ACH
Polyaluminium chloride is an efficient flocculant and water purifying agent, mainly used in water treatment. It can effectively remove suspended solids and impurities from water, improving water quality. Its hydrolyzed solution is acidic, with a fast hydrolysis rate, strong adsorption capacity, and the formed flocs are large and dense, resulting in rapid sedimentation, low effluent turbidity, good dewatering performance. In addition, polyaluminium chloride also has thermal stability and good solubility.

CHEMICA NAME:

Aluminum Hydroxychloride

DESCRIPTION:

 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:

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

APPLICATIONS:

Coagulation - Drinking WaterCoagulation - Waste WaterHeavy Metals RemovalPhosphorus RemovalSludge Thickening Conditioning and DewateringStruvite ControlTotal Organic Carbon (TOC) RemovalCommercial AntiperspirantsCosmetic
