Treatment of Succade Wastewater with the Coagulating Agents PAC and Ferrous Sulfate
Succade wastewater, which was produced in manufacturing process, was treated with two kinds of coagulating agents PAC and ferrous sulfate. The influences of pH, concentration of coagulating agent on COD value, turbidity have been studied. The results of the experiments have shown that for ferrous sulfate, there is an obvious positive correlation, but no significant relation with turbidity removal rate was presented in the statistics; As for PAC, the turbidity declined significantly as PAC dosage increases, only when pH=5 that COD removal rate shows a clear positive correlation with PAC dosage.
