  • 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.
  • Who bought polyacrylamide flocculant?
  • Commercial flocculant of polyacrylamide (PAM, MW of 2000–14,000 kDa) was bought from Aladdin Industrial Corporation (Shanghai, China). Anhydrous ethanol and acetone were supplied by Zhenqi Chemical Reagent Co., Ltd (Shanghai, China).
