T he variables polyepicholorohydrin-dim ethylam ine (EPI-D M A ) dose, polym eric alum inum ferric chloride (PA FC) dose and pH were selected as the factors in the RSM to investigate their individual and interaction effects on the response values, HPAM and COD rem oval efficiencies. The results showed that HPAM and COD removal efficiencies o f 95.4 % and 85.7 % respectively could be reached using 0.65 mg/L EPI-D M A , 924 m g/L PA FC and pH=5.51.
