Abstract

PURPOSE: To prevent compaction of a reverse osmotic membrance by regulating an operating pressure of penetration in accordance with temperature raise of high- temperature ground water.
CONSTITUTION: A value of operating pressure Pkg/cm2 of a module of reverse oSmotic membranes is set at a value given by specific function on a value of heat distortion temperature T°C and a value of ground water temperature t°C. For example, in a module formed with hollow fiber of cellulose triacetate having 90°C heat distortion temperature T; if the ground water temperature (t) is 40°C, the operating pressure P is set at 64.5kg/cm2; if the temperature (t) is 70°C, the pressure P is set at 34.0kg/cm2.
