polymers for coagulation and flocculation in water treatment
the classification of the synthetic organic polymers used in water and wastewater treatment operations is based on the ionic charge present, e.g. cationic, anionic and non-ionic polyelectrolytes. cationic polyelectrolytes formed the largest number of polymeric coagulants that have been used in cf operations.
carbon and nitrogen stable isotope ratios can estimate,polyacrylamide degradation rates in the field when anionic pam degradation rates were based on δ 13 c, we found that pam degraded at a rate of 9.8% yr − 1 . we incorporated 897 kg pam ai ha − 1 into the soil in the spring every year for 3 yr to plots receiving 2691 kg ai pam applied ha − 1 from 1998–2000.
applications of cationic polymers in water treatment
the global market for coagulants and occulants used in water treatment in 2004 was estimated at $2.75 billion dollars annually, with a growth rate of ∼5.5% per year [1]. this includes inorganic and polymeric organic coagulants and occulants. synthetic cationic polymers (polyelectrolytes) and, to a much lesser degree, naturally occurring

- How is polyacrylamide biodegradable?
- Both single microbial species as well as mixed populations have been investigated for degradation. Biodegradation of polyacrylamide begins with amidase catalysed deamination of polyacrylamide to ammonia and polyacrylate. The liberated ammonia is then used as a nitrogen source for growth by the microbes.
- How does polyacrylamide biodegradation affect the fate of related polyacrylic acid?
- Polyacrylamide copolymers, either anionic or cationic, are potentially quickly converted to corresponding polyacrylate salts by deamination or hydrolysis. Therefore, biodegradation of related polyacrylic acid (or related salts) provides insights in polyacrylamide biodegradation and their fate.
- Is polyacrylate more recalcitrant to biodegradation than amide?
- The carbon backbone, polyacrylate, is more recalcitrant to biodegradation than the amide moieties. There are nevertheless reports on microbial growth with polyacrylamide and polyacrylate as the carbon sources.
- Are polyacrylates recalcitrant to degradation?
- Remaining polyacrylates are more recalcitrant to degradation. Polyacrylamide degradation has mainly been reported for aerobic bacteria. With fungi the degradation is initiated by secreted lignin degrading oxidases. Polyacrylamide may be degraded to acrylamide anaerobically, but not aerobically.
