Photocatalytic water treatment


TiO2 nano-coated ceramic foam with integrated UV-source
Rhodamin suspension under UV for selection of powder

Several technologies for removal of micro-pollutants are currently being investigated for their general suitability and efficiency. A promising alternative to methods with high use of chemicals is the photocatalytical treatment under use of nanostructured materials. The mechanism bases on the formation and further reaction of radicals thus it belongs to the group of AOP (advanced oxidation processes). The working group biomass conversion and water technology develops powerful, compact, chemistry and biology-free water treatment systems using functionalized materials such as ceramic membranes and foams. To evaluate the photocatalytical activity of powders, granules and coated surfaces of various test stands in batch mode and continuous variation in relevant process parameters such as radiation intensity and active surface can be operated.
