The feed spacer on a spiral wound RO membrane is intended to develop for vortexes for prevention of localized salt concentrations to reduce scaling and generous openings to minimize fouling. A thin feed spacer will allow an increase the membrane area in a standard 8? element which will allow greater water production in that same membrane element. T...

Aqua Membranes has developed membrane feed spacers printed directly on the membrane surface. These spacers are thinner than conventional mesh spacers and allow up to twice as much membrane surface in a standard size element. The spaces can have any shape and are more "open" in design which reduces membrane fouling and making them easier to clean....

Conventional plastic mesh material has been utilized as the feed spacer between spiral wound membranes sheets since they were invented. Under a grant from the Defense Advanced Research Projects Agency (DARPA) printed feed spacer technology was developed. Aqua Membranes Inc. was started in 2011 to commercialize this technology and has subsequently a...
