polyacrylamide degradation in oil field wastewater treatment uv/h,this study investigated polyacrylamide (pam) degradation by uv/hydrogen peroxide (h 2 o 2) and uv/potassium peroxydisulfate (pds) in pure water and practical oil field wastewater. based on a previously developed mini-fluidic photoreaction system that is easy to operate and requires low sample volumes, an experimental setup for rapid evaluation
water soluble polymer flocculants synthesis
polymer adsorption can occur through hydrogen bonding (polyacrylamide on silica silanol groups), electrostatic interaction (cationic polymers on negatively charged sludge), hydrophobic interaction (poly(vinyl alcohol) on silver iodide), and ion bridging (anionic polyacrylamide on negatively charged clays with the help of divalent calcium ion). 7
microbial degradation of polyacrylamide and the deamination.in this work, we review the publicly available literature on the microbial degradation of polyacrylamide and its deamination product polyacrylate. to our knowledge, biotic polyacrylamide degradation has been described only very briefly in two recent reviews (guezennec et al., 2015; joshi and abed, 2017). we begin our work by discussing the

- Where to buy polyacrylamide flocculant polymer powder?
- Where to Buy Wholesale Polyacrylamide (PAM) Flocculant Polymer Powder, Being Useful In the Purification and Treatment of Water, Gas, Air, Gold, Food Beverage . Yongruida Is Your Best Supplier for Polyacrylamide Flocculant Solutions.
- What is cationic polyacrylamide used for?
- Cationic polyacrylamides (CPAM) are used for emulsion breaking, and for promoting filtration and sludge dewatering. Another common use is oil extraction and recovery. When water is injected into the well, PAM assists in pushing oil locked in reservoirs towards the pump by increasing the viscosity of the injected water.
- What is a polyacrylamide polymer?
- Polyacrylamide, also briefly referred as PAM, Polyacylamides are high molecular weight water soluble or swellable polymers formed from acrylamide or its derivatives.The polymer can be synthesized as a simple linear chain or as a cross-linked structure.
- What is polyacrylamide used for?
- Polyacrylamide (PAM) is commonly used as a flocculant in water wastewater treatment, pulp and paper production, agriculture, food processing and mining. which is based on polyacrylamide copolymers providing the complete range of ionicities and molecular weights necessary to meet optimal performance for each applications.
