Performance of mesoporous adsorbent resin and powdered activated carbon in mitigating ultrafiltration membrane fouling caused by algal extracellular organic matter

This paper focused on the control of ultrafiltration (UF) membrane fouling caused by extracellular organic matter (EOM) extracted from Microcystis aeruginosa through pretreatment with mesoporous adsorbent resin (MAR) and powdered activated carbon (PAC). The influence of MAR and PAC pretreatments on...

Zusammenfassung:	This paper focused on the control of ultrafiltration (UF) membrane fouling caused by extracellular organic matter (EOM) extracted from Microcystis aeruginosa through pretreatment with mesoporous adsorbent resin (MAR) and powdered activated carbon (PAC). The influence of MAR and PAC pretreatments on characteristics of EOM was investigated using molecular weight (MW) fractionation, DAX-8/XAD-4 resin fractionation and fluorescence excitation-emission matrix (EEM) spectroscopy. The results suggested that MAR mainly removed high-MW (>100kDa) fraction of EOM, while PAC primarily adsorbed low-MW (
