148     5 Membranes in Chiral Separations


               processes are the ease of staging (this applies especially to the liquid–membrane
               fractionation) and the ease of treating large streams (which is a key advantage of the
               MEUF process). In the near future, we expect more of these “hybrid” technologies
               to be developed, which will certainly broaden the scope of membrane-based enan-
               tioseparations.
