Poly Aluminium Chloride, abbreviated as PAC, is a new type, high-effective inorganic polymer flocculam. It is the prodcut  between ALCL3 and AL(OH)3, Polymerized by building a briage through Hydroxyl. Its chemical formula is [AL2(OH)nCL6-n]m, in which   m< 10, n< 5. PAC is easily dissolved in water and has a strong bridge-building adsorption performanace . During the process of Hydrolysis, there are physialand chemical changes such as electric chemistry, condensation, adsorptionand presipitation, etc. This product is mianly used in the purification of the drinking water and the treatment of industrial sewage, such as sewage with oil, the sewage of textile , printing, papermaking mill etc, and the treatment of some special water, such as the water with radioactivity Pb++, Cr+++, poisonous heavy metal or fluorine, etc. In addition, it is also widely used in precis casting, papermaking and leathermaking, etc.
