ABSTRACT:
An enclosure having an inlet and an outlet for hot air, and an inlet and an outlet for waste water, contains a plurality of refractory, porous, tubular, membrane-type filters, each of which is closed at one end and connected at its other end to the waste water outlet. Hence, waste water entering through its inlet in the enclosure must pass through the walls of the filter tubes before being discharged through its outlet. During this process, any solid particles in the water become deposited on the outer surfaces of the filter tubes. After a filtering cycle is over and the waste water has been drained through its outlet, a heating means, equipped with a blower and attached to the hot-air inlet, forces heated air into the enclosure to incinerate the solids deposited on the filter tubes. Therefore, the filter tubes serve also as refractory grates to hold the sludge while it burns. After the sludge has been burned, an automatic timer switches back to the filtering cycle.
