Abstract:The removal of arsenic in micro-polluted water by enhanced coagulation was studied with poly ferric sulfate (PFS) and poly aluminum chloride (PAC). The effects of pH, dosage of coagulant and oxidant, initial concentration of arsenic and initial turbidity on the removal efficiency of arsenic were discussed. The removal rate of arsenic treated with PFS was higher than that of with PAC. Under the condition of pH6~8 and PFS 0.078mmol/L, the residual concentration of arsenic in post-treated water was lower than 0.01 mg/L for raw water with initial concentration of arsenic 0.1 mg/L.
