Applications of Polyacrylamide

　　Polyacrylamide is a widely recognised water purification agent. As a type of flocculant, it is categorised into cationic polyacrylamide, anionic polyacrylamide, and non-ionic polyacrylamide based on its manufacturing process. Polyacrylamide constitutes a linear polymeric compound. Its excellent water solubility enables polyacrylamide, as a water-soluble polymer compound, to be widely employed in numerous aspects of turbid water treatment.

　　Polyacrylamide is an organic polymeric flocculant and one of the most widely applied water purification agents in both industrial production and domestic use. It significantly enhances the flocculation of impurities in water, overcoming the tendency for flocs to float in low-volume water conditions. During water purification, it reduces alum consumption, lowers costs, improves wastewater treatment quality, removes colouration, renders water transparent, and eliminates organic matter and algae. When treating potable water with polyacrylamide, strict control of dosage is essential. Prior to use, the polyacrylamide type must be confirmed to ensure it is an anionic variety. Verify whether it is an anionic polyacrylamide, as only this type is suitable for potable water treatment. When treating drinking water, the polyacrylamide dosage must be significantly reduced. Only under strictly controlled usage can the treated drinking water be deemed completely safe, meeting the standards required for human consumption.
 

　　Following extensive experimentation by VICTOR Corporation, drinking water treated with VICTOR-produced polyacrylamide complies with the drinking water standards of most nations. Anionic polyacrylamide is not only suitable for drinking water treatment but also finds application in numerous sectors including the iron and steel industry, metallurgical industry, electroplating plants, coal washing, and sewage sludge dewatering. Cationic polyacrylamide also boasts extensive applicability. Initially employed in the petroleum sector, its superior water solubility—enabling complete dissolution and flocculation even in cold water—alongside remarkably efficient dosing yields exceptional results. When combined with inorganic flocculants, it significantly reduces flocculation time.

　　Consequently, it finds application in municipal sewage treatment, papermaking, food processing, metallurgy, mineral processing, dyeing, industrial wastewater treatment, electroplating plants, coal washing, sludge dewatering, and numerous other sectors. Non-ionic polyacrylamide also boasts extensive applicability. It is primarily employed in treating industrial effluents and waste liquids, municipal sewage treatment, and particularly excels in managing acidic wastewater. Among all water purification products, it demonstrates exceptional efficacy in treating acidic turbid water. Non-ionic polyacrylamide is further suitable for highly polluting industries such as papermaking and textile dyeing.
