A system for recovering fat, oil and grease (FOG) from wastewater has multiple annular flotation zones in a concentric configuration surrounding a central column to create progressively increasing surface areas for FOG and solid particles flotation, and thereby enhance FOG recovery and removal. Each flotation zone is equipped with an independent pressurized micro air and ozone bubbles distribution system. A controlled amount of ozone can be injected into the wastewater along with recirculated effluent and micro-size air bubbles. Upon the release of pressurized air-ozone-water mixture, micro-size bubbles are generated and distributed in each flotation zone to effectively float up FOG and solid particles in the wastewater stream.

A movably-connected and continuously-connected apparatus for uninterrupted high-salinity wastewater purification includes a high-salinity wastewater adsorption treatment system and a movably-connected drainage system embedded in the treatment system. The high-salinity wastewater adsorption treatment system includes four purification zone partition plates, a hollow cylindrical purification zone, a cylindrical water distribution sump located in an axial center of the purification zone, a rotating shaft, a motor, a fixed support and a water tank; the four purification zone partition plates include a first partition plate forming an angle of 135° with a horizontal direction from left to right, a second partition plate forming an angle of 45° with the horizontal direction from left to right, a third partition plate forming an angle of 135° with a vertical direction from bottom to top and a fourth partition plate forming an angle of 135° with the vertical direction from bottom to top.

A water treatment system, such as a water softening system, having a water treatment tank with at least one distributor plate mounted inside to support filter media and/or ion exchange resin. The water treatment system is designed to treat hard water with a packed ion-exchange filter media and has a distributor plate design for facilitating the ion-exchange within a water softener resin bed, as well as facilitating the regeneration of the resin bed. The distributor plate presents cavities to the topside for entrapping filter media, and the cavities have narrow slits located at the base for allowing fluid to pass. A method for assembling the water treatment tank and supporting inserted distributor plate is shown. The distributor plate rest on and is supported by a domed-shaped structure that can be placed in the bottom portion of the water treatment vessel.

An improved system and method for extracting volatile organic compounds (VOCs) such as ammonia from leachate water. Uses specialized pressurization of leachate water to extract VOCs which may then be recaptured in more highly concentrated water to reduce overall volume of contaminated water.

An exemplary, nonlimiting embodiment of the present invention relates to a water treatment and filtration system for reducing the concentration disinfection byproducts within drinking water treated by municipal drinking water treatment plants. This water treatment and filtration system reduces the concentration of disinfection byproducts, which may include trihalomethanes (THM) and haloacetic acids (HAA5), in drinking water using a clever sequencing of treatment techniques that intentionally promote formation of the disinfectant byproducts prior to filtration to effectively remove disinfection byproduct precursors and prevent subsequent formation of disinfection byproducts downstream during distribution. Moreover, this water treatment and filtration system can be retrofitted to a variety of municipal drinking water treatment plants and is designed to easily scale if demand for drinking water within the municipality increases.

A laboratory water generation and distribution system capable of distributing laboratory water at different temperatures is disclosed. A laboratory water generation section is configured to receive potable water and treat the potable water to generate laboratory water. A laboratory water distribution section comprises a laboratory water storage tank and a main distribution loop fluidly communicating with the laboratory water storage tank to receive the laboratory water therefrom. The laboratory water distribution section further comprises a sub distribution loop operatively connected to the main distribution loop via a valve to receive the laboratory water therefrom. The sub distribution loop returns to the main distribution loop and dispenses the laboratory water to the main distribution loop.

A water treatment system having a base assembly and a treatment assembly. The treatment assembly of the system may be configured to filter particulates from water. The base assembly may include a UV reactor operable to disinfect water for consumption.

A wastewater management system has a container with the first chamber and a second chamber therein, a diverter valve having an inlet and a first outlet, a holding tank interconnected to the first outlet of the diverter valve, and a controller connected to the diverter valve so as to move the diverter valve to the first position. The first outlet is directed to the first chamber. The inlet of the diverter valve is adapted to receive wastewater from a location remote from the container. The inlet is connected to the first outlet in the first position. The diverter valve can be a three-way valve having a first outlet directed to the first chamber and a second outlet directed to a second chamber. The controller moves the diverter valve between first and second outlets.

Movable thick dehydration device and method for eluent sediment from medium- and low-concentration ammonia nitrogen are provided. The device integrates the existing eluent preparing mechanism, a transferring mechanism, pumping mechanisms, a transport vehicle, an automatic controlling system, an eluent collecting pool, primary and secondary sedimentation pools, and primary and secondary processing units. After post-treatment and recovery of eluent waste from rare earth mines, ammonia nitrogen and rare earth heavy metals in the eluent of rare earth mines can be recovered and disposed, and 90% of ammonia nitrogen and over 95% of rare earth in the eluent can be recycled. The device is movable and automated, and therefore suitable for environmental treatment of closed rare earth mines with residual ammonia nitrogen. Meanwhile, it is beneficial to reduce investment costs of capital construction, disposal site restoration of environmental treatment of rare earth mines with residual ammonia nitrogen.

A method and apparatus for conditioning the settled solids in the bottom of a wastewater filtration tank to reduce the acidification of the sludge and prevent the excessive growth of undesirable biological growth.
