In Septage Treatment method, the collected septage is to be processed in treatment plants that are strategically located in their service area. The treatment is a physical-biological-chemical process which consists of coagulation, gravity solid-liquid separation and activated sludge. The liquid output is discharged to receiving waterways while the sludge cake output is disposed to existing sanitary landfills. Dewatering is the method by which the collected septage is subjected to a mechanical solid-liquid separation at either a transfer station or at a mobile dewatering device.
