Activated silicic acid was compared with polyacrylamide for use as a flocculant in treating refinery wastewater. Silicic acid was obtained by treating sodium silicate with aluminum sulfate and tested by the jar-test procedure. After adding the flocculant, the oily matter content from wastewater was determined by infrared spectroscopy. Silicic acid was found to be as effective as polyacrylamide but at higher doses. The higher required dosage is offset by the fact that the material cost for silicic acid production is approximately one-tenth of that for polyacrylamide.
