Permeance versus operating time of the PSF/EVOH blend membrane and PSF/EVOH/HNTs MMMs during the fouling and cleaning operating process (phases I, III, V, and VII: pure water filtration and II, IV, and VI: BSA permeation. Each phase was run for 60 min) (a) and permeance recovery rate (PRR) of blend membranes for the treatment of BSA and oil-in-water emulsion (b), Separation mechanism of the PSF/EVOH HNTs MMMs for highly efficient oily emulsion and BSA separation (c). The error bars display the data’s standard deviation from three independent tests.
