    Abstract: According to one embodiment, a power recovery device is used in an apparatus in which firstly pressurized raw water (FPRW) is supplied to a reverse osmosis membrane unit to extract fresh water and condensed and depressurized raw water (HPB) remains. The device recovers the energy of HPB, rises a pressure of raw water (LPF) by using the recovered energy, and adds such secondly pressurized raw water (HPF) to the FPRW. The device accommodates a fixed center shaft and a rotary member on the shaft in a housing. LPF flows into one paired chambers of the housing and radial channels of the member to push and rotate the member, and HPB is introduced into the channels through paired openings of the shaft to push out LPF as HPF from the channels and another paired chambers of the housing.
