Using solar energy to purify water

solar, energy, purify, water, Petra Wadström

Inventor Petra Wadström has developed Solvatten, an environmentally friendly system that makes unsafe water drinkable using solar energy

Solvatten combines heat, UV and a built in filter in a specially designed container to clean contaminated water by filtrating macro-organisms which cause diseases.

Half a billion people heat and treat their water by boiling it, using charcoal, kerosene or firewood. Solvatten is solar powered and can reduce use of these fuels. The portable 10-litre container is filled and placed in the sun. The hot water is used for hygiene and cooking, or cooled in the shade for drinking.
