biodegradation of polyacrylamide and its derivatives manufacturer

although polyacrylamide (pam) and its derivatives have many useful applications, their release in nature can have impacts on the environment and human health, thus bioremediation approaches for residual pam are urgently needed. biodegradation of pam and its derivatives has been studied only in the last two decades, with most emphasis on acrylamide biodegradation. microorganisms have been shown

insight into the synergic effect of partially hydrolyzed,production of excess water is one of the main problems leading to declined hydrocarbon production. various techniques, including silicate gel systems, have been developed to manage water production. in this study, factors affecting the na-silicate sealant gel system, containing polymer (phpa) and nanosilica are investigated in terms of gelation time and syneresis. in particular, their

microbial degradation of polyacrylamide and the deamination

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. the carbon backbone, polyacrylate, is

phpa as a key part of polyacrylamide phpa factory with factory price.phpa as a key part of drilling polymer specifically designed to perform in a variety of soil conditions. phpa forms a synthetic membrane on the sidewalls during excavation which controls fluid loss.

What is a polymer flocculant?
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 [ 8, 9, 10 ]. The acrylamide monomer can be used for grafting or crosslinking of other type of polymers.
Are nanocomposite flocculants based on synthetic polymers?
Most of the literature presents, however, nanocomposite flocculants based on synthetic polymers. An example of nanocomposite with using both synthetic and natural polymer is mentioned earlier graft copolymer of polyacrylamide/xanthan gum with silica nanoparticles
Are synthetic polymers effective flocculants?
Synthetic polymers are highly effective flocculants at low dosages but have poor shear stability. In the case of water-soluble polymers, their flocculating effect depends on the size of the random coils (i.e., the radius of gyration), which are the privileged conformation in solution.
What is polyacrylamide?
Polyacrylamide is a term that has various definitions. For our purposes here, we will simply term polyacrylamide as a polymer that contains an acrylamide monomer at some level. Polyacrylamides make up the largest group of polymers in comparison to other synthetic polymeric polyelectrolytes.
