injected into an input region 64 of a tunnel which is disposed beneath the waterline of the vessel. In the preferred embodiment, when gills 16 are closed or are disposed inboard such that the stern most edge of the gills rest on stop 80, vessel 10 can be propelled by water flow entering the propeller area 18 from gill openings 80A, 80B. When the gills are closed, the oxygenation system is OFF. FIG. 7 diagrammatically illustrates the placement of vari- ous conduits in the injector matrix. The conduits are specially numbered or mapped as 1-21 in FIG. 7. The following Oxy- genation Manifold Chart shows what type of oxygenated water mixture which is fed into each of the specially num- bered conduits and injected into the intake 64 of tunnel 14. Oxveenation Manifold Chart Gas Tubes 03+OH 1,8,16;7,15,17 03 3, 4, 5, 11,12, 13 02 2, 9,10,18, 20; 6, 14,19, 21 As noted above, generally an ozone plus hydroxyl radical gas oxygenated water mixture is fed at the forward -most points of diversion channel 70 through conduits 7, 15,17,1, 8 and 16. Pure oxygen (in the working embodiment, atmo- spheric oxygen) oxygenated water mixture is fed generally downstream of the hydroxyl radical gas injectors at conduits 19, 21, 18, 20. Additional atmospheric oxygen oxygenated water mixtures are fed laterally inboard of the hydroxyl radi- cal gas injectors at conduits 6, 14, 2, 9, and 10. In contrast, ozone oxygenated water mixtures are fed at the intake 64 of central tunnel region 76 by conduit output ports 5, 4, 3,13,12, and 11. Of course, other combinations and orientations of the first, second and third oxygenated water mixtures could be injected into the flowing stream of water to be decontami- nated. However, applicant currently believes that the ozone oxygenated water mixtures has an adequate amount oftime to mix with the water from the surrounding body of water in central tunnel region 76 but the hydroxyl radical gas from injectors 7, 15, 17, 1, 8, 16 need additional time to clean the water and also need atmospheric oxygen input (output ports 19, 21, 8, 20) in order to supersaturate the diverted flow in diversion channel 70 and reverse flow channel 17. The super- saturated flow from extended channels 70, 72 is further injected into the mainstream tunnel flow near the tunnel flow intake. Further additional mechanisms can be provided to directly inject the ozone and the ozone plus hydroxyl radical gas and the atmospheric oxygen into the intake 64 of tunne114. Direct gas injection may be possible although water through -put may be reduced. Also, the water may be directly oxygenated as shown in FIG. 4C and then injected into the tunnel. The array of gas injectors, the amount of gas (about 5 psi of the outlets), the flow volume of water, the water velocity and the size of the tunnel (cross -sectional and length) all affect the degree of oxygenation and decontamination. Currently, flow through underwater channel 14 is, at a minimum, 1000 gallons per minute and, at a maximum, a flow of 1800 gallons per minute is achievable. Twenty-one oxy- genated water mixture output jets are distributed both verti- cally (FIGS. 4A and 5) as well as laterally and longitudinally (FIGS. 6 and 7) about intake 64 of tunnel 14. It is estimated that the hydroxyl radical gas needs about 5-8 minutes of reaction time in order to change or convert into oxygen. Applicant estimates that approximate 15-25% of water flow is US 7,517,459 B2 7 diverted into diversion channel 70. Applicant estimates that water in the diversion channel flows through the diverters in approximately 5-7 seconds. During operation when the oxy- genation system is operating, the boat can move at 2-3 knots. The vessel need not move in order to operate the oxygenation system. FIG. 8 shows an alternative embodiment which is possible but seems to be less e$icient.A supply of oxygen 40 is fed into an ozone generator 44 with a corona discharge. The output of ozone gas is applied via conduit 90 into a chamber 92. Atmo- spheric oxygen or air 94 is also drawn into chamber 92 and is fed into a plurality of horizontally and vertically disposed nozzles 96. Manifold 98 consists of a plurality of oxygenation nozzles 96. Manifold 98 can be raised or lowered by any appropriate means. In the illustrated embodiment, rotating threaded sleeve 110 operates on threaded rod 112 to raise and lower oxygenation manifold 98. Diverter blade 22 can be raised