- What is cationic polyacrylamide?
- Our cationic polyacrylamide is available in solid powder and emulsion forms. The polyacrylamide is a synthetic cationic polymerization flocculants and polymer flocculant powder. It is mainly related to chain length and the charge of the dewatering performance of polyacrylamide excessive dosage.
- What is cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is one of the most frequently used flocculants with high intrinsic viscosity and charge density. This flocculant is a water-soluble acrylamide-based polymer having cationic quaternary ammonium groups .
- What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.
- Which cationic polymer has the best flocculation efficiency?
- The PAmPTAC polymer had an optimal dose at 252 mg/g dry biomass. The difference in flocculation efficiency between two polymers is likely due to the differences in molecular weight. In the flocculation process by cationic polymers, charge neutralization of microalgal cells initiates floc formation.
