ABSTRACT:
A packaged wastewater treatment unit has a compact configuration into which all subcomponents may be integrally molded. The compactness of the unit results from the arrangement of the subcomponents within the unit. In one embodiment, a clarifying unit and a basin into which a biological digester is mounted are formed within the top surface of a tank. The interior of the tank contains a collecting compartment separated from a secondary compartment by a baffle. In another embodiment, the housing of a disinfecting unit, such as an ultraviolet or chlorination unit, is also formed within the top surface of the packaged system.A method for treating wastewater includes using a single integrated unit to feed an effluent stream to a collection tank and then transport it to a biological digester, clarifying unit, and disinfecting unit. The effluent stream may be transported through the unit by a series of pumps and spillways. Optionally, the output stream may also be subjected to a sand filtration unit.
