Figure 4

Separation of oil-in-water emulsions with the mineral-coated membranes.

(a) Time-dependent flux and rejection ratio of the mineral-coated membranes during emulsion separation (diesel-in-water, 1:100 v:v). The filtration contains three cycles and every cycle includes two steps: water filtration and emulsion filtration. Before the third cycle, the membrane sample was re-mineral coated with 3 cycles. (b) Separation performances of the mineral-coated membranes for a range of oil-in-water emulsions (1:100 v:v). The trans-membrane pressure used is 0.05 MPa during emulsion separation.
