Polyaluminiumchlorid

Poly Aluminum Chloride Brief Introduction 1. PAC is a kind of inorganic macromolecular coagulant. Through the hydroxyl ion's bridging function and the multiple-valence positive ion's polymerization,the inorganic macromolecular water-treatment medicament is formed which has high molecular weight and electric charge. 2.The quality of purified water is better than that of water treated with other inorganic coagulant such as aluminum sulfate while the cost of purification ofPAC is lower.inorganic concrete agents such as aluminum sulfate while the costof purification is lower than those using other inorganic concrete agents. 3. Floccules form and subside faster and treatment capacity is bigger than traditional products like aluminum sulfate.Quality Index Item Solid LiquidAl2O3,% min. 300 10.0Saltness, % 40.0-90.0 40.0-85.0Water-insoluble % max -- 1.15pH(1% w/v) 3.5-5.0 3.5-5.0N ( as NH3),% max. 0.01 0.01As,%max. 0.0001 0.0005Cr+6,%max. 0.0005 0.0005Hg,%max. 0.00001 0.00001Pb,%max. 0.0005 0.0001Cd,%max. 0.0001 0.0001Note:the product can offered upon the customer's request.Mainly Usage 1 Purification of water from river and reservoir or underground water for urban water supply. 2.Purification of water for industrial supply. 3.Urban sewage treatment and mud treatment. 4.Raw material of cosmetics. 5.catalyst carrier. 6.Coating material in paper-making. 7.The dosage differs as per the quality of raw water.
