Polyaluminum chloride water manufacturers in the process of analysis of the causes of water insoluble material? Polyaluminum chloride water manufacturers in the process of analysis of the causes of water insoluble material? Poly aluminum chloride production of raw materials in addition to aluminum, iron, but also contains 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. Customers have to consult the water insolubles encountered in the process of water purification, the traditional polyaluminum chloride compared with the new poly aluminum chloride, the general composition of the raw materials used in the complex, the more finely crushed, the higher the rate of dissolution of alumina , Will cause insoluble matter difficult precipitation. According to the manufacturer of filter polyaluminum chloride, at present, solid-liquid separation is generally implemented in the following three ways at home: natural sedimentation method usually takes a very long time and requires a certain site to build a large settling pond; High investment, high cost, and some horizontal spiral centrifuge, the cost of investment in a large industry; dosing polyacrylamide and other coagulant, control the amount invested, the effect is good. Polyaluminum chloride through the frame filter can be continuously separated and separated from the liquid solid insoluble particles, does not affect the use of the solution. With frame filter press can maintain degreasing liquid and the low concentration of particles in the phosphating solution to extend the life of the solution to extend the cleaning cycle of the spray system. Plate frame filter press is characterized by continuous cleaning solution, the output of non-aqueous waste, degreasing tank and the phosphate tank can not long down slot, reducing the waste of solution.
