  • System for Energy Recovery and Reduction of Deposits on the Membrane Surfaces in (Variable Power and Variable Production) Reverse Osmosis Desalination Systems
    Publication number: 20090152197
    Abstract: A method and a device for desalination, that operates with reverse osmosis membranes (7) and pressure vessels (9) and (20) that are connected to the high pressure circuit via valves (17) and with the low pressure circuit via valves (10). The proposed system includes the operation of a water intake pump (2) and high pressure pump (5) and a circulating pump, when vessel (9) is connected to the high pressure circuit, vessel (20) is fed with fresh salty water in the low pressure, next vessel (20) is connected to the high pressure, vessel (9) is disconnected, then vessel (9) is rinsed, vessel (9) becomes complete with salty water in the low pressure, then vessel (9) is connected in the high pressure, next vessel (20) disconnected, vessel (20) is rinsed, vessel (20) becomes complete with fresh salty water in the low pressure. The process is repeated with alternation of vessels (9) and (20).
