Solar Energy Water Purification Plastic Sack To Reduce Diseases In Rural Africa

Access to a clean source of drinking water is a major problem in many developing countries. Villagers often have to cover long distances in search for drinking water. While African leaders are struggling without any means to provide good drinking water in the villages, two students from Denmark have developed a water bag to purify drinking water by solar energy.

The water purification plastic water bottle named 'SolarSack' is inexpensive and environmentally friendly water purification object which uses the solar energy. The concept has already been tested in villages, refugee camps, and slums in East Africa where it will be marketed.

The two Danish architecture and design students, Anders Løcke and Louise Ullmann developed the plastic water container which holds up to four liters of water that can be purified from dirt and bacteria by sun exposure before the water is used.

In the direct heat of the sun for about four hours, between 99.9 and 99.999 percent of all harmful bacteria in the ‘Solar Sack,’ are eliminated. These results were confirmed during SolarSack testing in Kenya and Uganda, where local humanitarian organizations participated alongside with the Danish students.

The water bag which has been approved by the World Health Organization is less than a dollar and can be reused about 150 times. Thus, the water bag provides purified water with the solar energy without a cost.
