  • 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.
  • Does polyacrylamide flocculating sludge emit a strong odor?
  • Volume 234, article number 630, ( 2025 ) The supernatant fluid and sludge produced by traditional polyacrylamide flocculant (PAM) flocculation of municipal sewage emit a strong odor, and the dewatering performance of flocculant flocculating sludge based on acrylamide as the main synthetic raw material remains undesirable.
  • Can biopolymer based flocculants be used for sludge dewatering?
  • Recently, the application of biopolymer-based flocculants in the flocculation for sludge dewatering is a hot research direction. Compared with traditional inorganic coagulants and synthetic organic flocculants, biopolymer-based flocculants have a higher sludge dewatering efficiency and wider pH adaptability.
  • Does cationic polyacrylamide flocculate Phaeodactylum tricornutum?
  • However, Nguyen et al., observed high flocculation efficiency of marine microalgae Phaeodactylum tricornutum with a cationic polyacrylamide flocculant (FO3801). The discrepancy in the literature suggested that a future flocculation study using one type of polymer with multiple marine species.
