ABSTRACT:
Sewage water with entrained solids as an effluent is fed into the trough bottom shaped process tank that is a totally enclosed tank other than for inlets and outlets therefore. The system disposes of water from sewage effluents and also residual solids thereof and is fed sewage to a controlled depth in a tank trough with high temperatures used to sterilize the effluent. A two-speed motor driven mixer driven at low speed continually mixes and blend the sewage effluent at the same time air from a blower is bubbled through the mixture. Heat is added to increase water vapor saturation capability of the air flow through the system. The air/vapor mixture flows through a recuperative heat exchanger supported within the tank above the surface of sewage effluent contained therein, absorbing heat with flow, through a catalyst bed in a chamber with circulation through the heat exchanger and on out an exhaust vent with impurities oxidized and vented with air flow. Heating elements subject to power control heat the tank and the heat exchanger.
