Polyaluminum chloride effect Poly aluminum chloride is a kind of new and efficient inorganic polymer coagulant commonly used in the world. The general chemical formula is [Al2 (OH) nCl6-n] m, mainly through compressing double layers, Neutralization, adsorption bridging, sediment net arrest and other mechanisms of action, so fine particulates and colloidal particles in water detachment, aggregation, flocculation, coagulation, sedimentation to achieve purification effect. Is widely used in water plants, power plants (thermal power plants) and other types of factories water and industrial water purification and various types of factories such as chemical plants, smelters, petrochemical plants, paper mills, printing and dyeing plants, dyeing plants and other industrial wastewater treatment. Its performance is superior to the traditional low molecular weight inorganic salts such as aluminum sulfate, ferrous sulfate and so on. Another dosing less, alum large, in addition to COD, color and suspended solids good performance and so on. The technology uses aluminum bauxite or aluminum plant by-product aluminum ash, industrial hydrochloric acid or waste hydrochloric acid as raw materials, one-step production of polyaluminum chloride, product quality in line with GB15892-2006 standards, to the advanced level of similar foreign products. Features: The technology is simple, the process is short, investment, equipment reliability, low cost, product quality and stability, the product can be made according to user needs liquid or solid products, product quality to the leading domestic level. Product quality indicators: liquid products: Al2O3 ~ 5.5% ~ 12%, the basic degree of 60 ~ 80%, water-insoluble l0.5%. Solid product: Al2O3 ~ 28%, base degree 60 ~ 80%, water insoluble l1.0%.
