Aluminum Chlorohydrate ACH powder for Water Treatment
Product name Aluminum Chlorhydrate (ACH)/Aluminum Chloride Hydroxide
CAS Number: 12042-91-0
Molecular Formula: Al2(OH)5Cl· 2H2O
ACH is a highly polymerized solution of polyaluminum hydroxychloride. It is characterized by having the highest aluminum concentration(23% Al2O3) of any commercially available aluminum based solution. Solid product, the aluminum oxide content is 46% ~ 50%. The basicity of ACH at 83% is also the highest available for any polyaluminum based solution. Basicity refers to the degree of acid neutralization and also represents a measure of how highly polymerized the aluminum in ACH is. The highly polymerized aluminum species in ACH have much higher cationic charges than the aluminum in standard salts such as alum or aluminum chloride, and even other polyaluminum products. Therefore, ACH can offer both a higher level of performance and lower overall dosages. The high degree of acid neutralization (basicity) also means that the effect on pH when applying ACH will be negligible. ACH also effectively coagulates over a broader pH range (as high as5- 9.5) versus traditional metal salts and lower basicity PACl.

Aluminium chlohydrate Usage:
It is generally empolyed as the primary coagulant in potable water and insutraial water treatment plants, replacing the need for other coagulants such as alum, and in many cases also eliminating or at least greatly reducing the need for PH adjustment chemicals, coagulant aids. It is also used in wastewater treatment applications for TSS removal, Metals removal, COD reduction, BOD and TOC removal.
It could be used in cosmestic manufacturing.
