Cationic polyacrylamide in industrial applications, sometimes because of the product with the wrong or the use of errors affect the effect of the product is destroyed, the effect of cationic PAM effect is not ideal elements are many, so the following for everyone The product under what circumstances will be affected.
Cationic polyacrylamide PAM is more suitable before the first-order treatment of the structure. When the content of the suspended matter is low, it is appropriate to apply the filter before the filter so that the amount of the particles does not occur in order to form the fine floc The actual reduction of the concentration and the deterioration of the surface properties of the coagulated suspension, the time interval between the addition of the coagulant and the flocculant to the water, usually between 1-4 minutes.
The lower the temperature and turbidity of the water, the higher the chroma of the water, the longer the time interval between the coagulant and the flocculant, taking into account the disinfection of the water. If PAM is added before the addition of chlorine, The degree of disinfection may be degraded, which may worsen the process properties of the cationic macromolecule flocculant because pre-chlorination may mask the cationic polyacrylamide polymer against the disinfecting process of the biological object and the polymer is destroyed by the oxidant.
Industrial use of cationic polyacrylamide PAM is a high-cost products, so the effect of the application effect is very important, so we should be based on a certain product attributes and the nature of the industry to choose and strict process technology
