                                       Gereral Introduction:
Polyaluminium Chloride, short for PAC, it is a kind of high-effective inorganic macromolecule flocculant. Through the hydroxyl ion bridging function and the polyvalent anion polymeric function, it produces large molecular and high electricity inorganic macromolecule. It adapts a wide PH range of 5.0~9.0, and the best is between 6.5~7.6.

The PAC-SW series is a sewage (waste water) grade Polyaluminium Chloride, its solid appearance is Yellow or Red brown powder, it is a high-effective inorganic macromolecule flocculant. Its molecule is larger than usual inorganic flocculant. It is a subtance that between AL2OH3 and aluminium hydroxide, easy to be dissolved, the water solution is a kind of hydrolyzate, the colloid is with electric charge and could act hydroxylion bridging function to absorb the suspended sbustance.


Application:
1)     As an important coagulating agent, t is widely used in the Purification of the industry water, sewage, metallurgical industry, paper-making industry, PCB-manufactuering industry, leather-making industry, textile printing industry, pharmaceuticals industry electroplating industry etc.

2)     It is wilde used especially the disposal of various kinds of polluted water(waste water) , especially have very well effect for Purification of metal waste water with Fe, Mn, Cr, Pb etc and water water with oil. Also it have the function of decoloring and disposal of COD.
