An apparatus for separating a liquid by pervaporation, which comprises at least one pervaporation membrane module unit for purifying a liquid to be treated, a supply line connected to said pervaporation membrane module unit for supplying the liquid to be treated to the membrane module unit, a withdrawing line for withdrawing the permeated fluid from the membrane module unit and a withdrawing line for withdrawing the non-permeated liquid, wherein said supply line is provided with a pressure pump for transporting the liquid and a heater, and the final withdrawing line for the non-permeated liquid is provided with a pressure regulating valve.

Apparatus for separating a liquid mixture by pervaporation

A hydrophilic drying liquid such as isopropyl alcohol is evaporated and supplied to an object to be dried such as an electronic component. As the drying liquid is condensed on the surface of the object and flows down together with water adhering to the object, the object is dried. Water contained in the condensate is removed by means of a membrane-type separator disposed in the liquid or vapor of the drying liquid. A rise in the water concentration in the drying liquid is prevented so as to maintain high drying efficiency.
