The S.C. Newark Bay
An Innovative Method of Removing Debris
UNITED MARINE INTERNATIONAL li£
On July 14, 1999, Governor Christine Todd Whitman and Passaic Valley
Sewerage Commissioners (PVSC) christened the Skimmer Vessel "S. V.
Newark Bay", a`boat specially designed to remove "floatables" (debris
Worldwide Applications found on the water's surface) from the Passaic River and Newark Bay.
UMI in the hews PVSC purchased the 50 -foot pontoon -style trash skimmer (a United
Marine International TRASHCATTM model) through a grant from the
Technical Papers State Office of Maritime Resources.

The vessel uses a system of hydraulically controlled conveyors to
remove floatables that are mainly due to combined and storm sewer
overflows that occur during rainstorms. The skimmer can retrieve items
up to four and one-half feet in diameter, and has the capacity to contain
up to six tons of trash. Currently in the works are Stormwater
Management and Combined Sewer Overflow Abatement projects that
will greatly reduce the river's floatable burden. In the meantime,
shoreline cleanups and the "S. V. Newark Bay" will go a long way toward
achieving a trash -free river.
The skimmer completed several preliminary outings and cleanup
missions last fall, and will soon come out of dry dock to begin its first full
season of cleanups. The scheduling of TRASHCATTM forays will be
determined largely by conditions on the river. The higher lunar tides
accompanying new and full moons typically bring more trash to the

middle of the river. These will be prime opportunities for PVSC to make
the best use of the skimmer boat. The vessel will also be used to
supplement volunteer shoreline cleanup events.
Communities such as North Arlington and Lyndhurst, and volunteer
groups such as New Jersey Community Water Watch, have been
picking up trash along the Passaic River shorelines for many years. In
1998, a program was launched that helps these and other concerned
and dedicated groups in their efforts to revive a river system that was
once one of the most polluted systems in the United States.
Administered by Passaic Valley Sewerage Commissioners (PVSC), with
advocacy and coordination assistance from the Passaic River Coalition
(PRC), this program is entitled the Passaic River/Newark Bay
Restoration Program: Shoreline Cleanup Element. Through the
Program, PVSC not only implements an independent cleanup effort
utilizing PVSC employees and the skimmer boat "S. V. Newark Bay", but
also brings considerable organizational infrastructure and financial
resources to its volunteer cleanup sponsorship role. PVSC supplies
participating municipalities, service organizations, schools, businesses,
and concerned citizens with resources for a successful cleanup event.
These resources include gloves, trash bags, boots, waders, rakes and
anything else the volunteers may need. PVSC also provides dumpsters
and hauling free of charge, and pays the dump charges for the river
trash.
The cleanups, which take place from March through December, have
resulted in the removal of hundreds of tons of trash and debris from the
river. This not only enhances the river's overall health, but also improves
its appearance and aesthetic appeal. In addition, the program is a great
community -builder that fosters appreciation and respect for the Passaic
River, an invaluable natural resource.

VESSEL WITH OXYGENATION SYSTEM
AND DECONTAMINATION METHOD
Technical Field
PCT/US2005/029084
[0001] The present invention relates to a waterborne vessel with an
oxygenation system which decontaminates surrounding water and a method therefor.
Background
[0002] 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 (02). The bonds that hold oxygen together are broken and
three oxygen molecules are combined to form two ozone molecules. 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 weals which
is why ozone acts as a strong oxidant. In addition, it is kaouni 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.
[0003] Some bodies of water have become saturated with high levels of
natural or man made materials which have a high biological oxygen deznand and
which in tum 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.

t-annel through which passes flowing water, an ozone gas generator, an ozone plus

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 charnel 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 oxygen water mixtures. A
decontamination method is also provided.
[0005] One advantage of the present invention is to provide a waterborne
vessel with an oxygenation system and a metho d to decontaminate surrounding water
wherein ozone and/or hydroxyl radical gas is injected, mixed and supersaturated with
a flow of water through the waterborne vessel.
[0006] Another advantage of the present invention is 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 water
prior to further mixing with other water subject to additional oxygenation in the
waterborne vessel.
[0007] A Ru they advantage of the present invention is to provide a mixing
manifold to rnix 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 bound space
in the waterborne vessel to oxygenate a volume of water flowing through that
confined space.

