polymer based flocculants review of water purification
polyacrylamide (pam) is the basis for most commercial polymeric flocculants mentioned in the literature (anionic, cationic, or non-ionic); this polymer is also modifiable with combinations of comonomers. anionic pam; the most important category of pam, can be made by copolymerizing acrylamide with acrylic aid or partially hydrolysing

synthesis, properties and performance of organic polymers
polymeric flocculants are typically classified based on their ionic character: non-ionic, cationic, anionic and amphoteric. 2 commercial flocculants are often based on polyacrylamide (pam) and its derivatives since acrylamide is one of the most reactive monomers to undergo radical polymerization, thus allowing ultra-high molecular weight

- How is an anionic polyacrylamide flocculant synthesized?
- In this study, an anionic polyacrylamide flocculant was synthesized by ultrasonic initiated template copolymerization (USTP), using sodium allylsulfonate (SAS) and acrylamide (AM) as monomers, poly diallyl dimethyl ammonium chloride (polyDADMAC) as template, and 2,2′-azobis [2- (2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as initiator.
- 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.
- 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.
