METHOD FOR CONCENTRATING SOLUTE-CONTAINING AQUEOUS SOLUTION AT HIGH CONCENTRATION BY REVERSE OSMOSIS METHOD IN NON-OSMOTIC PRESSURE DIFFERENCE STATE

摘要

The present invention relates to a method for concentrating an aqueous solution with low pressure in a non-osmotic pressure difference state and, more specifically, to a method for concentrating a solute-containing aqueous solution to be concentrated with low pressure in a non-osmotic pressure state. When the method of the present invention is used, energy consumption is reduced, and the aqueous solution can be concentrated, without using an extraction solution, until the saturated aqueous solution of the maximum solute is prepared or the concentration of the solute is 100%. In addition, the method has an advantage of not requiring the use of a separate osmotic induction solution.
