Raw sewage drying apparatus.

摘要

A raw sewage drying apparatus is intended for use in the disposal of sewage, particlarly in portable or temporary toilets. The apparatus consists of an airtight chamber defined by casing (13) into which the sewage inlets are sealed and the contents heated either by an electromagnetic or an induction heater. The resulting vapours and ash may be passed through an array of filters (52) and over a catalyst element (53) to destroy or remove odorous components before they are exhausted to atmosphere. The use of microwave or induction heaters permits the apparatus to operate at high thermal efficiency.