Best Mode for Carrying Out Invention
[0024] The present invention relates to a waterborne vessel with an
oxygenation system and a method to decontaminate water surround the vessel.
[0025] 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/closed position of gills 16 and the operation of the propeller at propeller
region 18. Tunnel 14 is sometimes called a decontamination 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 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.
[0026] 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.
[0027] 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 ----- - -
includes oxygenation system 14 which oxygenates a flow of water through
underwater tunnel 14.

[0028] 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 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.
[0029] FIG. 4A shows one embodiment of the oxygenation system. 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
(manufactured 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 includes aUV 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. Atmospheric oxygen from source 40 is also applied to gas
manifold 42. Although source oxygen 40 could be bottled 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 suppliedto air/gas-manifold 50 Water/gas i- aiiifold 50
independently mixes ozone and pressurized water as compared 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 construction 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
WO 2006/026150 PCT/US2005/029084

thud oxygenated water mixtures. The ventri valve pulls the gases from the generators
and the source without requiring pressurization of the gas.
[0030] FIG. 4B shows a ventu i valve 56 which draws the selected gas into
the pressurized flow of water passing through narrow restriction 54.
[0031] FIG. 4C shows that oxygenated water carrying ozone can be generated
using a W ozone generator 45. Water is supplied 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 system 50 in FIG. 4A.
10032] 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
oxygenated water mixture) and atmospheric oxygen gas plus pressurized water (a:
third oxygenated water mixture), respectively 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.
[0033] FIG. 12 shows atmospheric oxygen gas from source 40 which is first
pressurized by pump 180 and then fed to extractor 43 to produce pure ozone, and
ozone plus hydroxyl radical gas W generator 46 and is fed to conduits carrying just
the pressurized oxygen to injector matrix 182. The pure ozone 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 oxygen) is fed
into a manifold shown as five (5) injector ports for the pure ozone, four (4) inj ector
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
FIG. 4A and 5.

[0034] FIG. 5 diagranimatically illustrates a side elevational schematic 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 watermixture with ozone or an oxygenated
water mixture with ozone plus hydroxy radical gases or an oxygenated water mixture
with atmospheric oxygen. These conduits are vertically and laterally disposed with
outputs in an array at the intake 64 of the tunnel 14. A plurality 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 cleansing of the water in the tunnel with the
inj ected oxygenated mixtures due to additional time in the tunnel and turbulent flow.
[0035] 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 conduits 60 such that a portion of water flow through
tunnel intake 64 passes into diversion channel 70. Downstream of diversion chamiel 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 portion of water flow through tunnel 14; (b)
- inj ect, in a preferred 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 time that diverted
flow passes through diversion channel 70 and reverse flow channel 72. These channels
-- -- - - -- -- -- - - ---- _--form-a supersaturation -channel -apart from main_or_primary flow through.tunnel_.14._ _
[0036] 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, diversion channel 70 may be configured as a spiral or a banded sub -channel
WO 2006/026150
0
PCT/US2005/029084
about a cylindrical tunnel 14 rather than configured as both a diversion chamiel 70 and a
reverse flow channel 72. A singular diversion channel may be sufficient. The cleansing
operation of the decontamination vessel is dependent upon the degree of pollution in the
body of water surrounding 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
decontamination 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 entrapped gas is carried by the limited fluid flow through the diversion
chaamels permits the ozone and the hydroxyl radical gas to interact with organic
components and other compositions in the entrappedwater, cleaningthe waterto 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
provided 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.
[0037] 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 tumel 14 may be provided. The important
point is that water flows through tunnel 14 and, in a preferred embodiment, first, second
and third oxygenated waterinixtures (ozone+pressurized water; ozone+hydroxyl radical
gas + pressurized water; and atmospheric oxygen + pressurized water) is injected into an
input red on 64 of a tunnel which is disposed beneath the waterline of the vessel.
[0038] 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

