RECLAMATION OF FRACKING WATER HAS DRAWBACKS

The Karoo is a water deprived area similar to some parts of the US such as Texas where fracking is in progress. The water-stressed areas in the United States have already been under pressure to successfully manage scarce water resources for years prior to the advent of fracking. As a consequence fracking companies in states…

NEW SYSTEM FOR REUTILSATION OF OLD RO MEMBRANES

According to Desalination Volume 320, 1 July 2013, Pages 49–55, researchers at Sichuan University in China have designed a new system for chemical cleaning and repair of used reverse osmosis membranes (CCR-ROM), which system uses fewer chemical reagents and produces less waste water. The results indicate that the average salt rejection of the cleaned membranes…

CHEAP SEAWATER DESALINATION ON THE HORIZON

The common method of desalinating sea water is through Reverse Osmosis (RO) which relies on expensive and easily contaminated membranes which process consumes a lot of expensive energy. But now a team of researchers from the University of Marburg, Germany, and the  Universiy of Texas at Austin have developed a new water desalination process they say…
