Abstract: A bioprocess comprises regulating pH of trade effluent wastewater, adding and mixing a first bio-additive, adding and mixing a flocculant/coagulant, filtering through a filter device, adding, mixing of a second bio-additive with aeration, and adding and mixing of a third bio-additive with aeration. Treatment can be discontinued or continued by adding and mixing of hydrogen peroxide with aeration, and optionally exposing treated effluent to UV disinfectant. The treated effluent can be recycled or disposed. Compositions of bio-additives 1, 2 and 3 comprise a group of highly selective and effective microorganisms and enzymes that are immobilized on carrier support matrices from a group of alginate, chitosan, polyacrylamides, k-carrageenan and agarose.