[0039] FIG. 7 diagrammatically illustrates the placement of various conduits in the
injector matrix. The conduits are specially numbered or mapped as 1-21 in FIG. 7. The

[0040] As noted above, generally an ozone plus hydroxyl radical gas oxygenated

injectors at conduits 19, 21, 18, 20. Additional atmospheric oxygen oxygenated water
mixtures are fed laterally inboard of the hydroxyl radical 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 decontaminated. 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 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 supersaturated flow from extended channels 70, 72 is further injected
hito the mainstream tunnel flow near the tunnel flow intake.
[0041] Further additional mechanisms canbe provided to directly inject the ozone
-- - - - -- and the ozone plus hydroxylradicalgas .and_the_atmosphei-ic_oxygen_into the -intake. 64 of
tunnel 14. 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 5psi of the
WO 20061026150

PCT/US2005/029094
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.
[0042] Currently, flow through underwater channel 14 is, at a minimum, 1.000
gallons per minute and, at a maximum, a flow of 1800 gallons per minute is achievable.
Twenty-one oxygenated water mixture output jets are distributed both vertically (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 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 oxygenation system is operating, the boat can move at 2-3 knots. The
vessel need not move in order to operate the oxygenation system.
[0043] FIG. 8 shows an alternative embodiment which is possiblebut seems to be
less efficient. 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.
Atmospheric 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. 16. The alternative embodiment also
shows that the tunnel may be foreshortened.

