Introduction:

Aluminium chlorohydrate is a group of specific aluminium salts having the general formula AlnCl(3n-m)(OH)m. It is used in deodorants and antiperspirants and as a coagulant in water purification.

in water purification, this compound is preferred in some cases because of its high charge, which makes it more effective at destabilizing and removing suspended materials than other aluminium salts such as aluminium sulfate, aluminium chloride and various forms of polyaluminium chloride and polyaluminium chlorisulfate, in which the aluminium structure results in a lower net charge than aluminium chlorohydrate. Further, the high degree of neutralization of the HCl results in minimal impact on treated water pH when compared to other aluminium and iron salts.

the advantage of ACH:

1),It is accepted as the replaced product of PAC (Polyaluminum Chloride) used for the water treatment,to reach the same result when treating water.

2),It is less consume quantity than PAC, very friendly to environment . 

3),It can lead to quick formation of flock with big size and rapid precipitation.

4),It has widerange adaptability to thewaters at different temperatures and a good solubility.

5),the solution of ACH is slightly corrosive and suitable for the automatic dosing and convenient for eperation.

Usage:

1) Urban drinking water treatment;

2) the urban sewage and industrial wastewater treatment;

3) Paper industry;

4) Cosmetic Raw Materials.
