FLOW CHANNEL MATERIAL FOR FORWARD OSMOSIS MEMBRANE SEPARATION, SEPARATION MEMBRANE UNIT, AND SEPARATION MEMBRANE ELEMENT.

摘要

Provided is a flow channel material for forward osmosis membrane separation, which provides a good agitation effect and a favorable pressure loss property in the vicinity of a membrane surface in forward osmosis membrane separation even in the case where the flow channel is of rectilinear configuration. Another purpose of the present invention is to provide a separation membrane unit, a laminate thereof, and a separation membrane element using the same, all of which provides a good agitation effect and a favorable pressure loss property in the vicinity of the membrane surface in forward osmosis membrane separation, and which further enable easy production of a separation membrane laminate, are easy to handle, and allow a flow channel to be formed in a simplified structure. The flow channel material for forward osmosis membrane separation according to the present invention has a thickness t of 0.1-1.0 mm and has a network-patterned structure comprising resin fibers 13a, 13b oriented in two directions in which the resin fibers 13a, 13b intersect with each other at an intersection angle α of 40-90 degrees.
