Abstract:
1. A system for liquid distillation, the system including: a vapor permeable-liquid impermeable microporous membrane having structures defining a plurality of pores, the vapor permeable-liquid impermeable microporous membrane comprising an anti-microbial material; an oleophobic material, the oleophobic material applied to the structures of the microporous membrane so as to leave the plurality of pores open wherein said oleophobic material is a perfluoroalkyl acrylic copolymer; wherein the vapor permeable-liquid impermeable microporous membrane has a moisture vapor transmission rate (MVTR) of at least 25,000 grams/m means for supplying non-distilled liquid to the first side of the vapor permeable-liquid impermeable microporous membrane; and means for collecting distilled liquid from a second side of the vapor permeable-liquid impermeable microporous membrane.
