Commonly used Poly aluminum chloride content of solid poly aluminum which? Commonly used poly aluminum chloride content of solid poly aluminum which? Polyaluminium chloride and the traditional inorganic coagulant fundamental difference is that the traditional inorganic coagulant is a low molecular weight crystalline salt, and the structure of polyaluminum chloride by the morphological diversity of polycarboxylate complex composition, flocculation and sedimentation speed, apply PH value of a wide range of non-corrosive pipeline equipment, water purification effect is obvious, can effectively remove the water color SS, COD, BOD and arsenic, mercury and other heavy metal ions, PAC products are widely used in drinking water, industrial water And sewage treatment field. Poly aluminum chloride is generally divided into these three categories: 1, drum-type poly (co) aluminum chloride content of 24-26%, high water-insoluble, mostly used for sewage treatment. 2, plate and frame poly (co) aluminum chloride aluminum content of 28-30%, low water insoluble, for sewage treatment and drinking treatment. 3, spray-dried poly (aluminum) aluminum chloride content of 28-30%, low water-insoluble, fast dissolution rate for drinking water and higher standards of water treatment. The use of PAC products, according to the different turbidity of raw water, determine the optimal dosage. Such as the content of PAC in 24% - 30%, 24% -26% This is more for paper, 28% of the PAC are used for a wide range of industrial, domestic sewage treatment , Metallurgy, paper making, circuit boards, leather, printing and dyeing, medicine, electroplating and other industries. 29% -32% of the content is used for water and drinking water industry-specific. Therefore, different content of PAC is not the same. Poly aluminum chloride prices according to the content of aluminum trihydrate in aluminum chloride can be divided into four: 24,26,28,30. These three have different prices, uses and scope of use, according to their own needs to make a reasonable choice. 1) content of 30%: (price 1300 yuan / ton) higher purity can be used for drinking water, in addition to fluoride, chlorine and other special water quality treatment. 2) content of 28%: (Price 1200 yuan / ton) can be widely used in life, production and domestic sewage, industrial wastewater purification. 3) content of 26%: (price 1000 yuan / ton) This kind of price is cheaper, but also can be used reasonably. Poly aluminum chloride PAC synthesis of raw materials, according to the sources of raw materials can be divided into three categories: industrial waste, including aluminum, aluminum slag, aluminum ash, aluminum foil waste, aluminum chloride wastewater; aluminum ore, including bauxite Mine, clay, kaolin, coke, coal gangue, alunite, etc .; chemical products and intermediates, including crystalline aluminum hydroxide, aluminum trichloride, sodium aluminate and so on. Poly aluminum chloride PAC synthesis method according to the different raw materials, can be divided into metal aluminum method, aluminum oxide method, activated aluminum hydroxide method, aluminum chloride method. Also in accordance with the different production processes are divided into acid, alkali, neutralization, pyrolysis, pressure reaction, gel method, electrodialysis, electrolysis and so on.
