Poly-Aluminium Chloride(PAC) is a kind of innocuous, insipidness and easy dissolve in water with appearance of white or light yellow or yellow colour lipidic from liquid and fine resin solid powder, solid product is easy adsorb damp when exposed in the air.

PAC is composed with a series of different polymerizing power of abio-macromolecule compound, it occupying best configuration distribution, the main content is which has high electricity polymerization link distribution figure provided with Keggin configuration, due to it have high electric neutralization and united function to cooloid and fine substance in the water, it mightly wipe off micro-poison and heavy metal ion,PAC has stable capability and configuration character
