  • Can polyacrylamides improve coagulant effectiveness?
  • The effectiveness of primary coagulants can be improved by using polyacrylamides (PAM) as coagulant aids. They can enhance the formation and sedimentation of flocs, which can aid in removing MPs.
  • Can polyacrylamide coagulation improve sludge dewatering performance?
  • Enhancing sludge dewatering can effectively reduce the operational costs of wastewater treatment plants. In the present study, a synergistic process combining polyacrylamide (PAM) coagulation with Fe 2+ /CaO 2 Fenton-like oxidation was proposed to improve the performance of sludge dewatering.
  • Does cationic polyacrylamide improve the removal efficiency of MPs during coagulation?
  • The removal efficiency of MPs (PE) (0.5 mm) was increased from 25% to 61% when cationic polyacrylamide (PAM) was added to AlCl 3 ·6H 2 O [ 20]. As a result, various experimental conditions must be used to improve the removal efficiency of MPs during coagulation processes.
  • How does coagulant dose affect MP removal and disinfection by-product distribution?
  • MP removal and disinfection by-product component distribution depend on the coagulant dose. The zeta potential of MPs decreases with a positive charge, so coagulant dosage increases coagulation efficiency. Humic substances on MPs can act as a bridge to the coagulant during coagulation, enabling more efficient removal.
