Abstract: The present invention provides a process for treating vegetable oil refinery effluent (VORE), the process including the steps of separating and removing fatty matters from VORE using a fat trap (1) at a pH level of between 4 to 7 and at a temperature range of between 40°C to 60°C, flocculating (2) the effluent substantially free of fat using at least one polymer, removing suspended solids as contained in the flocculated effluent by dissolved air floatation or induced air floatation (3), mixing the partially treated effluent with at least one electrolyte (4) at pH level 6 and removing precipitate and/or suspended solids from the treated effluent using a filtration means (6), wherein the precipitate and/or suspended solids are metal oxides such as iron oxide, calcium oxide, magnesium oxide or sodium oxide to produce a fully treated effluent with COD levels

Abstract: The present invention provides a process for treating palm oil mill effluent (POME), the process iacluding the steps of cooling the POME (1) in a cooling pond from a temperature range of between 60°C to 90°C to a temperature range of between 20°C to 60°C, flocculating suspended solids using at least one polymer or flocculating and coagulating suspended solids using at least one polymer and coagulants (2) to produce flocculated suspended solids or flocculated and coagulated suspended solids in the cooled POME, dewatering the flocculated suspended solids (3) to remove the flocculated suspended solids, clarifying the dewatered POME (4) to remove sludge from the dewatered POME, removing the coagulated suspended solids (5) from the dewatered POME, mixing the partially treated POME with at least one electrolyte (6) to produce ionised partially treated POME, delivering the ionised partially treated POME to an electro-oxidation ceII (7) to produce a treated POME or an active oxidizing agent and removing precipitate and/or suspended solids from the treated POME (8).
