Abstract
The discharge end portion of a sewage delivery tube is surrounded by the input end portion of a conveyor pipe. A long, flat strip of consumable filter material is inserted through the annular space between them and into the conveyor pipe. Prior to this insertion, however, the filter strip is shaped and fastened into the form of a closed tube. The conveyor pipe discharges into an incinerator equipped with means for breaking the sewage sludge into burnable droplets. The conveyor pipe is supported over a liquid-collecting funnel and is perforated in the portion thereof that is over the funnel. A vibrator attached to the conveyor pipe oscillates it longitudinally; and ratchet teeth inside the conveyor pipe are oriented to cooperate with the vibrator to urge the filter-encased sludge toward the incinerator.
