Abstract

INTEGRATED REVERSE OSMOSIS MODULE WITH ENERGY RECOVERY FOR DESALINATION Disclosed herein is an integrated reverse osmosis and energy transfer system that contains a first fluid inlet; a single reverse osmosis membrane module having a permeate outlet and a first and second fluid inlet/outlet channel in fluid communication with the first fluid inlet; and an energy transfer system having a second fluid inlet, a brine outlet, a first energy exchanging module and a second energy exchanging module, each energy exchanging module is in fluid communication with the second fluid inlet and the brine outlet in an expulsion flow phase and in fluid communication with the first and second fluid inlet/outlet channels of the single reverse osmosis membrane module in an energy recovery flow phase, wherein the first and second energy exchanging modules are adapted to reversibly operate in opposite flow phases where the flow direction for the expulsion flow phase in each energy exchanging module is constant and where the flow direction for the energy recover flow phase in each energy exchanging module is constant, and the single reverse osmosis membrane module is adapted to reversibly receive a feed flow through one of the first and second fluid inlet/outlet channels and produce a brine outflow through the other of the first and second inlet/outlet channels, as well as continuously producing a permeate flow that exits through the permeate outlet. Also disclosed herein is a method to use said system in reverse osmosis. FIG.A 16
