  • Can cationic polyacrylamide be used in water treatment and sludge dewatering?
  • To read the full-text of this research, you can request a copy directly from the authors. Cationic polyacrylamide (CPAM) were used extensively in water treatment, enhanced oil recovery and sludge dewatering. The review summarized the synthesis methods research progress of cationic flocculants.
  • Are cationic copolymers used in sludge dewatering?
  • Four groups of synthesis technologies of cationic copolymers were reviewed, including aqueous solution polymerization, dispersion polymerization, inverse emulsion polymerization and photo initiated polymerization. Furthermore, the paper reviewed that the application of cationic flocculants in sludge dewatering treatment.
  • Are cationic polyacrylamide copolymers bad for the environment?
  • Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils.
  • Can cationic flocculants be used in sludge dewatering treatment?
  • Furthermore, the paper reviewed that the application of cationic flocculants in sludge dewatering treatment. Based on these reviews, the future research perspectives of synthesis and application on cationic flocculants in sludge dewatering treatment were proposed.
