molecular mechanisms of ultrafiltration membrane fouling in polymer-flooding wastewater treatment: role of ions in polymeric fouling

Molecular Mechanisms of Ultrafiltration Membrane Fouling in Polymer-Flooding Wastewater Treatment: Role of Ions in Polymeric Fouling

Polymer (i.e., anionic polyacrylamide (APAM)) fouling of polyvinylidene fluoride (PVDF) ultrafiltration (UF) membranes and its relationships to intermolecular interactions were investigated using atomic force microscopy (AFM). Distinct relations were obtained between the AFM force spectroscopy measurements and calculated fouling resistance over the concentration polarization layer (CPL) and

A microblock structure type of anionic flocculant for hematite wastewater treatment: template copolymerization mechanism and enhanced

Synthetic flocculants represented by anionic polyacrylamide (APAM) have attracted more and more attention in the field of wastewater treatment (Desai and Murthy 2012; Ma et al. 2013). The anionic chemical group in APAM can neutralize the positively charged colloidal particles in wastewater and make them destabilized (Zhao et al. 2018 ).
