Polyacrylamide factors: first, the floc size. Polyacrylamide floc size directly affects the speed of discharge water, much more will make the floc bound water decreased so that the mud biscuits. Second, the strength of the floc. Floc under shear stability without the need to adhere broken. When using polyacrylamide select the appropriate help to improve the stability of the molecular structure of floc. Third, the sludge characteristics. Sludge is mainly divided into two kinds of organic and inorganic, cationic polyacrylamide is mainly used for organic sludge, anionic polyacrylamide for inorganic sludge. Polyacrylamide type the correct choice can improve the results. Fourth, the product form. Polyacrylamide products are mainly dry powdered or granular, dissolved into a solution of polyacrylamide products can play better flocculation products. Fifth, the ion degrees. Different types of ion polyacrylamide for different processing, sampling inspection before use can better achieve flocculation. Polyacrylamide in various industries tips: First, the drinking water. Because the application of polyacrylamide in the field of more stringent drinking water, usually selected cationic polyacrylamide, and purity of the product is higher than the standard industrial use of the product. Second, aspects of urban sewage. Because the water effluent is more complex, and therefore more complex when the selection polyacrylamide. Bringing together different sectors of sewage, to deal with a big problem. Thus, in terms of urban sewage treatment, try to choose an efficient polyacrylamide products, which can effectively guarantee the treatment effect. Finally, industrial waste. For this field, on polyacrylamide relatively easy choice. Enterprises according to the degree of contamination of water quality to determine which content polyacrylamide use. Under normal circumstances are using anionic polyacrylamide, molecular weight by between 8 to 20 million, with the degree of contamination of sewage to select molecular weight polyacrylamide. In summary, the polyacrylamide different selection methods in different application areas, in general, is to consider the weight and water quality characteristics of polyacrylamide, polyacrylamide choose the best work by sampling and testing, so you can improve the use of the effect of polyacrylamide.
