water soluble polymer flocculants synthesis
flocculants with less than 1% charged functional groups are considered as nonionic flocculants. 34 nonionic flocculants normally have high molecular weights, which helps them flocculate suspended particles through the bridging mechanism. 35 polyacrylamide is the most important water soluble nonionic flocculant because its monomer, acrylamide
synthesis and evaluation of cationic polyacrylamide flocculant,this study addresses the challenge of microalgae harvesting through the development of flocculants. two positively charged cationic polymers including poly[2 (acryloyloxy)ethyl]trimethylammonium chloride (paetac) and poly(3 acrylamidopropyl)trimethylammonium chloride (pamptac) were synthesized using the uv-induced radical polymerization, for harvesting both freshwater and marine microalgae.
optimizing the flocculation effect of cationic polyacrylamide
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. in this paper, the optimal flocculation conditions of a novel cpam were
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
degradation of polyacrylamide and its significance in nature
high quality flocculant polyacrylamide (pam) is commonly used as a flocculant in water and wastewater treatment, a soil conditioner, and a viscosity improver and friction enhancer.
partially hydrolyzed polyacrylamide enhanced oil recovery,polyacrylamide (hpam), are widely used in oil fields to enhance or improve the recovery of crude oil from the reservoirs. it works by increasing the viscos-ity of the injected water, thus improving its mobility and oil recovery. however, during such enhanced oil recovery (eor) operations, it also produces a huge quantity of water alongside oil.

recent achievements in polymer bio-based flocculants for sale
among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (pam)—a non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process. the acrylamide monomer can be used for grafting or crosslinking of other type of polymers.

- 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.
- 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.
- How are polyacrylamides deaminated to polyacrylates?
- Polyacrylamides are first deaminated to polyacrylates by microbial amidases. 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.
