Abstract

A feed channel spacer for a spiral wound membrane element has Inlet and outlet edges that are thinner than the rest of the spacer material. The edges may be made thinner, for example, by passing the edges of a sheet of feed spacer material through a pair of hot rollers or by compressing the edges of the sheet in a heated press. The thinned edges of the feed spacer material are located in the element between glue lines applied to the permeate spacers of the element. The thin edges allow a greater membrane surface area to be provided in a given element diameter. A feed channel spacer may also have an area with obstructions to create micro-mixing effects. These obstructions may be provided on a feed spacer sheet of constant thickness, or one with thin edges.
