Abstract

PURPOSE: To make possible prolonged separation of solution by reverse osmosis separation in combination with a multistage solution separating method or a circulating solution separating method to prevent propagation of microorganisms in the raw liquid by means of a germicide.
CONSTITUTION: This relates t a reverse osmosis separation device or a solution separator such as an ultrafilter in which the propagation of microorganisms is a caused during the passage of the raw liquid due to a nutritive substance contained in the liquid, thereby posing the problem of a deterioration in performance. Solution separating devices 1 are arranged by multi-stages so that permeated liquid and/or concentrated liquid separated by the slution separating device on each stage (the latter is illustrated) is further treated with the subsequent one through a extraction tube 2. In addition, a germicide is added to a raw liquid feed pipe 5 and a piping between respective separating devices 1.
