A reverse osmosis water purification system comprises an impulse turbine operatively connected to a source of water to be purified. A feed pump is connected to the impulse turbine to supply a source of high pressure water to be purified. A first purification membrane chamber is connected to the feed pump to receive a supply of high pressure unpurified water from the feed pump. The first purification membrane chamber has an outlet for discharging purified water and a discharge opening for discharging high pressure unpurified water. A hydraulic turbocharger has a turbine end T and a pump end P. The pump end P has an inlet for receiving the high pressure unpurified water from the first purification membrane chamber and an outlet which discharges the high pressure unpurified water. A second purification membrane member chamber is connected to the outlet of the pump end P of the hydraulic turbocharger for receiving the high pressure unpurified water. The second purification-membrane chamber has an outlet for discharging water purified in the second purification membrane chamber. The second purification membrane chamber has a discharge opening for discharging high pressure unpurified water from the second purification membrane chamber. The discharge opening is connected to the turbine end T of the hydraulic turbocharger and a turbine end T of the impulse turbine. The high pressure unpurified water from the second purification membrane chamber can be used to drive the turbine end T of the impulse turbine and/or the turbine end T of the hydraulic turbocharger to increase the pressure of the water to be purified that is supplied to the first or the second purification membrane chambers.
