Belgian scientists make novel water-from-urine machine

Reuters:  A team of scientists at a Belgian university say they have created a machine that turns urine into drinkable water and fertilizer using solar energy, a technique which could be applied in rural areas and developing countries.

While there are other options for treating waste water, the system applied at the University of Ghent uses a special membrane, is said to be energy-efficient and to be applicable in areas off the electricity grid.

"We're able to recover fertilizer and drinking water from urine using just a simple process and solar energy," said University of Ghent researcher Sebastiaan Derese.

The urine is collected in a big tank, heated in a solar-powered boiler before passing through the membrane where the water is recovered and nutrients such as potassium, nitrogen and phosphorus are separated.  Cont'd...
