- What is cationic polyacrylamide (CPAM)?
- At present, cationic polyacrylamide (CPAM) are the most widely used conditioners in most wastewater treatment plants, owing to its strong bridging function.
- 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.
