  • 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.
  • Which cationic polymers are used to harvest freshwater microalgae?
  • Two positively charged cationic polymers including poly [2 (acryloyloxy)ethyl]trimethylammonium chloride (PAETAC) and poly (3 acrylamidopropyl)trimethylammonium chloride (PAmPTAC) were synthesized using the UV-induced radical polymerization, for harvesting both freshwater and marine microalgae.
  • How does CPAM affect wastewater turbidity?
  • Figure 7 shows that with increasing CPAM dosage and stirring time, the wastewater turbidity first decreased and then increased under the condition of fixed wastewater pH, and when the CPAM dosage and stirring time were in the range of 5.5 to 6 mg·L −1 and 5 to 7 min, respectively, the wastewater turbidity had a minimum value.
