Water scarcity will be aggravating significantly in the near future (UN Water report) which generates the pressing need to efficiently produce drinking water through, for example, desalination. Membrane separations offer in principle a cost-efficient solution compared to thermal processes but may severely suffer from fouling of the membrane. Surphase offers the possibility to minimise the detrimental effects of membrane fouling. The disruptive and patented technology of Surphase finds its application not only in the production of drinking water but also other sectors with stringent exigencies of water quality, such as Oil&Gas, health, and the pharmaceutical industry.
