Use of Bio-Amp, a commercial bio-additive for the treatment of grease trap wastewater containing fat, oil, and grease

► Grease trap wastewater was studied with and without Bio-Amp treatment. ► Bio-Amp can reduce FOG deposit formation and thus alleviate sewer line blockage. ► Bio-Amp can reduce COD and nutrients loadings to the treatment plant. ► Bio-Amp can increase rbCOD fractions and potentially enhance Bio-P removal.
