Aluminum Chlorohydrate (ACH)

Aluminum Chlorohydrate (ACH)

Aluminum Chlorohydrate Solution (ACH) is a highly concentrated solution characterized by having the highest aluminum concentration (23% Al2O3) and highest basicity at 83% of any commercially available aluminum based solution. The highly polymerized aluminum species in ACH have much higher cationic charges than in standard salts such as alum or aluminum chloride. The basicity also means that the effect on pH when applying ACH will be negligible.

Polyaluminum Chloride (PAC)

Polyaluminum Chloride (PAC)

The aluminum portion of the product is highly polymerized, resulting in a higher cationic charge and increased performance capability. Typically available Polyaluminum Chloride solution products have basicities ranging from 30-50%.

GPAC Series Products

GPAC Series Products

GPAC series are specially developed products using inhouse technology. GPAC includes a series of products that range in the degree of their acid neutralization, polymerization and Al2O3 concentration. These have basicity higher than 50%, giving a lower impact on the pH of the receiving water, offering rapid floc forming and settling.

Custom Specialty Blends

Custom Specialty Blends

These are customized products for the industry’s unique water treatment needs. We offer medium to high basicity products having polyelectrolytes in different ranges. We also offer producing blends as per customer specifications.
