High-rate filtration (3.4 to 10 l/m/sup 2/ x s) of oily refinery wastewaters stabilized by suspended solids was evaluated to determine its effectiveness in removing oil and solids in dual-media granular beds. Results indicated that good removal of oil and solids could be achieved in the anthracite and sand beds if chemical filter aids were applied continuously to the filter influents. Cationic polyelectrolytes performed better than anionic or non-ionic polyelectrolytes or alum alone. Performance was more a function of suspended solids than of oil concentrations. Plugging usually was found in the upper layers of the anthracite and in the mixing zone between the anthracite and sand. Filter cleaning was accomplished best by air and water scour. Minimum effluent oil concentrations were limited by the oil solubility in water.
