For high turbidity water and low temperature and low turbidity water disposal. Its treatment effect is better than that of alum, polyaluminium chloride, poly ferric sulfate and ferric chloride, among which, its treatment effect to low temperature an low turbidity water, may be free from alkali auxiliary or other coagulating aid, is especially obvious. It shows distinguished effect compared with other coagulant.
