1, used as a water treatment aid coagulant, anionic or cationic polyacrylamide usually with inorganic flocculant polyaluminum chloride and other products are used as water purification aid coagulant, can accelerate flocculation, rapid precipitation, to achieve the effect of sewage purification and impurity removal. Generally used in sedimentation tank, air flotation tank, Fenton process.
2, sludge dehydrating agent, cationic polyacrylamide can be used as sludge dehydrating agent, the main role is to remove the water in the sludge, reduce the water content of the sludge, and then through the belt filter press, plate and frame filter press, centrifugal filter press, pile screw machine and other sludge pressing equipment for sludge dehydration. Like construction mud and sand washing industry, anion is also used to dehydrate sludge, and anionic polyacrylamide is also selected for some river silting projects.
3, agricultural soil loosening agent, humectant. Irrigation can prevent soil compaction, improve the soil, and prevent soil erosion.
4, adhesive, because the polyacrylamide solution has a certain viscosity, it can be used as an adhesive in some industries. Absorbent material in baby diapers and so on.
