Can cationic flocculants be used 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. Cationic polyacrylamide (CPAM) were used extensively in water treatment, enhanced oil recovery and sludge dewatering.

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.

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 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).

Does the copolymer conditioned sludge improve the dewatering performance?

This result shows that after the sludge was conditioned by the copolymer, the bound water in the floc gaps was converted into free water, thereby improving the dewatering performance.
