Filter Summary Polyaluminum Chloride three solid-liquid separation of technical methods Filter Summary Polyaluminum chloride three solid-liquid separation methods Polyaluminum chloride through the frame filter can be continuously filtered liquid separation of solid insoluble Particles, does not affect the use of the solution. Polyphenylalanine household frame filter press can maintain degreasing liquid and low concentrations of particles in the phosphating solution to extend the life of the solution and extend the cleaning cycle of the sprinkler system.The frame filter features continuous cleaning solution, Output of non-aqueous waste, degreasing tank and phosphate tank can not long-term trough, reducing the waste solution. This shows that polyaluminum chloride to overcome the problem of water insoluble material has a certain effect. Polyaluminum raw materials, in addition to aluminum, iron, but also contain other metals, such as calcium. Magnesium and so on. The appearance of these so-called "impurity" metal ions is caused by impure raw materials. Experiments show that, like calcium, magnesium and other metal ions, often can improve the flocculation effect of the main coagulant, for some industrial wastewater, the effect is more significant. Because some effective metal ions can carry raw water itself insoluble precipitate, to promote the product flocculation sedimentation purposes. Filter polyaluminum chloride manufacturers summarized the following three ways to achieve solid-liquid separation: 1, natural sedimentation method, usually takes very long time, the need for a certain site to build a large sink; 2, frame filter press filter, but High investment, high cost, and some horizontal spiral centrifuge, the cost of investment industry is large; 3, adding polyacrylamide and other coagulant, control the amount put, the effect is good.
