Introduction • The Status of the Water Quality Control • Pollution Control Strategy Abstract One new technique was introduced preparing high-efficiency flocculation: polyaluminium chloride (PAC) with the materials of AlCl 3 ·6H 2 O. Effect of preparing conditions on quality and separation of PAC was tested. The optimal preparing method was: baking temperature 290℃; baking time 30 min; maturation time 18 h; liquids laying aside time 12 h. The crystal type and appearance of PAC was studied by
