The self-filtration system includes a self-cleaning filter used in tandem with an adapter, a decanter, and a series of hoses.

  • Patent number: 9126854
    Abstract: An apparatus adapted to treat at least one target compound comprising a housing through which fluid may pass; a receiving zone defined within the housing; disposed after the receiving zone within the housing, a destruction zone in which an aqueous solution containing at least one target compound is exposed to a destruction agent, the destruction agent adapted to convert the target compound into destruction byproducts; disposed after the destruction zone, a filtration zone containing a filtration agent adapted to remove the destruction byproducts from the solution; liquid disposal means for receiving solution from the filtration zone; and solid disposal means for receiving solids from the filtration zone, whereby, the target compound is first converted to byproducts, then the byproducts are filtered out of the solution, preventing target compounds from entering wastewater systems and ultimately re-entering the water supply.

  • Publication number: 20150136667
    Abstract: A water treatment system including a media filter having a filter chamber with a volume to accommodate filter media and a sludge outlet and a charge chamber for storing air. The charge chamber is fluidly connected to the filter chamber and has: (i) an air outlet for admitting air into the filter chamber; and (ii) an air inlet. The system also includes a trigger for selectively allowing the passage of air from the charge chamber air outlet into the filter chamber upon reaching a trigger release point and a sludge concentration/storage volume having at least one wall extending upward to form an upper opening. This wall has a height substantially above the trigger release point and substantially isolates the sludge volume from the charge chamber, except for the upper opening. Finally, an inlet to the sludge volume is at a height which allows pressure within the media filter during a filtration stage to move water above the wall height and into the sludge volume.

  • Patent number: 8986538
    Abstract: A cutting fluid filtering device having a filter washing function drives a pump to supply a cutting fluid to a filter when the fluid level of a tank that stores the cutting fluid filtered by the filter becomes equal to or lower than a predetermined height. In addition, the cutting fluid filtering device issues an instruction to execute washing of the filter when the operation times of the pump are totalized and the total value becomes equal to or longer than a preset washing operation interval time of the filter.

  • Patent number: 8961782
    Abstract: Grey water is conveyed to a tank, passed through filters, and pumped to an irrigation system. A floating spray component is provided in the tank to automatically backwash the filters to prevent clogging, moving up and down as the level of water in the tank changes. The filters can be cylindrical and oriented vertically, and a removable, internal filter cartridge can mount the filters. The filters can be accessed through a top, above ground cap, and the carriage can be removed for access to other parts by removing a larger lid.

  • Patent number: 8955690
    Abstract: An unclogging filter apparatus has an irrigation outlet and a flushing outlet. A filtering element moves between at least an operational position and a flushing position. When the filtering element is in the operational position substantially all of the fluid flowing into the apparatus is directed out the irrigation outlet, while the filtering element is disposed for removing a particle from the fluid flowing into the apparatus. When the filtering element is in the flushing position, the filtering element is disposed for flushing the particle out the flushing outlet.

  • Patent number: 8889007
    Abstract: The present invention is a wastewater treatment system utilizing a recirculating filter system comprising sand, gravel, or synthetic media. Septic effluent is continuously, or approximately continuously, dosed under pressure to the treatment media through pressure compensating drip irrigation emitters. The system comprises a commonly known septic tank and recirculation tank. Septic tank effluent is collected in the recirculation tank, from which it is continually dosed by means of a pump to the top of the treatment media of the recirculating filter through pressure compensating drip emitters. Continuous dosing of diluted residential septic tank effluent through drip irrigation emitters provides a slow consistent application of liquid rich in organic material and pathogens over the treatment media. The treated effluent is then recirculated if water is low or went to final disposal.
