  • Is anionic Polyacrylamide a model foulant for gel formation process?
  • Anionic polyacrylamide was used as a model foulant for gel formation process in various ultrafiltration processes by two kinds of ultrafiltration membrane, e.g., polyvinylidene fluoride (PVDF) membrane (OM) and TiO 2 /Al 2 O 3 -PVDF membrane (MM); then, a gel formation model was established and systematically assessed.
  • What is polyacrylamide polymer gel treatment?
  • They include polymer flooding, alkaline-surfactant flooding, foam flooding, gel treatments, and so on. Among these methods, polyacrylamide polymer gel treatment is a common and cost-effective method because the process can reduce water cut by sealing the thief zone and redistributing the water drive.
  • Why is anionic polyacrylamide chosen?
  • Anionic polyacrylamide is chosen because the intramolecular electrostatic repulsion between polymer segments forces the polymer chains to adopt a more extended conformation, increasing the efficiency of bridging flocculation.
  • What are the different types of anionic polyacrylamide synthesis technologies?
  • The paper lists six different kinds of anionic polyacrylamide synthesis technologies, including homopolymerization posthydrolysis process, homopolymerization cohydrolysis process, copolymerization approach, inverse emulsion polymerization, precipitation polymerization and radiation polymerization.
