isolation and characterization of polyacrylamide-degrading,polyacrylamide (pam) is a water-soluble polymer that is widely used as a flocculant in sewage treatment. the accumulation of pam affects the formation of dewatered sludge and potentially produces hazardous monomers. in the present study, the bacterial strain hi47 was isolated from dewatered sludge.

chemical polyacrylamide (PAM) flocculant types,selecting the appropriate pam for your application involves considering several factors: understanding sludge source: identify whether the sludge is organic or inorganic in origin. generally, cationic pams are used for organic sludge, while anionic pams are used for inorganic sludge.
flocculants and the science behind clean drinking water
in the new from turbid to clear: how flocculation cleans up drinking water science project, students take a closer look at one of the key processes water from surface sources like lakes and rivers undergoes in a water treatment plant—the use of flocculants to remove solid debris and particles.

microbial degradation of polyacrylamide and the
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.

chemical polyacrylamide water treatment polymer
polyacrylamide (abbreviated as pam or paam) is a polymer with the formula (-ch 2 chconh 2-). it has a linear-chain structure. pam is highly water-absorbent, forming a soft gel when hydrated. in 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries.
- What is the difference between cationic and anionic polymerization?
- The main difference between cationic and anionic polymerization is that cationic polymerization is initiated by a cationic species, whereas anionic polymerization is initiated by anionic species. Polymerization is a chemical process in which small molecules called monomers react with each other to form long chains or networks known as polymers.
- Can cationic polymers be used outdoors?
- Some types of anionic polymers like epoxys cannot be used outdoors due to their poor UV resistance which causes yellowing. Overall, cationic polymers tend to be more versatile for acrylics than anionic polymers due to their positive charge and properties.
- Can cationic polymerisations be enhanced by living methods?
- Like cationic polymerisations, anionic polymerisations can be greatly enhanced through the use of living methods. Problem SM4.1. Anionic polymerization of p -substituted styrene proceeds very well when the substituent is an electron-withdrawing group such as nitrile. Explain the reason for the success of this approach.
- Why are cationic polymers not widely used?
- In this reaction, a cation (an ion with a positive charge) transfers its charge to a monomer to form the positively-charged polymer, which consequently grows by reacting with other monomers. Cationic polymers are not used as widespread, because there are only a few polymers that can successfully execute cationic polymerization.