Scavenger2000 Operations Report
Prepared By
Water Management Technologies, Inc.
10400 NW 33rd Street, Miami, FI 33172
954-668-6937
(March 8th, 2010)
Prepared For
City of Miami Mayor's Office
The City of Miami Commissioners Offices
City of Miami Manager's Office
CityofMiami Public Works -Director
Miami -Dade County Mayor's Office
Miami -Dade County Commissioners Offices
Miami River Commission
Congresswoman IIeana Ros-Lehtinen
It has been a pleasure for us to clean and help rejuvenate the City of Miami Waterways
and Miami River for the past several years. Our objective is to help clean the waters of
the world.
These are the results for the operation of the Scavenger2000 Decontamination Vessel
performed on the City of Miami and Miami -Dade County waterways for the period of
last five years. The City of Miami has contracted $200,000.00 per fiscal year for the
Scavenger2000 Decontamination Vessel Services to operate 20 hours per week (reduced
to $176,000.00 in the fiscal year 2009-2010), and some additional funds for more service
hours are periodically provided from Miami -Dade County and other grants when
available. In addition to these funds, a contribution of 5 or more free service hours per
week is made to the City of Miami and Miami -Dade County from the Scavenger2000
owners at no cost to the City of Miami or Miami -Dade County. This contribution
amounts to over $250,000 value over the past 5 years.
Please see below a general report of amounts of debris collected, injected oxygen, and
gallons of water disinfected through our patented Oxy -Plus system equipped
Scavenger2000.
An average of 48,572 of cubic feet of trash have been swept from the waters under the
jurisdiction of the City of Miami and Miami -Dade County over the last five years. By
removing this surface debris, we reduce contaminants in the waterways; eliminate
potential navigational collisions with normal boating traffic and prevent debris from
washing up on our shorelines. The Scavenger2000 removes debris as small as bottle caps
to large debris, such as 55 gallon drums, large dock pilings, wooden pallets, mattresses,
large wood boards, and such. Please see attached pictures.
Mother Nature provides her own set of trash items. Some of these include coconuts; palm
fronds, tree limbs, small branches, leaves and sea grass which are all collected on a
regular basis. Very strong foul odors are emitted from the floatable debris where bacteria
and other contaminants lodge themselves. The Scavenger2000's ability to remove
floatable debris and trash from the surface of the water allows nature's ability to
oxygenate the water.
_Approximately 1-2% of our trash includes_ carcasses of_dogs, _cats, and a few _small _fish
but mostly chickens, and bags of rotting meat from local fishing fleets.
We are also working closely with USCG when we find navigational hazards too large for
collection. We have found that the Coast Guard has very little resources to help discard
any navigational hazard, therefore leaving the task generally to the Scavenger2000. We
also report directly to the Department of Homeland Security in order to report any
suspicious activities under the territory of the City of Miami and Miami -Dade County.
Please attached letter from Homeland Security Department.
The Scavenger2000 has injected an average of 635 millions of liters of oxygen into the
area waters we have been working in. Attached you will find a brief description of the
benefits of oxygenation. Please find attached report for Dissolved Oxygen Levels before
and after performance of the Scavenger2000.
The Scavenger2000 has treated an average of 3,225 millions of gallons of water that were
disinfected through our Oxy -Plus decontamination system at a rate of 10 thousand
gallons of water per minute oxidizing bacteria, viruses, algae, and some nutrients.
Please see attached rate of efficiency of the Oxy -Plus System.
The Department of Environmental Resource Management (DERM) monitors the City of
Miami and Miami -Dade water quality by performing monthly e -coli and turbidity
samples which were taken at several set testing locations for the last 10 years. The
Scavenger2000 originally started its services on the Miami River in 2003. Since the
Implementation of the services of the scavenger2000 DERM's testing results indicate a
noticeable decrease in e -coli and turbidity concentration. Please see attached report from
DERM.
In the case of Turbidity tracking also provided by DERM, positive results were
immediately noticeable. Please refer to the attached Turbidity tracking report.
Because of the City of Miami's fiscal budget and yearly maintenance schedule of the
Scavenger2000 taking place in the month of September of every year, services were not
rendered over the years in the month of September. DERM's water quality testing results
indicate increases in fecal coliform and turbidity in the months of September over the last
5 years. When the Scavenger2000 services resume in October the water Quality results
indicate improvements in water quality.
Our company has conducted research on obtaining reports on the Biological Oxygen
Demand (BOD) for the City of Miami and Miami -Dade County. According to a
representative from DERM, the department does not test for BOD, therefore, no records
were found. In addition, the tests for BOD are not cost effective, and therefore not a test
performed by our company.
Please see attached letter from FDEP to the City of Miami stating, "The department has
determined that the City has met all of the requirements of this condition with the
implementation of the Scavenger2000 pollution boat and is considered to be in
compliance with this section of the consent to order".
The Scavenger's multi-purpose capabilities are a proven cost-effective addition to the
continued effort of the City of Miami to keep the waterways both clean and safe.
We have received compliments and gratitude from the following businesses along the
City of Miami Waterways including; Hurricane Cove Marina, Merrill -Stevens, Bassas
Cargo, Fennigan's River, Garcia's, Bayside Marina, Davis Canal residents, Ademar canal
residents, Grove Key Marina, just to name a few.
We are proud to be part of the City of Miami and Miami -Dade County's efforts in
combating water pollution.
We have hosted many delegations from around the world to witness the Scavenger2000
in action in our waterways, and all praise the City of Miami and Miami -Dade County for
the conscientiousness and foresight to keep our waterways clean.
Please see enclosed just a few pictures of the Scavenger2000 performing its duties on the
City of Miami and Miami -Dade County waterways... A picture is worth a thousand
words... Enjoy your accomplishments...
If you would like to see additional information or pictures, or should you have any
questions, please do not hesitate to contact me.

