Anionic water is mainly used for living and production, industrial and urban sewage treatment. Also apply during the preparation of alumina flocculation of red mud and mud-liquid separation. Cationic high molecular weight, mainly for the water suspension and flocculation of suspended matter cloud precipitation, the acid and acidic solution containing an organic flocculation of suspended matter is very difficult. In this case, cationic polyacrylamide can be effective for flocculation and sedimentation, indicating outstanding performance. 0.1-0.2% in water use form, must be formulated PH≤7 of water, dubbed highly dilute solution hydrolysis. Should vary with the day spent with the use or not suitable for prolonged storage. Polyacrylamide (PAM) points: anionic, cationic polyacrylamide polymer, to improve the treatment process sedimentation, clarification, filtration, centrifugation process efficiency. CPAM acidic or alkaline medium showed a cationic polyacrylamide of high quality, it is usually more than the anionic or nonionic low molecular weight polyacrylamide polyacrylamide use, its performance Cheng Jie sewage mainly by charge neutralization and the effect is obtained. The main function of this type of flocculant flocculation with anionic polyacrylamide negative charges, with turbidity, bleaching function. Alcohol and other waste in the factory, monosodium glutamate factory, sugar factory, meat plants, beverage plants, printing and dyeing process using cationic polyacrylamide than to anionic polyacrylamide, nonionic polyacrylamide or inorganic high effect several times or several times, because this type of waste water generally has a negative charge. CPAM apply high-speed centrifuges, belt filter press, plate and frame filter press sludge dewatering and other special machinery, with the formation of floc fast oilfield chemical additives PAM, floc thick nonionic PAM PAM export, resistance to compression and shear, a group of good polyacrylamide, easy to peel and cloth and so on. So dewatering rate, the filter cake was low, with less, can greatly reduce the user cost. It can also be used hydrochloric acid, sulfuric acid concentration in the liquid, separating purification contained therein suspended material. Therefore, the product is widely used in urban sewage treatment plants, breweries, food factories, tanneries, paper mills, petrochemical, metallurgy, chemical industry and other sludge dewatering.
