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
polyacrylamide in wastewater treatment: applications,polyacrylamide (pam) is a high molecular weight polymer that comes in three types: cationic, anionic, and non-ionic. its molecular chain contains a large number of covalent bonds, giving it excellent adsorption properties. as a result, pam is widely used in municipal wastewater treatment, oil extraction, pulp and paper production, and other fields.
polyacrylamide pam flocculants water treatment industrial use
polyacrylamide (pam) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction.dissolved into 0.3% concentration and cross-linking agent added. it can be sprayed on desert to prevent and solidify sand.
current status on the biodegradability of acrylic polymers,abstract acrylic polymers are a diverse group of materials with broad applications, frequent use, and increasing demand. some of the most used ap are polyacrylamide, polyacrylic acid, polymethyl methacrylates, and polyacrylonitrile. although no information for the production of all ap types is published, data for the most used ap is around 9 mt/year, which gives an idea of the amount of
biodegradation of polyacrylamide and its derivatives
the biodegradation of pam and its derivatives are initiated by the enzyme amidase, either under aerobic or anaerobic conditions, and are further degraded partially or completely by an array of different enzymes. future research should focus on elucidating the exact pathways and the enzymes involved in the biodegradation process, especially by
coagulation–flocculation drinking water treatment 1 wiley,the most commonly used procedure for treating surface water includes coagulation, flocculation, settling, filtration and disinfection. this combination of processes is used for treating a wide range of raw water qualities. not only does coagulation–flocculation make it possible to remove turbidity and suspended particles but also to reduce
high quality supplier polyacrylamide
polyacrylamide (abbreviated as pam or pam) 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.

nature‐based coagulants for drinking water treatment
despite the high performance of the conventional coagulants and flocculants used for water purification, their residuals in treated water (e.g., aluminum) are suspected to be linked with neurodegenerative diseases such as alzheimer’s, as well as neurotoxic and carcinogenic effects (camacho et al., 2017).
