The present invention is directed to the removal of one or more selected target materials, in particular a physiologically active compound contaminant, from various streams using a rare earth fixing agent.

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.

The invention is a high-salt waste water air powered low temperature evaporating device and method of use. A tray is mounted on a lifting platform; an air inlet and a water inlet are on the tray. Air distributing pipes are arranged at the center of the nested column tubes (33). A groove (4) is installed at the top of the tray, and mounting points are accompanied by multiple nested column tubes (33). The nested column tubes (33) are connected with the air inlet. An atomizer is arranged inside the air distributing pipes; and the atomizer is connected with the water distributing pipes. Using air power evaporates concentrated waste water multiple times so that the salt in the wastewater reaches saturated concentration, and therefore, the wastewater temperature is reduced, salt is crystallized and separated out, liquid is continuously evaporated, and the wastewater can be completely treated.

A waste peptone disposal system is provided, the system utilizing steam to increase the temperature of the waste peptone and provide active homogenous mixing inside a thermally insulated tank. Steam is introduced through a steam sparging system and directly applied to the waste peptone to reduce noxiousness, allowing the facility to dispose of the processed waste peptone through a wastewater system.

A three-dimensional photo/electrodialysis unit includes four compartments. A first compartment holds a three-dimensional electrode and a group of one or more electrochemically active redox species. A first electroactive cation selective membrane couples the first compartment to a second compartment that provides a first feedstock. An electroactive anion selective membrane couples the second compartment to a third compartment that provides a second feedstock. And a second electroactive cation selective membrane couples the third compartment to a fourth compartment

The invention discloses a fast biofilm formation method for an organic filler during treatment of sewage with a low C/N ratio, and belongs to the field of biofilm process for sewage treatment. The invention improves the effect of biofilm culturing by changing the micro-interface acting force of the filler and accelerating the attachment and colonization of microorganisms on the filler through increase of bacterial quorum-sensing molecules. As compared with a conventional biofilm culturing method, in the invention the biofilm culturing is rapid and operated conveniently, has strong practicality, and is a fast biofilm formation method for an organic filler, which is adapted for treatment of sewage with a low C/N ratio under an aerobic, anoxic or anaerobic condition.