THE SYSTEM:
When ozone and UV light is added to the aeration/oxygenation
process of the Scavenger2000 water decontamination and
regeneration vessel, several unique abilities result in being greater
than either of the processes applied in solo. Rather than having
simply an aeration stream, a very powerful and yet, environmentally
safe, disinfection process is carried out in the waters where the
Scavenger2000 operates.
Ozone and UV Light have been applied with great benefit in the
municipal sewer treatment process worldwide, because of its ability to
disinfect water without leaving any harmful by-products as, does
chlorine. In fact, ozone was found through laboratory examination to
be over 100 times as powerful as chlorine in destroying E -Coli
bacteria.
There are no other vessels in the world today that have all the
capabilities of the Scavenger2000 water decontamination and
regeneration vessel.
BENEFITS OF COMBINED AERATION, OXYGENATION and
OZONE IN WATER
The EPA & FDA acknowlege ozone's ability to kill 99.9992% of all
pathogenic life in water.
Physical:
Reduces turbidity: Ozone alters the surface charge which allows suspended particles to
coagulate, they then are removed by sedimentation, filtration or flotation.
Odor removal: Organic and inorganic compounds containing sulfur and nitrogen are oxidized to
simple odor free compounds.
Color removal: Ozone treatment oxidizes double bonds to single bonds which are simple
compounds, generally clear. Tests at Nova University show that water clarity improved by more
than 50%.
Algae control: Algae is a natural odor generator. Ozone indirectly kills algae by oxidizing the
organic chemicals and some nutrients that algae feeds on.
Red Tides: Ozone oxidizes the toxic algae that cause red tides.
CHEMICAL:
Pesticide removal: Ozone effectively oxidizes most pesticides, insecticides, herbicides, and
fungicides that get washed into the watershed.
Increases DOC: (Dissolved Oxygen Content). The life force of the water is oxygen. Ozone is a
triatomic oxygen that becomes oxygen anywhere from a few seconds to a few minutes. This
increases the oxygen in the water.
Sheen: Ozone oxidizes some of the oil sheen in the water.
BIOLOGICAL:
Kills --pathogens: Ozone- is -a- powerful- defense against the microbial contamination of _water.
Cryptosporidium, a parasite, is one of many dangerous micro-organisms that ozone will kill. It
also kills pathogens such as physteria.
Kills fecal coliform: Often in storm water run off, there are sewage spills or agricultural waste
going directly into the waterways. Ozone can be a defense mechanism against such pollution.
Tests effectuated at Nova University have demonstrated that Fecal Coliform decreased 95% with
the use of oxygen and ozone combined..
Inactivates virus: A virus cannot survive when exposed to the ozone molecules. Tests have
proven that viruses of all kinds are inactivated when mixed with ozone. Waterborne virus is a
serious concern in our waterways.'
Ozone is safe: Chlorine and Ozone are disinfectants, but unlike chlorine, ozone is non-toxic.
Ozone also inactivates viruses in water whereas chlorine ineffective. The Scavenger2000 uses
special techniques to generate ozone and oxygen on board then drives the ozone into the water.
Depending on conditions, the ozone life expectancy can vary from a few seconds to a few
minutes where upon ozone goes back into its normal oxygen state.
The amount of dissolved ozone is so minute it only affects micro -biological pollutants. The
natural plant life is not affected due to the short contact and small concentration of ozone. Ozone
converts into oxygen in seconds. This procedure supports chemical oxygen demand (COD)
removal, cracks undegradable substances so that they become digestible to bacteria, and supports
the aerobic oxidation of toxic nitrogen compounds, allowing extremely high fish loads while at
the same time maintaining excellent water quality.

WATER MANAGEMENT TECHONOLOGIES
SCAVENGER 2000 DECONTAMINATION REPORT
On May 21, 2009, Water Management Technologies conducted a test to
determine the effectiveness of the onboard OXYPLUS
DECONTAMINATION SYSTEM. These tests took place at the Riverside
Center, located at the junction of SW 2" a Avenue and the Miami River;
Miami, Florida. The system was activated for one hour of operation: an
explanation of the conditions and results are included in this report.
The tests were conducted under the following conditions:
Slack Water
High Tide
Sunny skies
Wind — 4 to 5 MPH / ENE
Air temp. 92.2°
Water temp. 86.7°
At 10:50PM a test sample of water was taken from the starboard bow door; a
dissolved oxygen reading was also taken. At 10:50PM the Scavenger was
placed in the working mode — main engine 1,200 RPMs and Oxy -Plus at
2,300 RPMs. The vessel was held in place with 4 mooring lines. Additional
samples were taken at 15 minute intervals.
At the conclusion of the tests all samples were immediately taken to
MICRIM LABS INC.: the samples were analyzed for fecal coli form and
total coli form- _ -
CONCLUSION
The results showed that after one hour of operation the fecal coli form
count was decreased by 99%, the total coli form count reduced by 75% and
the dissolved oxygen levels were increased by 32%. The results are
expressed in the following graph:

