Highly effective classification and use of aluminum chloride Clearly visible as a representative of water treatment materials Poly aluminum chloride is an efficient low-cost water purification materials, inorganic polymer coagulant, also referred to as aluminum, abbreviated PAC, Due to the bridging effect of hydroxyl ions and the polymerization of polyvalent anions, higher molecular weight and higher charge inorganic polymeric water treatment chemicals are produced. In morphology can be divided into two kinds of solid and liquid. Solid by color is divided into different sepia, beige, golden yellow and white, the liquid can be rendered colorless and transparent, light yellow, light yellow to brown. Different colors of aluminum chloride in the application and production technology is also a big difference. Polyaluminium chloride main features: 1, floc forming fast, good activity, good filtering. 2, without adding alkaline additives, such as case of deliquescence, its effect unchanged. 3, to adapt to PH wide, strong adaptability, wide range of uses. 4, less salt water treatment. 5, to remove heavy metals and radioactive substances on the water pollution. 6, the active ingredient is high, easy to store, transport.
