Poly aluminium chloride is a new high-efficiency unorganic polymer coagulating agent, which is widely used for purify water. it is produced by advance production technology and reaction and polymerization of high quality raw materials with such characteristics as little impurity and high formula weight and effective polymerization. Application： 　　It mainly use to purify drinking water. Removal of SS, COD, BOD, get rid of turbid material to get the pure water. 　　 Advantages： 　　a)Polyaluminum Chloride is obviously effective in purifying high turbid water without adding alkaline additives. 　　b)Polyaluminum Chloride is suitable for wide range of water quality,alum flower formed is quick and big, easily settled. 　　c)Polyaluminum Chloride has fast flocculating rate, small corrsiveness and low labour intensity. Caution and storage: 　　1. Solid producing should be added after it dissolve in water and dilution ratio is generally: 2%-20%(weight percent) 　 2. The added chemical reagent is generally:1-15g/ton solid product, subject to the difference of waste water quality and turbidness, specific added quality should be decided by experimental result. 　　 3. The product must not be stored together with other chemical reagents 　　 4. Solid product should be stored in a ventilated and dry place with the storage period of two years, and availability won’t be changed after the product is affected by damp. Conclusion: 　　PAC is cheap and has good flocculation efficiency. Its water purification capacity is higher than the traditional aluminum sulfate and ferric salt inorganic coagulants.
