摘要
PROBLEM TO BE SOLVED: To provide a processing method of brine capable of reducing a processing cost by reducing energy necessary for processing brine in a brine concentration method.SOLUTION: The processing method of brine produced by concentrating salt water accompanying processing of desalinating salt water using at least any of a reverse osmotic method and an evaporation method includes: a concentration step of concentrating a part of the brine to obtain concentrated brine and of diluting the other part of the brine to obtain diluted brine; and a salt content-recovering step of recovering a salt content contained in the concentrated brine obtained by the concentration step as a crystalized salt using an evaporation method, where the concentration step includes a membrane separation step of transferring water contained in the brine in a first chamber to the brine in a second chamber through a semi-permeable membrane by flowing a part of the brine to the first chamber of a semipermeable module provided with a semipermeable membrane, and with the first chamber and a second chamber separated by the semipermeable membrane, and flowing the other part of brine to the second chamber to pressurizing the first chamber.SELECTED DRAWING: Figure 1
