What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.
Which cationic polymer has the best flocculation efficiency?
The PAmPTAC polymer had an optimal dose at 252 mg/g dry biomass. The difference in flocculation efficiency between two polymers is likely due to the differences in molecular weight. In the flocculation process by cationic polymers, charge neutralization of microalgal cells initiates floc formation.
Does polyacrylamide structure affect flocculation of bentonite clay?
Shaikh and coworkers studied the effect of polyacrylamide structure on the flocculation of bentonite clay. 208 Using turbidity as a powerful measure, they compared flocculations using cationic, anionic, and amphoteric polyacrylamides of varying molecular weights.
Can cationic polymer flocculants be developed by photo-polymerization?
In this study, we utilized recent developments in the photo-polymerization technique to develop two cationic polymer flocculants by polymerizing two types of monomers for harvesting Chlorella vulgaris ( C. vulgaris) and Porphyridium purpureum ( P. purpureum ), which are freshwater and marine microalgae species, respectively.
