PERFORATED FLUX PIPE FOR FORWARD OSMOSIS OR PRESSURE RETARDED OSMOSIS MODULE COMPRISING THE SAME

摘要

The present invention relates to a porous outlet tube for osmosis and to an osmosis module including same and, more specifically, to a porous outlet tube for forward osmosis or pressure retarded osmosis and to a forward osmosis or pressure retarded osmosis module including same. A bypass tube having a small diameter is concentrically arranged in a central pipe so that the flow of a fluid in the pipe is improved when the bypass tube and central pipe are serially connected and a difference in pressure, which can be caused when the fluid moves to the inside of a forward osmosis or pressure retarded osmosis membrane, can be thereby reduced. The present invention provides a porous outlet tube for forward osmosis or pressure retarded osmosis, the tube comprising: a hollow tube having a plurality of first through-holes and second through-holes which are formed to penetrate therethrough in a length direction so as to enable a fluid to be fed and discharged therethrough; a bypass tube that is concentrically arranged along a length direction inside the hollow tube; and a separation disc that is formed along the edge direction of the bypass tube so as to block a fluid that is fed to the top end of the hollow tube and the other fluid that is fed through the second through-holes.
