Polyaluminum chloride solubility is good? In the process of dissolving the polyaluminum chloride into liquid, some customers may encounter solid product can not be completely dissolved, appear on the surface is the bottom of clear water tank polyaluminium chloride precipitate too much, in fact, to avoid this situation is very simple. When we use a barrel mixer, you need to stop mixing clockwise, the time to control within 10 minutes, of course, we must also consider the local temperature, stirring speed should be uniform, to avoid dilution of the liquid when completely dissolved problems. Sewage types more, rule up more headache, because according to the sewage of each industry to prescribe the right medicine, it is relatively difficult to deal with large, polyaluminum chloride as the parent, mixed with other agents, formulated into complex PAC, sewage treatment can be obtained Surprise effect. Polyaluminum chloride used in mineral raw materials in general complex ingredients, the more finely crushed, the higher the rate of dissolution of alumina, but also caused insoluble precipitation difficult. At present, domestic manufacturers of PAC generally use the following three ways to achieve solid-liquid separation: 1, the natural sedimentation method, usually takes a very long time, the need for a certain site to build a large sink; 2, frame filter press filter, However, high investment, high cost, and some use of horizontal spiral centrifuge, the cost of investment industry is large; 3, adding coagulant polyacrylamide and other control, put a good amount, the effect is good. Poly aluminum chloride can be widely used in drinking water, industrial water and sewage purification. Fast response, less consumption of drugs. Alum large, fast settling, good filtration, can improve equipment utilization, low cost of making water. Overdosing does not produce side effects, easy operation and management; no corrosion of water equipment and piping.
