“Researchers from Pennsylvania State University have developed technology that treats waste water and generates energy at the same time – two priorities for Middle Eastern municipalities. Combining Reverse Electrodialysis (RED) technology developed in the Netherlands and Norway, which harvests energy where fresh water and sea water meet, with Microbial Fuel Cells (MFC) that use organic matter to create an electric current, Professor Bruce Logan and his team have found the ultimate solution for developing countries that have limited access to water and power.

Where fresh water and salt water meet

RED technology involves placing fresh water and salt water in intermittent chambers of a fuel cell which are separated by membranes and then create an electrochemical charge, but Penn State researchers told the BBC that this technology has limitations.”

“A small Victorian company reckons it has found a way to prevent 3.5 million deaths a year from water-borne diseases while also cutting emissions of the greenhouse gas carbon dioxide.

“F CUBED, based in Somerton, has been working on its solar-powered desalination system for about six years and started selling the units commercially in November.

“The modular unit, which retails for $362.50 plus GST and freight, works by running saltwater through a gravity-fed pipe at the top.

“The water disperses evenly as it runs down the solar collector evaporator. The solar power heats the water, which vaporises and then condenses on the inside of the plastic panel enclosure. The distilled water runs to the bottom of the unit where it is collected.

“In the process, disease-causing pathogens, as well as heavy metals, are removed.

“Peter Johnstone, the chief executive and founder of F CUBED, said there was enormous potential to work with developing countries to provide clean drinking water.”
