摘要： A device for filtering and disinfecting a fluid, such as waste water, is provided. The device includes a housing having an interior and a fluid inlet conduit in flow communication with the interior of the housing. An ozone source is in flow communication with the interior of the housing. Additionally, a method of filtering and disinfecting a fluid is provided. Filter media is introduced into a housing to form a filter bed. The fluid to be filtered is directed into the housing such that the fluid flows through the filter media to form a filtrate. Ozone is directed into the housing such that the ozone contacts and disinfects the filter media and the filtrate.

摘要： A drainless reverse osmosis (RO) water purification system provides relatively pure water for on-demand dispensing, while recycling brine to a domestic hot water system. The drainless purification system includes a pre-filter catalyst cartridge for removing chlorine-based contaminants from a tap water supply upstream from an RO membrane. The catalyst is regularly refreshed by a high through-flow of water to a conventional cold water dispense faucet, thereby significantly prolonging the service life of the RO membrane. The RO membrane is incorporated into a multi-cartridge unit adapted for facilitated slide-out removal and replacement as needed. A control valve recycles brine from the RO membrane to the hot water system during pure water production, and recirculates tap water through the RO membrane when a pure water reservoir is substantially filled. The multi-cartridge unit may further include an air filtration system for providing a flow of filtered air.

摘要： The present invention relates to a sewage disposal method employing a filter media and an apparatus for carrying out the same intended for the effective prevention of the clogging of the filter media. Sewage currents are generated in a circulation passage means defined in a septic tank by a sewage current generating means to circulate the filter media regularly and continuously through the circulation passage means by the sewage currents. Sludge can be removed from the filter media by regularly circulating the filter media without dispersing the sludge in the septic tank.

摘要： A piezoelectric deionization system uses a piezoid bed made up of multiple piezoids for deionization of a working fluid containing charged particles, ions, and/or ionic complexes. The working fluid may be salt water in various embodiments. A uniaxial compressive force is applied to the piezoid bed causing a piezoelectric effect in the piezoids, resulting in a piezoelectric field generated by each particle, which attracts charged particles, ions, and/or ionic complexes contained in the working fluid. The piezoid bed is contained in a closed chamber to which the uniaxial compressive force is applied. Monocrystalline quartz particles or another suitable piezoid, natural or synthetic, may be used. A fluid is used to purge the piezoid bed of charged particles, ions, and/or ionic complexes after the piezoid bed becomes saturated through use. The working fluid may be used to purge the piezoid.

摘要： A floating media filter including a filter housing having an influent inlet and an effluent outlet. A floating media is positioned in the housing and forms a static media bed when the filter is in a filtration stage. A diffuser trough is positioned in the filter housing such that the lower surface of the media bed, when the filter is in the filtration stage, is below the upper edge of the diffuser trough. A backwashing mechanism causes dispersion of the media bed during the backwashing stage.

摘要： A water restoration system is presented. The system includes a filtration chamber disposed proximate to or within a water basin, such as a watershed basin, to continuously filter contaminants from the water basin without relying on a rain event. The filtration chamber includes a reaction chamber and an aeration and mixing chamber, such that the water removed from the basin interacts with filtration media within the reaction chamber, and such that the filtration media mixes with the water (while the water is aerated) within the aeration and mixing chamber. As a result, water from the basin is continuously filtered through the water restoration system to reduce the concentration of contaminants, such as phosphorus and nitrogen, from the water basin.

摘要： A floating media filter including a filter housing with an influent conduit extending into the filter housing, the influent conduit having at least one outflow aperture positioned below an effluent outlet of the filter housing. A floating media is positioned in the filter housing and forms a media bed when the filter is in a filtration stage, the media bed having a lower surface and an upper surface defining a filtration zone between the lower and upper media bed surfaces during the filtration stage. A diffuser trough is positioned in the filter housing such that (i) the lower surface of the media bed, when the filter is in the filtration stage, is below an upper edge of the diffuser trough, and (ii) the outflow aperture of the influent conduit is positioned sufficiently close to a surface of the diffuser trough such that influent flow, during the filtration stage, is initially directed against and/or along the surface of the diffuser trough, and then redirected in a path into the media bed. Finally, the media filter includes a backwashing mechanism causing (i) lowering of the upper surface of the media bed to a point below the upper edge of the diffuser trough, and (ii) creation of an air space in a substantial portion of the filtration zone.
