Anionic polyacrylamide is a water-soluble polymer. Because of its molecular chain contains a certain number of polar groups, it can be adsorbed by the water suspended solid particles, so that the particles between the bridge or through the charge and the particles condensed to form a large floc. Therefore, it can accelerate the sedimentation of particles in the suspension, there is a very clear way to speed up the clarification of the solution to promote filtration and other effects. Mainly used for a variety of industrial wastewater flocculation settlement, sediment clarification, such as iron and steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater treatment, sludge dewatering and so on. Can also be used for clarification and purification of drinking water.
In the industrial wastewater treatment, especially for the suspended particles, coarse, high concentration, the particles with positive charge, water PH value of neutral or alkaline sewage such as steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater Sewage, cationic polyacrylamide treatment is very good.
In drinking water treatment. Many of our water plant water from the river less mud and mineral content is high, relatively turbid, although the precipitation treatment, but still fail to meet the requirements, need to add a flocculant in order to make water quality clear, many water plants using inorganic flocculation But the dosage is large, resulting in the effect of sludge increase is not good, the use of anionic polyacrylamide as a flocculant, dosage is inorganic flocculation of one of the 50, the effect is the inorganic flocculant several times to several Times, especially Lubang polyacrylamide, the residual monomer has reached the food grade (less than 0.05%), close to the advanced level of foreign, non-toxic, more appropriate for the treatment of drinking water, for the serious pollution of organic rivers and anionic polypropylene Amide with the use of better results.
Polyacrylamide is used as a starch plant and alcohol plant for the loss of starch and distillate recovery. Now a lot of starch plant discharged from the waste water is very high, after the impact of the environment, waste of resources, plus PAM, so that starch precipitation, sedimentation filter press filter into a cake can be used for feed, alcohol plant a lot of distiller's grains is With this process of processing, an alcohol factory in Heilongjiang is polyacrylamide as a flocculant, the recovery of distiller's grains and achieved great economic benefits.
Polyacrylamide used as oil field profile control water shutoff agent, three oil recovery agent. Polyacrylamide is used as a papermaking agent. PAM is widely used in papermaking. It can be used as a long fiber paper dispersant, wet and dry enhancer, retention agent, filter aid and flocculant for papermaking wastewater.
