Organic compounds present in wastewater can be removed by established biological processes or by the recently developed physicochemical process wherein organics in the sewage are adsorbed on activated carbon after coagulation and sand filtration.

In both adsorption and bio-oxidation, residuals have been observed. Theoretically, a combination of both processes should remove these residuals, but to date, evidence is lacking to support this hypothesis. This study evaluated biological and adsorption residuals singly and in combination.