and lowered by another mechanism generally shown as lifting mechanism 24 in FIG. 1. Shaft 114 drives propeller 116 to provide a propulsion system to move water through tunnel 118. FIG. 8A shows that the water propulsion system to move the water through the tunnel could be forward the tunnel intake 64 shown in FIG. 6. The alternative embodiment also shows that the tunnel may be foreshortened. FIG. 8B is a detail showing gas injection nozzle 96 and water flow 120 passing through restricted flow channel 122. FIG. 9 diagrammatically shows that diversion blade 22, when rotated downward as shown by arrow 142, directs oxy- genated and treated water output 144 the oxygenation sys- tems into lower depths of the body of water being treated by vessel 10. FIG. 10 diagrammatically illustrates aeration injector manifold 98. FIG. 11 shows aeration injectors 96 having a forward inverted V shaped body 160 and a rearward generally oval shaped body 162. Air plus ozone is pumped or drawn into the interior region 164 of V shaped body 160. Water flow is directed through constricted channel 122 and a high degree of turbulence in region 166 mixes the ozone with the water flow through constricted channel 122. This turbulence in restricted flow channel 122 causes the ozone and atmospheric oxygen to mix with the water flow thereby oxygenating the water. FIG. 12 shows a pressurized gas system which has been described earlier.

MARKET RESEARCH Contract No.: Sole Source 19-20-014 Current Term: N/A Expiration Date: N/A Title: Scavenger 2000 Depollution Vessel Services Recommendation: // Sole Source Contract jl Solicit Competition ❑ Access Contract 7 Other Procurement Contracting Officer: Victoria Giraido Background: The City of Miami's Department of Resilience and Public Works ("Public Works") has the need for the continuity of services for the collection of floatable debris in the water surface and aeration of water with a combination of ozone and oxygen, under the jurisdiction of the City of Miami ("City") including the Biscayne Bay area, navigable tributaries and its marinas. Floatable debris are considered to be any material floating within the first two (2) feet of water and include, but are not limited, to aluminum cans, plastic bags, toys, vegetation, animal debris, wood, leaves, etc. The collected debris is stored at selected staging areas and eventually taken to the Miami -Dade County disposal facilities at the Contractor's expense. The vessel provides oxygen aeration and decontamination treatment within authorized navigable bodies of water. There is an annual water analysis report provided to the City which captures varying parameters such as fecal coliform, total coliform, bacteria count, algae count, Potential Hydrogen (pH), and temperature. Public Works currently uses the services of Scavenger2000 decontamination vessel from Water Management Technologies, Inc. ("WMT"), which was initially procured as a sole source and the current contract expires December 3, 2019. An emergency purchase order for $25,000.00 was issued to cover costs for continuity of services until Commission approval is granted. Research Conducted: Market research was conducted using various state and county contract databases to source any current contracts that the City could potentially use to piggyback or find other related vendors that could provide same to similar services. After a thorough review, the Department of Procurement ("Procurement") was unable to find any similar contracts in the databases visited. In addition to doing research on various state and county contract databases, an internet search was conducted in order to gauge the market and to verify whether there were any other companies that could provide the same or similar service as WMT. However, no comparable contracts were located. Comparable Contracts: No other comparable contracts were located. Recommendation: Procurement recommends that the City continues to use the services of WMT, as they are the Sole Source provider of the Scavenger2000 vessel. Procurement found that while there are other companies who perform limited services to pick up floatable debris from various bodies of water, their vessels are not equipped with a patented Oxy-Plus water decontamination system which allows for oxygenation and decontamination as the floatable debris is being collected and can provide valuable data for the City's resilience plan.
