The removal of disinfection by-products (DBPs) by extractive membrane process
An extractive membrane process was used to remove trihalomethanes from a simulated water sample. A PVDF hollow fiber UF support membrane was coated with polydimethylsiloxane (PDMS), which served as the active membrane extraction layer. The partition coefficients of chloroform (Kp =48.15) and bromoform (Kp =84.34) were determined by a simple adsorption test. A resistance-in-series model was adapted to determine the limiting factors of the system. The membrane resistance for bromoform, which has a high Kp value was minimal and therefore, mass transfer is more affected by the film boundary layer resistances between the membrane and solution interface. Contrastly, the extraction performance of chloroform, which has a lower Kp value was more affected by the membrane resistance.
