  • 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 is anionic polyacrylamide (Apam)?
  • 1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [ , , ].
  • Is there mechanical stirring in a hydrolyzed polyacrylamide reactor?
  • There is no mechanical stirring in the reactor. ... ... Partially hydrolyzed polyacrylamide (HPAM) is the most widely used water-soluble non-toxic polymer in water treatment (Zheng et al., 2013), paper mills (Wong et al., 2006), ore processing and crude oil production processes (Pei et al., 2016).
