Cleaning water with light: A new generation of compact and efficient water treatment systems

Story by Katrin Schwarz

Industrial process and wastewater pose a major challenge when it comes to environmental protection. Fraunhofer researchers in Dresden have now succeeded in developing compact and energy-efficient systems that use photocatalytic oxidation to efficiently break down impurities. At the heart of these systems are foam ceramics with multifunctional coatings.
