Purpose and goal

The purpose is to develop a low-cost, safe solar water purifier for developing countries. A solar panel measuring only 20x30 cm in size and can deliver approximately 1.5 liters of clean drinking water per hour at full sunshine. That makes 9 liter every 6 hours. Enough to cover the daily need for a family of four people. We have a working prototype with which we have carried out several lab test using wather with high bacterial concentration. The level of bacteria was measured before and after using Instant water. The result showed a decrese of bacteria from 2000 units to only 3 units.

Expected effects and result

The aim was to develop a safe solar water purifier for developing countries at a very low cost. We have developed a working prototype with a unique control system wich ensures that only water that has achieved the right temperature can leave the water purifier. One unit measuring only 20x30 cm can provide about 1.5 liters of clean drinking water per hour at full sunshine.Tests have been carried out using wather with high bacterial concentration. The level of bacteria was measured before and after using Instant water. The result showed a decrese of bacteria from 2420 units to only 3 units.

Planned approach and implementation

The project´s goal was to investigate whether it is possible to clean water with solar energy safely at a very low cost. We have manufactured a smaller series of tests and tested the technology under real circumstances in Sweden. The results show that we can transform heavily polluted waste water into acceptable drinking water, solely with the energy of the sun.