Dear Mr. des Aulniers�
I am writing to commend the services provided thus far along the Miami River from the
Scavenger 2000 vessel. The United States Coast Guard is partially responsible for ensuring the
Miami River's designated Federal Navigable Channel is clear of any hazards to navigation. It is
my understanding that in one year of service, the Scavenger 2000 removed over 750 hazards to
navigation from the river, including but not limited to Iogs, welding cylinders, etc. The removal
of these hazards to navigation, which appear on a regular basis, have been critical to maintaining
the Miami River's safe Federal Navigable Channel for vessels to transit.
Furthermore, the U.5:'Coast Guard has a leadership role in providing Homeland Security in the
Port of the Miam ver, free from terrorism and illegal contraband. The Scavenger 2000
Captain uses a cellular camera to take pictures of any suspicious activity, and the pictures are e-
mailed real time to the U.S. Coast Guard. This service provides additional necessary
surveillance of the Miami River area, which has benefited the U.S. Coast Guard's efforts in that
regard.
I hope the Scavenger 2000 contract is renewed, so that we may continue to work in partnership
on maintaining a safe, secure, and navigable Miami River.
Sincerely,
-I�

Bear Mr. O'Hare.
Evaluation of the test results performed for Water Management
Technologies on March 26, 2001 we have found that the Scavenger 2000
using its patented Oxy -Pius system along with its aeration system is an
effective treatment for contaminated surface waters.
Monday afternoon the vessel was powered to a polluted site in a Fort
Lauderdale canal- Two untreated samples were taken. Two additional
samples were taken, 1) immediately after treatment and 2)*afler several
passes. Microscopic analysis by Dr_ Andrew Rogerson of Nova Southeastern
University was performed without his knowledge of sample origin (blind
study).
Samples were taken at the following locations and approximate times and
conditions:
1. Las Olas Hendricks Isle:carial- the sample was taken directly from
the swrface of the canal at 1:30 p.m.
2- The firstsamplewas taken from the sampling port of the water
analysis system on board the vessel immediately after treatment.
3. The second sample was taken directly from the surfac,,. of the
water of the cancel in another untreated section of the canal.
4. _ T1zis-sa»ctptq was taken after several passes_
_-
--- 5_ . The ap roxirnate flow rate was 36,487. Liters per Minute til .
treatment area at engine RPM of 1 ] a0. _ _

These results show that the combined 'oxidation treatment of your vessel did
effectively reduce the numbers of undesirable bacterial and algae species
present in the surface waterway samples. It was noted that the clarity of the
water samples increased significantly after treatment. These positive results
demonstrate that you water decontamination vessel is an effective toot in
improving coptaminated bodies of water. Supporting documentation for
these tests is available from Spectrum Laboratories and Nova South-eastern
Universi�-/ on bequest.
Please contact me if you have any further questions.

Re: testing of treated and untreated water
Dear Dr.' McCorquodale,
I have performed light microscopical analyses of the four samples you provided (2
controls and 2 treatments). Please note that the results below are not quantitative, rather
they are subjective assessments based on observations of living'versus dead algal cells_
The two control samples were rich in both motile algae (Le_ flagellates) and non-mPrile
algae (e.g. diatoms). The fust treated sample (collected in mcdiateIy after treatmeik)
showed a greater than 50% reduction in motile cells. In orher words, this implies that
about 50 % of all algae were killed_ Diatoms, being non -motile, were difficult to score z
living or dead however many showed evidence of some cell damage (Lc. cell Iysis). The
second trearment (taken after several passes) showed greater algal damage and it is
estimated that arbvnd 75% of the algae were Idllcd. Again, this assessment was based
mainly on the effect on motile algae.
I stress that these -results are ientative and arc solely based on subjective obscrvations.
However, they are encouraging and definite cell damage was evidetit in the treated
samplers. In the meandme, I am culuniflg the four samples in the laboratory to.see if the
control samples respond (i.e. grow) faster than the treated samples. If growth is more
pronatinced in the controls, it will help to substantiate the above observations. -
Sincerely yours,
Andrew Rogerson PUD

