Cationic polyacrylamide is commonly used as flocculant and precipitator in industrial sludge wastewater treatment. Because different industries treat water quality in different ways, the problems encountered in the process of treatment are also different, and various problems may affect its use.
Manufacturers of cationic polyacrylamide claim that PAM is a polymer. It is currently used for sludge sewage treatment. In order to improve the use of products, water purification materials remind you to pay attention to the following problems: floc size. The selection of PAM floc size will directly affect the effluent velocity. If it is too large, the floc will produce more water and the mud cake will be reduced.
Select the appropriate sludge. Sludge is mainly divided into organic pollutants and inorganic pollutants, mainly used for organic sludge treatment. The corresponding polypropylene flocculant was added to the inorganic sludge. When the base is very strong, cationic polyacrylamide is not suitable for acids.
Polyacrylamide (PAM) is a linear polymer, chemical formula is (C3H5NO) N. It is a hard glassy solid at room temperature. The products are liquid glue, latex and white powder particles, translucent beads and flakes. Good thermal stability. Can be dissolved in water in any proportion, aqueous solution is uniform transparent liquid. After long-term storage, the solution viscosity will decrease due to slow degradation of polymer, especially when the storage conditions are poor.  Polyacrylamide, as lubricant, suspension agent, clay stabilizer, oil displacement agent, water loss reducer and thickener, has been widely used in drilling, acidification, fracturing, water plugging, cementing and secondary oil recovery, tertiary oil recovery. It is a very important oil field chemical.Learn more
Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. It is a light yellow amorphous powdery solid and easily soluble in water. 10% (mass) aqueous solution is red-brown transparent solution and hygroscopic. Polyferric sulfate is widely used in drinking water, industrial water, all kinds of industrial waste water, municipal sewage, sludge dewatering purification treatment.Learn more
