Polyacrylamide (PAM), commonly known as flocculant or coagulant, belongs to the coagulant.The average molecular weight of PAM ranges from thousands to tens of millions of molecules, and there are a number of functional groups along the bonded molecules, most of which can be ionized in the water, which belongs to the polymer electrolyte. According to the characteristics of its dissociable groups are divided into anionic polyacrylamide, cationic polyacrylamide, and nonionic polyacrylamide.
Function
PAM is a high quality flocculant, and the organic polymer flocculant has a huge surface adsorption effect by forming a larger floc between the particles.
Characteristics
PAM is used for flocculation, with the flocculated species surface properties, especially the kinetic potential, viscosity, turbidity and pH value of the suspension is related to the kinetic potential of the particle surface, is the cause of particle blocking adding the surface charge opposite PAM, can make the kinetic potential decrease and cohesion. Polyacrylamide (PAM) is a water-soluble polymer, insoluble in most organic solvents, has good flocculation, can reduce the friction resistance between liquids. The concentration of suspended solids in the wastewater is not high, and it does not have the performance of condensation. In the precipitation process, the solid particles do not change their shape, nor do they bond with each other, and each completes the precipitation process independently.
Application
PAM is mainly used for sludge dewatering, solid-liquid separation and recovery of coal washing, mineral processing and paper wastewater. It can be used in the treatment of industrial wastewater and urban domestic sewage. In the paper industry, PAM can improve the dry and wet strength of paper, improve the retention rate of fine fibers and fillers.PAM can also be used as an additive for mud materials used in oil field and geological exploration drilling.
Conclusion
As an important water treatment agent, PAM plays an important role in the field of water purification and sewage treatment. It can quickly and effectively remove suspended matter, colloids and organic matter in water, improve treatment efficiency and water purification effect. PAM has a wide range of applications. By using PAM for water treatment, we can improve the water quality environment, protect and improve the utilization efficiency of water resources, and create more favorable conditions for human life and development
