Polyaluminium chloride can be treated directly sewage it? Customer consultation Poly aluminum chloride manufacturers of technical staff: "They think that the use of PAC prior to dissolve too much trouble, water purification agent can not be treated directly sewage?" The answer to this question, the source of filtered water is , Polyaluminum chloride can be used directly, but it will certainly cause economic losses to you! Polyaluminum chloride water purification agent directly added to the sewage, the suspension will quickly wrapped flocculation sedimentation, resulting in equipment clogging, and the amount of water purifying agent is the amount of aqueous aluminum chloride solution 2-3 times, though easy, but A direct result of increased use costs. Polyaluminum chloride is an inorganic polymer water purifying agent, which is produced by the bridging effect of hydroxyl ions and the polymerization of polyvalent anions, and has a higher molecular weight and a higher charge of an inorganic polymer water-treating agent. Polyaluminum chloride flocculation sedimentation speed, suitable for a wide range of PH value, 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. The correct use of PAC: 1, the use of water purification agent should be based on the water quality of a small test, select the water effect is good, the best volume of small points. The solution should be used along with the use of non-potable water should be based on the actual situation of the selected amount. 2, the use of solid, the first water to dissolve to 10-25% to accompany the solution, and then dilute the water to the desired concentration, dissolved in the first water slowly feeding, and continue to stir. 3, different manufacturers or different grades of water treatment agents can not be mixed, and may not be mixed with other chemicals. 4, stock solution and dilute slightly corrosive, but lower than other kinds of inorganic flocculant. 5, the effective storage period of the product: liquid for six months, solid two years. Solid product tide can still be used. 6, water purification agent polyaluminum chloride rationally added, purified water quality in line with drinking water health standards
