Abstract

Abstract

In this research, the XDLVO (extended Derjaguin-Landau-Verwey-Overbeek) theory was employed to analyze the fouling status of nanofiltration (NF) membrane caused by hydrophilic and hydrophobic organic matters. Quantitative analysis was conducted on six types of hydrophilic and hydrophobic organic matters with different molecular weight ranges (less than 100 kDa, less than 50 kDa, and less than 3 kDa, respectively) and the interfacial free energy of NF membrane was analyzed, in a bid to figure out the performance of the membrane fouling. Furthermore, the corresponding relationship between flux decay and interfacial free energy was verified by the NF experiment. The results showed that the degree of membrane fouling caused by the above-mentioned six hydrophilic or hydrophobic organic matters with different molecular weights in this study was consistent with the XDLVO theoretical analysis, in which the hydrophobic ones with a molecular weight less than 100 kDa showed the slightest repulsive interaction against the membrane and led to the most serious fouling. Besides, the degree of NF membrane fouling by different organic matters was ordered in a descending way as follows:(hydrophobic, molecular weight less than 100 kDa)>(hydrophobic, molecular weight less than 50 kDa)>(hydrophobic, molecular weight less than 3 kDa)>(hydrophilic, molecular weight less than 3 kDa)>(hydrophilic, molecular weight less than 50 kDa)>(hydrophilic, molecular weight less than 100 kDa). The main contaminants on the membrane surface were polysaccharides, proteins and phencyclic olefins, the organic matter clogged the membrane pores in the early stages of filtration, resulting in a rapid decrease in the specific flux of the membrane, while the formation of a cake layer in the later stages of filtration slowed the decrease in the specific flux of the membrane.
