Poly aluminum sulfate is a composite polymer with large molecular structure, strong adsorption capacity and better water purification effect than all traditional inorganic water purifying agents. When the raw water is input, the floc is large, the precipitation speed is fast, the activity is high, and the filtration is good. And the adaptability of various raw water is strong, the pH value of water is very small (pH value 4-11). No matter the turbidity of raw water or the concentration of wastewater pollutants, the purification effect is remarkable. Less dosage: less corrosive to equipment and pipe, easy to operate, small dosage and low purification cost.
1. Polyaluminium sulfate is used in water purification and as a medium in textile printing and dyeing. In water purification, polymeric aluminum sulfate causes impurities to condense and easier to precipitate and filter.
2, when dissolved in a large number of neutral or slightly alkaline water, resulting in colloidal precipitation of aluminum hydroxide, Al (OH) 3. When printing and dyeing cloth, the aluminum hydroxide colloid makes the dye more easily stick to the plant fiber.
3, polyaluminium sulfate is also used to regulate the pH value of the soil, because the polymerization of aluminum sulfate hydrolysis to produce aluminum hydroxide, while producing a small amount of dilute sulfuric acid solution.
