The role of anionic Polyacrylamide in sewage treatment:
Anionic Polyacrylamide is a water-soluble polymer,suitable for higher concentration and positively charged inorganic suspended matter,as well as coarser suspended particles (0.01-1mm) pH value of neutral or alkaline solution.It is mainly used for flocculation and settlement of various industrial wastewater,clarification treatment (such as iron and steel plant wastewater,electroplating plant wastewater,metallurgical wastewater,coal washing wastewater, etc.) sewage treatment and sludge dewatering, etc.,and can also be used for drinking water clarification and purification treatment. As its molecular chain contains a certain number of polar groups,it can adsorb the suspended solid particles in the water,so that the bridge between the particles or through the charge neutralisation to make the particles coalesce to form large flocs,so it can accelerate the settlement of the particles in the suspension,and…
