Polyacrylamide is widely used in the paper making industry. It can be used as paper making dispersant, paper making retention aid, and paper making wastewater treatment flocculant.
- Polyacrylamide as paper making dispersant: Generally, we use anionic polyacrylamide with molecular weight between 14-18 million.
- Polyacrylamide as paper making retention aid: It is recommended to use high quality cations, so that the effect of filtration aiding is better, and the dosage is more economical.
- Polyacrylamide as paper making wastewater treatment flocculant: In the process of paper making wastewater treatment, the selection of polyacrylamide should be based on the situation of sewage, on-site sewage treatment process and sludge dewatering equipment. Generally, cationic polyacylamide with molecular weight of more than 9 million is selected as sludge dewatering agent.
