The application of physicochemical treatment (PCT) to an overloaded sewage‐treatment works is described. Two methods were evaluated: (i) the ‘Clariflow’system marketed by Energy and Waste Systems Ltd, and (ii) an ‘in‐house’system of dosing chemicals into existing tanks. Both methods increased the efficiency of primary sedimentation, thereby reducing the organic load applied to biological filters and improving final effluent quality. Some indication of the cost‐benefit relationships was obtained.
