ABSTRACT:
There is provided an improved apparatus and method for relatively low volume batch treatment and disposition of sewage or toilet wastes especially from passenger vehicles such as railway cabooses, motor houses, or other passenger-carrying vehicles. The apparatus is characterized by the ability to operate without moving parts for sterilizing, disintegrating, and discharging an aqueous sewage composition including human feces and includes an enclosed chamber having an inlet for the sewage composition at the top of the chamber, separate electrodes in the lower portion of the chamber, a standpipe having an inlet from the chamber and communicating with the upper portion of the chamber and discharging exteriorly of the chamber, and means for impressing a potential difference across the electrodes. The method is characterized by impressing a potential difference across the electrodes sufficient to effect electrolytic discharge of gas at at least one of the electrodes and impressing a current across the electrodes sufficient to cause ebullient roiling action in the composition to disintegrate the solid waste material and suspend the resulting particles in the roiling medium. This operation results in the formation of a solids-containing evolved head of lesser density above the aqueous sewage composition. The roiling action is continued whereby the head is continuously added to and expands for communication with and discharge through the standpipe.
