A sewage treatment apparatus having an input tank with mixing and screen filtering means for receiving liquid waste such as raw sewage. The level of liquid waste in the input tank controls a timer which activates a valve to release the screened sewage into a filter centrifuge for rapidly separating liquids and solids in the liquid waste. The solids separated are burned and vacuumed from the filter centrifuge following filtering of the liquid through a filter medium located in the centrifuge. A high speed perforated drum centrifuge is lined with a filter material such as sand and the drum may have vanes on its periphery to form an impeller to act in conjunction with a diffuser casing to form a centrifugal pump integral with the filter.
