Abstract: The present invention relates to a method of concentrating an aqueous solution by low pressure under a zero osmotic pressure difference condition, and more particularly to a method of concentrating a solute-containing aqueous solution by low pressure under a zero osmotic pressure difference condition. When the method of the present invention is used, there are advantages in that energy consumption is low, and an aqueous solution can be concentrated until it can reach the maximum solute concentration or a solute concentration of 100%, without having to use an extraction solvent. In addition, there is an advantage in that the need to use a separate osmotic pressure draw solution is eliminated.
