1.1.3.4 Water Recovery/Filtration System Operation: Once the 6 GPM flow enters the filtration system in first shall enter an oil coalescing tank. As the water flows it shall be forced up through an oil coalescing assembly, which removes oil from the water. A constant flow of air/ozonation shall be injected into the water stream as it enters the tank creating a diffused air effect to enhance oil coalescing and separation and treat the water to reduce C.O.D.’s and B.O.D’s to eliminate odor without the use of chemicals and to eliminate viruses and bacteria. When the water flow leaves this treatment tank it shall enter a second treatment tank and flow down through another coalescing assembly to remove more oil. At this point the partially cleaned water shall be pumped through a 40 micron cyclone separator to remove particulate mater that is heavier than water down to 40 micron in size. The water shall next be passed through an oil polishing filter containing a cleanable oleophilic foam (cellofoam) containing millions of oil adsorbing polyethylene cells to remove trace emulsified oil from the water. The cellofaom filter material shall be housed in a multi chamber stainless steel housing and shall be easy to disassemble and clean. The cellofoam filter shall be non-channeling. If the pressure washer does not require water, the water shall be continuously recirculated back to the first tank for re-processing and further filtering and cleaning.

1.1.3.5.8 Oil Separator (Coalescing and Diffused Air): The oil separator shall be designed to meet the basic API design criteria and improve on it by further disbursing the effluent equally over a series of first stage corrugations, which through the resulting tumbling action they induce shall cause enough agitation to force the larger globules of lighter-than-water oil to rise more quickly to the surface. the 1" maximum spacing of the second stage corrugated parallel plates must assure that rising oil droplets have only a very short distance to rise to encounter an oleophilic surface so they can coalesce into sheets of oil and then slide to the surface. The surface area and size of the separator must be such that it assures laminar flow so as the coalesced sheets of oil creep upward to form an oil slick. An opening shall be provided for all debris and sludge that might tend to settle in the chamber to effectively channel it to the hopper bottom of the supporting holding tank near the purge valve for easy removal during a purge cycle. The coalescing action shall be enhanced by the constant injection of diffused air of ozone to assist in facilitating the rising action of free oils and detergents and through the aeration process help eliminate B.O.D.’s and C.O.D.’s and reduce odor and algae potentials.

1.1.3.5.9 Oil Adsorption Filter (Cellofoam): The oil filter shall be designed such that all the water passing through it must flow a specific path through the oleophilic adsorption material. As the remaining free oil in the water passes through the system, it is collected by the oleophilic attraction of the cellofoam and remains there until cleaning. The oil filter container shall be made of a corrosion resistant stainless steel 50 PSI rated pressure vessel, have an easily removal cover and be readily accessible for removal of the oil adsorbing cellofoam blocks for replacement or cleaning as necessary to maintain oil-free water. The oil adsorption filter shall be designed such that the flow through it is laminar, insuring there is a minimal amount of turbulence to allow the oil coming in contact with the oleophilic cellofoam to be coalesced and retained within the cellofoam material. The cellofoam material shall be manufactured of a resilient, tough material inert to the chemicals being used and be cleanable and reusable.

1.1.3.6 Water Recovery System Performance Specifications: Typically the wash water recovery system should be capable of reducing oil and greases to below 5 PPM, drop c.o.d. and B.O.D.’s to acceptable sanitary sewer discharge levels, reduce suspended solids below 10 micron in size, remove a high percentage of heavy metals and reduce odors caused by bacteria, sulfides and organics. The system shall not be required to produce "potable water".

1.1.4 Vacuum Boom Water Pick-Up System: The vacuum boom water pick-up system shall provide a means of damming off the flow of wash water through the use a boom and a means for recovering the water through a vacuum suction process and transferring the dirty wash water to a holding tank mounted on the trailer. The boom shall be constructed with a flexible side-wall and manufactured of a fabric backed closed cell foam material that will not absorb liquids. The side-wall shall be supported and reinforced with molded plastic ABS plastic ribs. The bottom edges of the side-wall shall be designed to seal tightly against any hard surface as a vacuum is created inside a semi-circular hollow tube. Port openings shall be provided along the bottom edges on one side only to inhale wastewater into the hollow boom (tube) to be conveyed by airflow through the tube to a wet vacuum recovery tank. The basic boom shall be 20’ in length and shall come in 5’ sections and shall be open at both ends. Vacuum hoses from the wet vacuum recovery unit shall be connected to the end cap.
