NematiQ announces commercial-scale graphene membrane milestone achievement

NematiQ (a 100% subsidiary of CleanTeq Water) announces commercial-scale graphene membrane milestone achievement
NematiQ, an Australia-based developer of graphene oxide (GO) membranes for water treatment applications, has reported commercial-scale manufacture of an innovative graphene membrane.

Over the last five years, NematiQ has developed a patented, layer-by-layer methodology to produce the graphene membrane. NematiQ has achieved a milestone by producing more than 1,000 meters worth of 1,000-millimetre-wide flat sheet graphene membrane, at speed, on an industrial roll-to-roll coating machine, showcasing its ability to manufacture graphene membrane at a commercial scale.

NematiQ’s graphene membranes will be converted into spiral-wound cartridges that can be incorporated into demonstration plants — the final step before commercial sales of the membranes can begin.

Essentially, graphene membranes are designed to remove bacteria, virus and dissolved organic compounds without removing the salts.

Some of the benefits of the graphene membrane include less energy use, high water recovery and less by-product.

Graphene membranes also have anti-fouling properties and so use considerably less chemicals to clean than the commonly used polymeric membranes.
