Purpose and goal

Fouling is one of the major challenges in the membrane industry since it is associated with downtime, use of water and cleaning Chemicals, and reduction in membrane life. A new generation of membranes with anti-fouling capability can cause a revolution in technology impact. By inclusion of 1 w t% of graphene oxide (GO) during the fabrication of the membrane, increased hydrophilicity, optimized pore size and mechanical properties, as well as rejection of major fouling component such as extracellular polymeric substances (EPS), and microorganisms can be achieved.

Expected results and effects

Tyhe use of the novel anti-fouling membrane will allow higher flux, reducing both investment and cost of operation. Use of these novel anti-fouling membranes support several of the environmental objectives: - Reduced trans-membrane pressure and efficient separation which will lower consumption of resources: Reduced Climate Impact and Fresh Air. - Reduce emissions of toxic substances: Non-toxic Environment. - Reduced emissions of eutrophying substances: Zero Eutrophication and Seas in Balance.

Planned approach and implementation

The project will develop anti-fouling membranes for targeted applications chosen from the following categories 1) the chemical, iron & steel and engineering industry process- and waste water, 2) improved treatment (including recycling) of municipal waste water, 3) landfill leachate and contaminated areas, 4) flue gas condensate. The GO-membranes will be made using commercial GO and GOhybrids. Long term testing in at least two of applications, evaluating the flux and the retention.
