Comparative study of anion polyacrylamide (APAM) adsorption-related fouling of a PVDF UF membrane and a modified PVDF UF membrane

The high-molecular-weight anionic polyacrylamide (6880 kDa) adsorption related fouling of a virgin PVDF membrane (OM) and a modified PVDF membrane (MM) were investigated via analysis of particle size distribution, structure of membranes, influencing factors, SEM, and ATR-FTIR.

analysis of anion exchange membrane fouling mechanism caused by anion polyacrylamide in electrodialysis

Analysis of anion exchange membrane fouling mechanism caused by anion polyacrylamide in electrodialysis

Mechanism of AEM fouling by APAM during ED is thoroughly analyzed. ? Voltage¨Ctime curves during ED processes are investigated. ? A gel layer is formed on diluate side of the AEM after fouling. ? AFM is utilized to investigate the interaction forces. ? Electrostatic interaction dominates the interactions between membranes and APAM. Abstract

fouling dynamics of anion polyacrylamide on anion exchange membrane in electrodialysis

Fouling dynamics of anion polyacrylamide on anion exchange membrane in electrodialysis

Abstract Anion polyacrylamide (APAM) fouling towards anion exchange membrane (AEM) during electrodialysis (ED) of industrial effluent draws recent attention. The fouling dynamics was herein investigated via different approaches in monitoring the variation of the solution and membrane properties.

Minerals | Free Full-Text | Effect of Agitation on the Dissolution of APAM with Different Molecular Weights and the Equivalent Diameter of

To solve these problems, firstly, mechanical stirring dissolution tests are carried out on anionic polyacrylamide (APAM) with different molecular weights to explore the stirring dissolution law of APAM with 3¨C25 million molecular weights. Results indicated that the optimal stirring speed of APAM with 3¨C6 million molecular weight is 800 r/min.
