  • 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.
  • Is polyacrylamide a good flocculant?
  • Polyacrylamide (PAM, − CH 2 CHCONH 2−) is a flocculant that is commonly used in the treatment of drinking water. By building bridges between destabilised particles, PAM could create micron-sized aggregates with good settling qualities. Cationic, nonionic and anionic PAM materials have been investigated for their flocculation capabilities.
  • What is polyacrylamide (PAM) used for?
  • npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
  • 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 .
