  • 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 [ , , ].
  • Does pH variation influence the membrane fouling caused by APAM?
  • The main goal of the research was to determine how pH variation influences the membrane fouling caused by APAM. The effects of pH on the surface physicochemical properties and surface energies of a polytetrafluoroethylene (PTFE) membrane and the APAM, as well as on the membrane flux and filtration resistances, were investigated.
  • How does Apam interact with PTFE membrane?
  • During the whole MF process, APAM molecules directly interacted with the original PTFE membrane in the initial phase. In the later phase, however, the PTFE membrane was fully covered by APAM, and the APAM molecules interacted with the fouled membrane.
  • What is the correlation coefficient (R2) for Apam PTFE membrane?
  • In the initial and later phases of the MF process, the correlation coefficient ( R2) values for the linear fitting of K and UTOT for the APAM–PTFE membrane and APAM–APAM were 0.708 and 0.792, respectively.
