Abstract

Abstract A water closet and digester are parts of a sewage disposal unit that includes filter beds, tanks for bacterial action, and a recirculating flushing water line. The solid wastes can be disintegrated by a mascerator. In one embodiment the mascerator applies pressure to the waste by using motor driven rollers having flexible surfaces.
