The 2017 amendment to the Sewage Sludge Ordinance makes it mandatory to recover the phosphorus present in sewage sludge. Local sewage sludge recycling is promising. In the joint project "DreiSATS", a process chain for decentralized phosphorus recycling from sewage sludge was developed and demonstrated for the "Central German Tri-Border Area of Saxony-Anhalt, Thuringia and Saxony" region. Fraunhofer IKTS is developing temperature- and chemical-resistant ceramic hot gas filter systems for process-integrated heavy metal separation. Fraunhofer IKTS is also working on methods for evaluating the resulting ashes in terms of toxicity and their nutrient properties.
Persistent organic pollutants, such as veterinary and human pharmaceuticals, pesticides and industrial chemicals, typically accumulate in aquatic environments. Conventional water treatment processes are hardly able to remove them completely and without residues. With this in mind, Fraunhofer IKTS, together with partners in the joint project "MemPhOx", developed functionally hybrid filtration-photocatalysis-material compound systems that can be combined into stacks. Ceramic microfiltration membranes in planar or tubular design, cellular ceramic structures coated with highly effective photocatalytic titanium dioxide and energy-efficient, durable and environmentally friendly UV LEDs to stimulate the catalytic reaction were combined to form stacks and integrated into continuously operated treatment plants.
Wastewater treatment plants introduce oxygen in the form of air into aeration tanks to enhance nitrification by microorganisms. Highly concentrated oxygen is required to remove trace substances from wastewater using ozonation. Until now, the production of high-purity oxygen has been expensive. Fraunhofer IKTS has developed an energy-efficient membrane separation process that can significantly reduce the cost of decentralized oxygen supply. Other O2 applications will also benefit from this.
Fraunhofer IKTS develops membranes ranging from small geometries on a laboratory scale to large-scale multi-channel tubular membranes with a length of up to 1.2 meters. An important step towards industrial application is the upscaling of membrane production to membrane geometries with a high active membrane area. Pilot production lines are therefore available for various prototypes. Microfiltration, ultrafiltration, nanofiltration and zeolite A membranes have already been realized in this way.
