Hydraulic engineer Andrea Schäfer and photovoltaics expert Bryce Richards have developed a solar filtration system to produce high-quality drinking water from polluted brackish water and tested it successfully in Tanzania. The test results are currently being analyzed at the KIT. The filter effectively separates undesired substances, bacteria, and viruses. Fluoride concentration that often is extremely high in Tanzania is reduced below the limit given by the World Health Organization (WHO). The system combines two membrane techniques for the separation of smallest particles and dissolved contaminants. As it is robust and autonomously mobile, it is suited well for water supply in poor and rural areas.
