Summary:PROBLEM TO BE SOLVED: To provide a reverse osmosis concentration apparatus preventing an abnormal negative pressure from being caused in the tubular membrane type module of a concentration unit, and preventing occurrence of deformation, cracks and breakage causing the performance lowering of a reverse osmosis membrane. SOLUTION: In the reverse osmosis concentration apparatus constituted so that an concentration object is fed to the concentration unit formed by serially connecting the plurality of the tubular membrane type modules, made to flow down in one pass in a high pressure to concentrate by the reverse osmosis process, a back pressure pump is set to a flow path of the concentrated matter at an outlet side of the concentration unit, a first branch path of the concentrated matter is provided at the flow path of the concentrated matter on the upstream side of the back pressure pump, and an air intake valve is mounted to the first branch path.
