The purpose of the feed spacer is to provide space for water to flow between the membrane surfaces, and to allow for uniform flow between the membrane leaves. Next, the permeate spacer is attached to the permeate tube, and the membrane sandwich prepared earlier is attached to the permeate spacer using glue.

The next permeate layer is laid down and sealed with glue, and the whole process is repeated until all of the required permeate spacers have been attached to the membranes.

The finished membrane layers then are wrapped around the tube creating the spiral shape. Currently, Synder offers nearly 30 various nanofiltration, ultrafiltration and microfiltration membranes for specialty process applications worldwide. Construction Spiral-wound elements consist of membranes, feed spacers, permeate spacers, and a permeate tube.

Feed spacer is then put in between the folded membranes, forming a membrane sandwich. Browse SUEZ spiral wound membrane elements.
