Making drinking water

Try making drinking water with nothing more than plastic, sea water and lots of sun. It sounds like an assignment from a survival programme, but access to safe drinking water is a daily concern for 750 million people. Dr Rajat Bhardwaj saw the need at first hand when he taught in a slum area in Mumbai. He was determined to develop technology that would enable people to make their own safe drinking water. The chemical engineer developed a water filter at the company Dr. Ten and obtained his doctorate under the supervision of Prof. Rob Mudde (Faculty of Applied Sciences) on the subject of an inflatable water dome in which salt water evaporates before condensing into drinking water.
