PAC is a flocculant of new concept, the specific properties of which derive from the action of its basic active constituent, namely Poly Aluminium Chloride.
This is a polynuclear complex of polymerised hydro-aluminium ions, with the following general formula:
{ Al2 (OH)n Cl 6-n }x
This type of PAC is supplied as white powder, which facilitates the transport and storage operations and subsequent dosage of the reagent.

Application:
Poly aluminium chloride (PAC) is a kind of 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.
