cationic polyacrylamide copolymers (pam): environmental half

background cationic polyacrylamide copolymers (pam) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. concern has been expressed since little is known about the degradation of pam in soils. to obtain detailed information on the polymer’s fate in the soil compartment, the degradation of 14c

best practices guidance for the use of anionic polyacrylamide,pam aids solid-liquid separation by causing suspended particles to bind and form larger aggregates. the process is known as polymer bridging. one of the most common polymer flocculants on the market. common uses of pam as a flocculant: reduction of sediment and nutrient loads to natural lakes and ponds.

towards sustainable management of polyacrylamide in soil

whether non-ionic pam (npam), anionic pam (apam) or cationic pam (cpam), numerous examples have been reported for use in wastewater purification (junqua et al., 2015). however, flocculants carrying a charge can assist in attracting and binding particles through charge neutralization, providing aid in the flocculation process (yu et al., 2015

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.
Does polyacrylamide biodegradation accumulate acrylamide monomers?
The biodegradation did not accumulate acrylamide monomers. Based on the SDS-PAGE and N -terminal sequencing results, the PAM amide groups were converted into carboxyl groups by a PAM-induced extracellular enzyme from the aliphatic amidase family. Keywords: polyacrylamide, biodegradation, dewatered sludge, microorganisms 1. Introduction
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.
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.
