Development of ceramic material composite systems for integration in function-hybrid modules for filtration and oxidation of trace contaminated water

The state of the art in wastewater treatment is conventional water infrastructure systems in which wastewater is collected in an alluvial sewer system and treated in central wastewater treatment plants. In the process, mainly organic material is degraded and the nutrients phosphorus and nitrogen are removed. Other pollutants, especially trace substances of anthropogenic origin such as drug residues and pesticides, are not or only partially degraded by today's standard treatment processes.

Against this background, the specific objective of the MemPhOx project is to develop and test functionally hybrid, compact filtration-photocatalysis material composite systems that can be combined into stacks for the degradation of trace substances. For this purpose, ceramic microfiltration membranes - designed once as flat membranes and in a second design approach as tubular membranes - and complex, partly graded cellular ceramic foam structures are to be coated with photocatalytically highly effective titanium dioxide and compactly connected with energy-efficient, long-life, environmentally friendly UV-A LEDs. The systems, which are completely free of operating fluids, are designed to remove trace substances of anthropogenic origin with simultaneous sterile filtration and degradation of residual organic contamination from water at the "point of use" and "point of emission".
