Humic Acid Removal from Water by Poly Aluminium Chloride (PAC)

Abstract:

The removal of organic pollution humic acid from aqueous solution by inorganic flocculent poly aluminium chloride (PAC) was investigated. Flocculent was dosed under medium stirring speed of 250 r/min for 2 min, and then changed to the speed of 45 r/min for 12 minutes. And the single influential factor such as: the dosage of the flocculent, the settling time, the pH value, the initial concentration of the humic acid solution and the initial tempreture of the humic acid solution were investigated. When the initial concentration was 10.0mg/L, the pH value was 6.5 and the dosage of PAC was 28.0 mg/L, the removal rate could reach the maximum 74.2%.
