Aquaporin-embedded membranes to fight water scarcity
Biomimetics - nature-inspired innovation - is one of the emerging technologies racing to become the first to effectively bring down the energy costs of desalination. Several groups and companies around the world are working on copying nature s method of transporting pure water across a membrane. One of them is Denmark-based Danfoss AquaZ A/S and its subsidiary Danfoss AquaZ Inc in Cincinnati/Ohio, which is striving to incorporate functional aquaporin water channels into revolutionary new and cost-effective desalination membranes.

Large Diameter RO Desalination Elements
In recent years, increasing the diameter of spiral elements has been studied as a method of lowering the cost of membrane treatment. It has been shown that the installed cost of a reverse osmosis (RO) plant can be reduced by up to 27% using larger diameter elements.Large diameter elements provide savings in footprint and building costs, as well as savings in the number of connections, to reduce the installed cost of a brackish water RO or nanofiltration (NF) system. This article presents case studies where large diameter reverse osmosis (RO) elements were used, including the reasons why large diameter elements were selected for specific projects. Systems desalinating brackish groundwater for potable water supply in the United States include the City of Goodyear, Arizona; the City of Waupun, Wisconsin; and the Tate-Monroe Water Association of Ohio. In Australia, the Bundamba AWT Plant in Queensland treats municipal effluent for reuse. At Joe White Maltings, an integrated membrane system, combining a membrane bioreactor (MBR) and an RO system, allows wastewater from the plant to be recycled.
