Bacteria and nanofilters -- the future of clean water technology
Date:2/22/2008

branes are also being used in work funded by the Middle East Desalination Research Centre, which looks at creating drinking water from seawater. By pre-treating the seawater and removing contaminants, the membranes reduce the fouling of machinery in the next stage of the process whether through reverse osmosis or thermal desalination. This can prevent damage to the machinery, reducing the need for expensive repair and replacements.

And by measuring liquid properties at the nanoscale, using state-of-the-art atomic force microscope equipment at the University, researchers are exploring how liquids behave at an atomic level how they flow and pull apart. These results could be used in mechanics and industry, for example, maximising the use of oil in an engine.

Liquids are also being tested at a range of temperatures, from the very low (-50 oC) to the very high (150 oC).

Professor Hilal said: Examining the properties of liquids has never been done before at this scale.

By using bioremediation and nanofiltration technology combined, the water cleaning process is integrated using far less energy than current processes. Add to this the recycling of waste products as fuels and you have a greener technology.