This letter is a follow up to the initial report of the results of samples taken from your OXY -Plus
SCAVENGER 2000 floating marine platform on Monday afl.ernoon .March 26, 2001.
Two untreated samples were taken. Two additional samples were taken, 1) immediately after
treatment and 2) after one pass of thirty meters and return through pass.
Nficroscopic analyses by Dr. A.ndrm Rogerson of Nova Southeastern University was performed
on cultures set up for each of the four samples. These cultures contained nutrients and were
incubated under normal environmental conditions for eight days.
Both untreated samples showed a variety of species of algae. These samples were rated as
" or 100! growth.
The sample taken immediately after treatment showed between a " ** " and" growth. This
indicates between a 25% and 50% reduction
The sample taken after one pass back and forth showed a " * " growth. This indicates a 75%
reduction.
The growth results substantiate the initial observations that indicate that the OXY -P1✓US
treatment system on your vessel is quite effective for treatmein of contaminated of surface waters.

These are the results for the operation of the Scavenger2000 Decontamination Vessel
performed on the City of Miami and Miami -Dade County waterways for the period of
October 2008 to May 2009. Funds of 200 thousand dollars originate from City of Miami
Public Works Department fiscal year 2009, and funds of 100 thousand dollars originate
from Miami -Dade County. In addition to these funds, a contribution of 10 free hours per
week is made to the City of Miami and Miami -Dade County from the Scavenger2000
owners.
Please see below a general report of amounts of debris collected, injected oxygen, and
gallons of water disinfected through our patented Oxy -Plus system.
➢ 7605 cubic feet of trash have been swept from the waters under the jurisdiction of
the City of Miami and Miami -Dade County.
100,450,000 liters of oxygen have been introduced into the area waters we have
been working. Attached you will find a brief description of the benefits of
oxygenation.
➢ 481,800,000 gallons of water disinfected through our Oxy -Plus disinfection's
system, oxidizing bacteria, viruses, algae, and some nutrients. Attached is the rate
of efficiency of the Oxy -Plus System.
The majority of the refuse we collect varies in size. The Scavenger2000 collects from
small bottle caps to dangerous navigational hazards such as 55 gallon drums, Wood
pallets, 5" wood beams, plastic sheeting, road barriers, truck bedliners, tractor tires etc.
During the last 8 months, we have noticed an increase in the amount of debris floating in
our waterways. These debris are mainly from construction sites, and are big in size. The
amount of regular trash (i.e. plastic cups, bottles, bags, etc) has also increased.
Mother Nature provides her own set of trash items. Some of these include coconuts; palm
fronds, tree limbs, small branches, leaves and sea grass which are all collected on a
regular basis. Very strong foul odors are emitted from the sea grass where bacteria and
other contaminants lodge themselves.
Approximately 1-2% of our trash includes carcasses of dogs, cats, and a few small fish
but mostly chickens, and bags of rotting meat from local fishing fleets.
We are also working closely with USCG when we find navigational hazards too large for
collection. We have found that the Coast Guard has very little resources to help discard
any navigational hazard, therefore leaving the task generally to the Scavenger2000. We
also report directly to the Department of Homeland Security in order to report any
suspicious activities under the territory of the City of Miami and Miami -Dade County.
The Scavenger's multi-purpose capabilities are a proven cost-effective addition to the
continued effort of the City of Miami to keep the waterways both clean and safe.
We have received compliments and gratitude from the following businesses along the
City of Miami Waterways including; Hurricane Cove Marina, Merril Stevens, Bassas
Cargo, Finnigans, Garcias, Bayside Marina, Davis Canal residents, Ademar canal
residents, Grove Key Marina, just to name a few.
We are proud to be part of the City of Miami and Miami -Dade County's efforts in
combating water pollution.
We have hosted many delegations from around the world to witness the Scavenger2000
in action in our waterways, and all praise the conscientiousness and foresight to keep our
waterways clean.
Please see enclosed just a few pictures of the Scavenger2000 performing its duties on the
City of Miami and Miami -Dade County waterways... A picture is worth a thousand
words... Enjoy your accomplishments...
If you would like to see additional information or pictures, please do not hesitate to
