  • 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 CPAM product was selected as a flocculant?
  • The CPAM product No. CPAM-8.14-40.2 in Table 1 was selected as the flocculant, the wastewater identical to that of the single-factor test was the treated object, reducing the wastewater turbidity was the optimization goal, and the CPAM dosage, the wastewater pH and the stirring time were influencing factors.
  • How does CPAM affect flocculation?
  • The CPAM dosage, wastewater pH and stirring time significantly impacted the flocculation effect, and inflection points were observed. A model that could guide CPAM-8.14-40.2 flocculation was obtained by RSM tests.
  • 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 .
