Our nation developed water purification chemicals as early as the 1970s. However, with the continuous improvement of our living standards, earlier water purification products and equipment have failed to keep pace with market demands. Due to the ongoing segmentation of the market, our manufacturing industry has also become increasingly specialised. Ordinary water purification products can no longer meet the diverse requirements of wastewater treatment. The emergence of new, versatile water purification chemicals is therefore of paramount importance to us. Through persistent research and innovation by our nation's technical personnel, contemporary water purification products now barely meet market requirements. Among these,
polyaluminium chloride stands as one of the more advanced water treatment agents available. How does it differ from previously used water treatment chemicals? We shall examine polyaluminium chloride produced by VICTOR Company in detail alongside other products.
Polyaluminium chloride, also known as a coagulant, etc. It is a water-soluble inorganic polymer, flocculant, and water purifier. Classified by appearance into three shades—yellow, dark brown, and dark grey—it presents as a resinous solid with strong bridging and adsorption properties. During hydrolysis, it undergoes physicochemical processes including coagulation, adsorption, and sedimentation.
Compared to other water purification agents and inorganic coagulants, polyaluminium chloride differs fundamentally. Traditional inorganic coagulants are low-molecular-weight crystalline salts, whereas polyaluminium chloride comprises structurally diverse polyhydric hydroxyl complexes. As an amorphous inorganic polymer, it exhibits unique coagulation properties distinct from conventional coagulants. Polymeric aluminium chloride produced via the calcium aluminate adjustment method achieves significantly enhanced salt and alkali degrees, with basicity increasing from 65% to 92%. Raw material costs are reduced by 10%, while operational expenses decrease by 40%, yielding substantial economic benefits in both production and application.
Polyaluminium chloride remains chemically stable at ambient temperatures and does not deteriorate during prolonged storage. While the solid form readily absorbs moisture when exposed, this does not compromise its water purification efficacy. Occasional morphological changes occur without loss of functionality, deterioration, toxicity, or harmfulness. Its operational pH range spans 4 to 14. However, the optimal treatment range is pH 6-8, which defines its applicability. It is suitable for diverse sectors, including industrial and heavily polluting industries. Furthermore, polyaluminium chloride demonstrates strong adaptability in water treatment, featuring rapid reaction, low consumption, and economical production costs. It produces large flocs with rapid settling and excellent filtration properties. This enhances equipment utilisation, strengthens purification efficacy, and improves the economic benefits for user enterprises.
