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. |
