Lead to polyaluminum after the addition of part of the precipitate can not precipitate after the treatment solution led to polyaluminum chloride after the suspension part of the precipitation did not settle the treatment of the first use of PAC users often ask this question, For the 100ml flocculation test, when the concentration of PAC and raw water is 10mg / L, the effect is better, flocculation and sedimentation are faster, but in the end there are always many small suspended solids precipitation for a long time, we actually use the honeycomb Slope sedimentation tank there is such a problem, there are always many small suspended sediments down to the back process, what good measures to solve it? Now filter water polyaluminium chloride manufacturers to answer your questions: depends on what system you use, if you are casting two cold water, then you have to test the device, the average user in this experiment can try to use the polymer chlorine Ferroalloy, used in the clarification of the river, add less flocculation situation is not good, and other flocs to precipitation, large particles quickly, the small is always suspended in water, or with the use of polyacrylamide, the choice of Good polyacrylamide, should be avoided, the other current mass of aluminum chloride vary greatly, you can filter more than a few, different processes will have some production, from your point of view, I suggest you use bauxite production The use of PAC. Polyaluminum chloride used in the process of settling no less than, you can use with polyacrylamide, the focus is on the quality of polyaluminum chloride you use, a little better, there is almost no water-insoluble PAC, the purchase of polymeric chlorine Aluminum selection is very important to the manufacturers. Filter water source is a national large-scale manufacturer of PAC, full of qualifications to ensure that the production of PAC content, the indicators are in line with the national standard PAC, many domestic and foreign sewage treatment selected filter .
