To prevent a pressure drop in a semipermeable membrane module used in a brine concentration (BC) from increasing, in a concentration system using the BC.SOLUTION: There is provided a concentration system comprising: a semipermeable membrane module that comprises a semipermeable membrane, and a first chamber and a second chamber separated by the semipermeable membrane, transfers water contained in a first object liquid present in the first chamber to a second object liquid present in the second chamber via the semipermeable membrane, and discharges a concentrated liquid from the first chamber and discharges a diluted liquid from the second chamber, by allowing the first object liquid to flow to the first chamber at a specified pressure and allowing the second object liquid to flow to the second chamber at a pressure lower than the specified pressure; and a temperature controller that controls a temperature of the first object liquid being fed into the first chamber.SELECTED DRAWING: Figure 1 【課題】ブラインコンセントレーション（ＢＣ）を用いた濃縮システムにおいて、ＢＣに用いられる半透膜モジュールにおける圧力損失の上昇を抑制すること。【解決手段】半透膜と、前記半透膜で仕切られた第１室および第２室と、を有し、第１対象液を所定の圧力で前記第１室に流し、第２対象液を前記所定の圧力よりも低い圧力で前記第２室に流すことで、前記第１室内の前記第１対象液に含まれる水を前記半透膜を介して前記第２室内の前記第２対象液に移行させ、前記第１室から濃縮液を排出し、前記第２室から希釈液を排出する、半透膜モジュールと、前記第１室に供給される前記第１対象液の温度を制御する、温度制御装置と、を備える、濃縮システム。【選択図】図１
