Scientist from Ghent University in Belgium have recovered 1,000 litres of drinkable water over a 10-day event using a solar-powered machine, Engadget reported.
Their membrane distillation machine was deployed at a music and theatre festival, and according to the scientists the experiment was a success.
Engadget reported that the water recovered will be used in the brewing of Belgian beer.
The research showed that up to 95% of all ammonia present in hydrolyzed urine could be recovered by increasing its pH to 10.5 or higher within a period of 2 hours.
It further showed that at least 75% of the available water could be recovered from non-hydrolyzed human urine without process failure.
