PERVAPORATION MEMBRANE SEPARATION METHOD

摘要

To reduce an influence of concentration polarization in a simple structure without an outer membrane element 32 and baffles, reduce a manufacturing cost of a module, and reduce a risk of damaging a membrane surface during manufacture. A plurality of horizontal cylindrical membrane elements 32 are disposed to form a row in a vertical direction in a module main body 11. An inside of each of the membrane elements is depressurized. A treatment liquid is sprayed from above the uppermost membrane element 32 so as to form a falling liquid membrane on outer faces of the respective membrane elements 32.
