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.

What is cationic polyacrylamide (CPAM)?

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.

Can sewage flocculants use cationic polyacrylamide as a sludge dewatering agent?

The use of sewage flocculants will use of cationic polyacrylamide as a sludge dewatering agent.

What is a polymer sludge dewatering technique?

In brief, polymers exist as organic or inorganic materials which are either cationic, non-ionic, amphoteric or anionic charged materials (Lee et al., 2014). Their major purpose is to enhancing effluent flocculation which influences dewaterability ideally for WWTPs that use belt pressing as their sludge dewatering technique (Jiang and Zhu, 2014).
