Advanced treatment of liquid swine manure using physico-chemical treatment

▶ Swine manure was treated by coagulation/flocculation followed by an oxidation step. ▶ This physicochemical treatment removed suspended solids, total organic carbon and nutrients. ▶ Complete total coliforms reduction was achieved in diluted swine manure samples. ▶ Levels of ammonia, hydrogen sulphide, and carbon dioxide gases were reduced. ▶ Reduced sludge production was achieved at natural swine manure pH.
