摘要： A closed loop waste treatment and water recycling system that includes a delivery system, an anoxic reactor, an aerobic digestion chamber, a filtering system, an adsorption system, a disinfecting system and a water return system. The delivery system includes one or more flush-type toilets and urinals which receive flush water from the water return system and deliver the toilet and urinal waste and flush water to the anoxic reactor. The anoxic reactor contains bacteria which utilizes organics in the toilet waste to convert oxidized nitrogen compounds, such as nitrates, to nitrogen gas, produce bicarbonates and other products. The bacteria, in accomplishing this, lower the organic load on subsequent processes. A denitrified liquid containing bicarbonates and reduced amounts of organics is transferred to the aerobic digestion chamber, which contains biologically active solids and in which organic carbon, organic nitrogen, and ammonium compounds are oxidized by bacteria to obtain a liquid product high in concentration of oxidized nitrogen compounds such as nitrates and low in soluble carbonaceous compounds. This liquid product is filtered, treated with activated carbon, disinfected, and subsequently returned to the toilets and urinals as colorless, clear and odorless flush water containing oxidized nitrogen compounds such as nitrates. The oxidized nitrogen compounds produced in the aerobic digestion chamber insure prevention of odors in the system. As a result of the effective management of nitrogen in the system, it can be made of reasonable size, undesirable odors are avoided and a desired slower buildup of solids in the system is achieved.

摘要： Apparatus is provided for treatment of a fluid by use of a membrane tube wherein a volume displacement rod is positioned longitudinally through the membrane tube to provide desired filtration conditions for removal of a permeate from the fluid, and an improved support arrangement for the rod is provided that eliminates the use of a spider or similar support structure that constitutes a fluid flow obstruction. In the disclosed embodiment, the remote ends of the rod are seated in sockets located in bends in the walls of the inlet and outlet conduits associated with the membrane tube.
