ACH

CAS NO.:

12042-91-0

CHEMICA NAME:

Aluminum Hydroxychloride

DESCRIPTION:

BLU ACH is the most concentrated material of the PAC family, it offers the maximum alumina and basicity available in a stable solution form. As it has the highest polynuclear content and highest level of neutralization, A high quality coagulant typically used in both municipal and industrial water treatment applications to remove suspended solids and organic matter.

ADVANTAGES:

1. ACH performs at overall lower dosages compared to other metal salt coagulants due to the high Al203 content and basicity.
2. ACH effectively coagulates over a broader pH spectrum as compared to traditional metal salt solutions and PACs.
3. ACH typically has a negligible effect on the pH of treated water due to the high degree of acid neutralization.
4. Improved color and turbidity removal.

APPLICATIONS:

1. Coagulation - Drinking Water
2. Coagulation - Waste Water
3. Heavy Metals Removal
4. Phosphorus Removal
5. Sludge Thickening Conditioning and Dewatering
6. Struvite Control
7. Total Organic Carbon (TOC) Removal
8. Commercial Antiperspirants
9. Cosmetic
