  • 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 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.
  • How do cationic polymers cause flocculation?
  • In the flocculation process by cationic polymers, charge neutralization of microalgal cells initiates floc formation. High molecular weight polymer (i.e. very long chain of monomers) bridges destabilised microalgae flocs , , .
  • Can cationic polymer flocculants be developed by photo-polymerization?
  • In this study, we utilized recent developments in the photo-polymerization technique to develop two cationic polymer flocculants by polymerizing two types of monomers for harvesting Chlorella vulgaris ( C. vulgaris) and Porphyridium purpureum ( P. purpureum ), which are freshwater and marine microalgae species, respectively.
