Abstract

PURPOSE: To maintain the performance of a permselective membrane consisting of cellulose ester and to improve the sterilizing property and the removability of a preserving agent by washing by filling an aq. soln. contg. sodium hydrogen sulfite and a polyhydric alcohol in specified concn. into the titled fluid separator as a preserving liq.
CONSTITUTION: An aq. soln. contg. 10mg/lW14,000kg/l sodium hydrogen sulfite and 0.5W25% polyhydric alcohol such as glycerin is used as a keeping liq. The preserving liq. is filled in a fluid separator such as an element and a module composed of a permselective membrane consisting of cellulose triacetate, etc., when the separator is stored and transported.
