For those familiar with the water treatment industry, both non-ionic polyacrylamide and
anionic polyacrylamide are likely well-known. Some customers may then ask: under what circumstances should non-ionic be used for wastewater treatment? When should anionic be used? With this question in mind, we shall now detail the distinctions between non-ionic and anionic polyacrylamide. We hope this proves helpful!
Non-ionic polyacrylamide accelerates the settling of suspended particles within wastewater. It achieves rapid clarification and filtration effects within a very short timeframe.
Anionic polyacrylamide is a high-molecular-weight polymer. It is currently primarily employed in industrial wastewater treatment, such as steel mill effluent, mineral processing plant effluent, metallurgical wastewater, and coal washing plant effluent treatment. Additionally, it can be used in drinking water treatment and for clarification purposes.
Similarities between non-ionic and anionic polyacrylamide:Both water treatment agents belong to the polyacrylamide family. Non-ionic and anionic polyacrylamide (PAM) are linear macromolecular polymers distinguished by molecular weight. Both are suitable for wastewater treatment, with particularly prominent applications in thickening agents and adhesives industries.
During external application, both must first be dissolved into a solution before being added to wastewater to achieve purification.
Differences between non-ionic and anionic polyacrylamide:
- Molecular weight: Non-ionic polyacrylamide ranges from 400 to 1200 molecular weight units. Anionic polyacrylamide ranges from 400 to 2500 molecular weight units.
- Differences in wastewater treatment applications:
- Non-ionic PAM is primarily used for treating slightly acidic wastewater. Anionic polyacrylamide is mainly employed for treating inorganic wastewater and neutral wastewater.
- Non-ionic polyacrylamide exhibits a lower degree of hydrolysis. Anionic polyacrylamide possesses a moderate degree of hydrolysis. The application scope of anionic PAN is considerably broader than that of non-ionic polyacrylamide.
- Price: Non-ionic polyacrylamide is priced slightly higher than anionic polyacrylamide.
