A cleaning system includes a planar material beneath a soiled grow table. The planar material is non-porous except for a drain. Above the planar material is a plate layer including at least two layers of runners arranged in a grid where each successive layer is offset at an angle with respect to the grid of a previous layer. The plate layer rests upon the non-porous material. An upper layer covers the plate layer and has a plurality of holes. A roller table is provided for slideably supporting the grow table. Nozzles are positioned over the grow table and is/are interfaced to a pump for receiving and spraying liquid from the pump downwardly towards the grow table. The liquid and impurities (e.g., soil, leaves) fall to the upper layer and through the plurality of holes for cleaning and filtering the liquid before the liquid is returned to the pump.

A system for watercraft decontamination includes a substantially water-tight vessel sized and shaped to accommodate a watercraft, the vessel containing water and including a structure adapted to facilitate disposition of the watercraft in the vessel such that the a rear portion and transom of the watercraft that are normally submerged in watercraft use are submerged in the water. The system further includes a water heating system operatively connected to the substantially water-tight vessel, so as to heat the water from the vessel, and a water circulation system operatively connected to the substantially water-tight vessel and the water heating system and adapted to circulate water between the water heating system and the substantially water-tight vessel. The water heating system is sized and configured to maintain a temperature of the water in the substantially water-tight vessel at a temperature of between approximately 100° Fahrenheit (38° Celsius) and approximately 110° Fahrenheit (43 degrees Celsius).

An absorbent belt according to an embodiment is for absorbing an oil contained in a cleaning liquid, and the absorbent belt includes a sponge member coated with dopamine (DA) formed by immersing a sponge in a solution mixed with the dopamine in a preset range of 1 g/L or more and 16 g/L or less.

A Vehicle Wash Reverse Osmosis System is provided,

A vehicle wash system is provided that includes an oxidizer system and a filter system.

An apparatus for collection and disposal of fats, oil and grease that includes a fabric container having at least one open end, a biogradable material capable of absorbing a large quantity of fats, oil and grease positioned in the container through the open end, the container and biogradable material adapted for being placed in a source of fats, oil and/or grease for absorbing the fats, oil and/or grease for removal from the source and for transport to a location for processing.

A device, system, and method for purifying a fluid is provided. The fluid purification device includes a tank, a cover and a release assembly. The tank having a hollow interior. The cover is sealingly coupled to the tank. The release assembly is pivotally coupled to the cover, the release assembly having a relief valve fluidly coupled to the hollow interior, the release assembly being movable between a first position and a second position, the relief valve being movable between an operating position, a released position and a non-operational position.

A method of forming a biofuel by capturing fats, oils, and/or greases in a grease trap is described. The method includes adding an absorbent material to a grease trap to absorb fats, oil, and/or greases, forming a biofuel by absorbing the fats, oils, and/or greases over time, removing the formed biofuel from the grease trap, and optionally transporting the biofuel for storage and/or incineration. The absorbent material, which may be stored in a porous fabric container in the form of a tube or a mat, includes: sphagnum peat, mushroom compost, orange peels, and/or polypropylene.

An apparatus for collection and disposal of fats, oil and grease that includes a fabric container having at least one open end, a biogradable material capable of absorbing a large quantity of fats, oil and grease positioned in the container through the open end, the container and biogradable material adapted for being placed in a source of fats, oil and/or grease for absorbing the fats, oil and/or grease for removal from the source and for transport to a location for processing.

Wastewater treatment plants and processes for treating wastewater are described. The wastewater treatment plant utilizes channel plug flow dynamics with attached growth media and pure oxygen or mixtures of pure oxygen and compressed air.
