  • 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.
  • Why is flocculation important for sludge dewatering?
  • Flocculation is an important pretreatment technology for sludge dewatering, and the flocculant’s performance is the key factor to determine the flocculation effect.
  • What is cationic polyacrylamide (CPAM)?
  • Cationic polyacrylamide (CPAM) is a water-soluble linear polyelectrolyte with high molecular weight and positive charge density. Because of its low cost, high efficiency, and simple operation, CPAM is widely used as a chemical conditioner for flocculation pretreatment of sludge before mechanical dewatering (Sun et al. 2018; Zhou et al. 2014 ).
  • Is sewage suitable for flocculation treatment with CPAM?
  • Most sewage containing suspended solids exhibits a colloidal property and negative charge and is very suitable for flocculation treatment with CPAM. UV-initiated polymerization is a new method for preparing organic flocculants, and there have been many studies in this field .
