Enhanced municipal sludge dewaterability using an amphiphilic

Flocculation is an important pretreatment technique for sludge dewatering, the performance of employed flocculants is the key factor determine the flocculation efficiency. Herein, an amphiphilic cationic polyacrylamide (CPAM) with microblock structure was synthesized through template copolymerization initiated by ultrasonic.

effects of cationic polyacrylamide characteristics on sewage

Effects of Cationic Polyacrylamide Characteristics on Sewage

Cationic polyacrylamide (CPAM) is a type of polyelectrolyte that has been widely used as a sludge conditioner because of its low dosage requirement, high efficiency, and pollution-free effects. Previous studies report that CPAM dosage is critical in sludge conditioning because overdoses increase cost and deteriorate sludge dewaterability [12] .

The effects of the molecular weight (MW) and charge density (CD) of cationic polyacrylamide (CPAM) on sludge dewatering and moisture evaporation were investigated in this study. Results indicated that in sludge conditioning, the optimum dosages were 10, 6, 6, 4, and 4 mg g−1 CPAM with 5 million MW and 20% CD, 5 million MW and 40% CD, 3 million MW and 40% CD, 8 million MW and 40% CD, and 5

4. Sludge Dewatering Tests 4.1. Effect of Dosage on Sludge Dewatering Performance. The effect of dosage on the sludge dewatering performance is shown in Figure 3. The residual turbidity decreased with the increase of the flocculant dosage, which reached a minimum at flocculant dosage of 80 mg·L −1.

Cationic flocculants represent the large majority of the chemicals used in sludge dewatering. 2.2.1. Flocculation mechanism: Flocculation of sludge is the step in the process where destabilized particles are agglo-merated in aggregates called flocs. Flocculants, with their very high molecular weights (long chains of monomers) and their
