Reports Summarize Purification Technology Study Results from Shanxi University (Polyacrylamide-starch composite flocculant as a membrane fouling reducer: Key factors of fouling reduction)

By a News Reporter-Staff News Editor at Journal of Technology -- Investigators publish new report on Purification Technology. According to news reporting originating from Taiyuan, People's Republic of China, by VerticalNews correspondents, research stated, "In this study, two modified starches (CGMS and MGMS) and their corresponding polyacrylamide (PAM)starch composites were studied as membrane fouling reducers for MBRs. The results showed that PAM has positive effects on MGMS but negative effects on CGMS in terms of fouling reduction."

Our news editors obtained a quote from the research from Shanxi University, "These results are likely due to the different effects of PAM on the molecular structures of CGMS and MGMS. Floc size (dp), fractal dimension (df), surface charge, relative hydrophobicity (RH), dynamic viscosity, extracellular polymeric substances (EPS) and soluble microbial products (SMP) were measured systematically to identify the key factors in fouling reduction in these MBRs. The sustainable filtration time was strongly correlated to SMP, dp and df. More importantly, it was observed that fouling reduction was largely dependent on the long-term stability of the flocculations."

According to the news editors, the research concluded: "The PAM-MGMS composite, which demonstrated the longest lasting effect on SMP dp and df, is a promising fouling reducer for MBR operation."
