HYBRID MODULAR SYSTEM OF STATIC CHAMBERS WITH VIRTUAL ROTATION FOR SAVING ENERGY IN REVERSE-OSMOSIS DESALINATION

摘要

Hybrid modular system of static chambers with virtual rotation for saving energy in reverse-osmosis desalination of the type that comprise a membrane-osmosis installation where the sea water is separated into desalinated water and waste brine at high pressure, which is forced through one or more pressurisable tubular chambers. The system comprises a series of unitary elements each of which has a conventional tubular chamber with two non-return valves at one end and on the other end a three-way piston or membrane pilot-operated valve is installed and actuated by the pressure of the waste brine coming directly from the membrane. The unitary elements are supervised and controlled by an electronic device that manipulates the valves to create a sequence that, without having to physically rotate the chambers, causes the water flows to behave in exactly the same way they would in a conventional rotary-chamber system.
