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. This article first appeared in the August/September 2010 issue of Desalination & Water Reuse magazine.
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. This article appeared in D&WR magazine's February/March 2009 issue.

Another forward-osmosis process has taken a step forward. QuantumSphere Inc filed for a US patent on 14 January 2009 for its water purification process, which, it claims, serves as a more energy-efficient alternative to desalination methods now commonly used.
Combining Forward Osmosis with Reverse Osmosis
A combination of forward osmosis with reverse osmosis could facilitate the treatment of some high fouling wastewaters. The system uses brine to draw water from the wastewater without high pressure or turbulence. Key element is the membrane's ability to allow rapid passage of water without much internal concentration polarization. The diluted draw solution can then be desalinated by reverse osmosis. The Two-Way Osmosis or TWO system may also be usable in very remote areas, where seawater ponds can be built for evaporative recovery of salt. Catalyx is designing a pilot system (patent pending) to desalinate seawater without external electric power. This article was published in the May/June 2009 issue of Desalination & Water Reuse.
