ABSTRACT:
A process and apparatus for the treatment of septage, particularly grease trap waste, is disclosed. The inventive process will convert the septage into Biosolids (sludge) and water dischargeable to the environment. The treated septage achieves pathogen reduction, and reduced vector attraction. Treatment of septage by pasteurization causes the destruction of harmful pathogens. Pasteurization of septage having high water content provides for even temperature elevation and distribution of heat within the thermal mass of the septage allowing for consistent pathogen destruction. An alkaline compound is utilized to form a filter cake from the solids fraction of the pasteurized septage preventing vector attraction, while producing a beneficial bio-solid. The liquid fraction of the septage is treated by biological process allowing for its discharge into the environment.
