  • How cationic polyacrylamides are used in sludge dewatering?
  • Chemical conditioning by the cationic polyacrylamides (CPAMs) has been extensively used in the process of sludge dewatering owing to their advantages such as less dosage, higher efficiency, facile operation and affordable price , .
  • What is cationic polyacrylamide (CPAM)?
  • Cationic polyacrylamide (CPAM) is one of the most widely applied polymers due to its high performance in flocculation, sludge dewatering, and harvesting microalgae [ 6, 7, 8, 9, 10, 11, 12, 13 ].
  • How CPAM is used in sludge dewatering?
  • It is very significant and valuable to apply CPAM in the field of sludge dewatering and improve the sludge dewatering and conditioning effect. CPAM is mainly prepared by polymerization of AM and cationic monomer. Acryloxy trimethylammonium chloride (DAC) is one of the more commonly used cationic monomers.
  • How to improve flocculation efficiency of cationic polyacrylamide (CPAM)?
  • Among them, flocculation is an efficient and simple physicochemical method, and to be choose proper flocculant is the key factor to enhance flocculation efficiency (Li et al. 2017; Luo et al. 2013 ). Cationic polyacrylamide (CPAM) is a water-soluble linear polyelectrolyte with high molecular weight and positive charge density.
