Liquid polyaluminum black sticky cause of this situation affect the efficacy? Liquid polyaluminum black sticky cause of this situation affect the efficacy? Domestic production of polyaluminum chloride is divided into two kinds of solid and liquid, but the liquid is usually transparent yellowish, sometimes because of the impurities into a gray-black mucus, so how to deal with such mucus? Filter water purification technology for everyone to solve such problems. In fact, sometimes due to impurities caused by mucus grayish black, this is because the chemical reaction took place. Will not affect the water treatment effect. Filter water purification production and marketing of paper-based high-grade poly aluminum and many other advantages in one of the high-performance composite products. All water treatment products to the latest national standard for the test. At present for the product, the filter source of purified water treatment agent to detect the content as a standard. High-purity pure aluminum chloride water treatment is the current water treatment industry, the best polymer water treatment agent, the effect of various concentrations of water treatment is quite good, and with less, the amount of sulfuric acid than the same concentration of 50% less than the same The concentration of polyaluminum chloride less 10%. High effect and low energy are mainly high degree of polymerization of PAFC because iron salt and aluminum salt water treatment agent can only generate AL (OH) 2 +, AL (OH) + 2, Fe (OH) 2+, Fe ( OH) +2 and other simple hydrolysis of hydroxyl ions, and PAEC itself is AL3 +, Fe3 + pre-water products, which in addition to the hydrolysis of hydroxyl ions, it can generate a large number of ionization degree, positive charge: AL4 ( OH) 4 +8, Fe4 (OH) 4 +8 ...... And so on to neutralize the colloidal particles in the water charge and compression of the electric double layer, at the same time hydroxyl bridging, crosslinking, surface adsorption and other series of reactions, Collision, condensed into a large alum, rapid precipitation.
