- How can polyacrylamide and inorganic flocculants improve water quality?
- Improve water quality. In drinking water treatment and industrial wastewater treatment, the combined use of polyacrylamide and inorganic flocculants can significantly improve water quality. Improve the strength and settling speed of flocs.
- Can polyacrylamide be used as a coagulant aid?
- Reduce the amount of flocculant. Under the premise of achieving the same water quality, the use of polyacrylamide as a coagulant aid in combination with other flocculants can greatly reduce the amount of flocculant used. Improve water quality.
- What are the different types of polyacrylamide water treatment?
- Description: According to ionic characteristics, it can be divided into four types, non-ionic polyacrylamide NPAM, anionic polyacrylamide APAM, cationic polyacrylamide CPAM and amphoteric polyacrylamide. At present, the PAM water treatment is generally anionic type.
- What are the benefits of polyacrylamide flocs?
- Improve the strength and settling speed of flocs. The flocs formed by polyacrylamide have high strength and good settling performance, thereby increasing the speed of solid-liquid separation and benefiting sludge dewatering. Anti-corrosion and anti-scaling of circulating cooling system.
