Resource and Energy management
- Sewage and waste as an energy source
- Anaerobic technology (co-digestion, biogas, hydrogen production)
River Basin Management
- Matter Transport and Reactions
Urban Water Management
- Matter transport, -retention and transformation in catchments
Adepted Technologies
This Working priorities become investigated by three Divisions: "Process Technology", "Water Quality Management" und "Semi- and Decentralised Systems".
Process Technology within Wastewater, Water and Solid Waste Treatment
- Nutrient Recovery ( Phosphorus: Crystallisation Technology, MAP Precipitation; Nitrogen: Ion Ex-change using Zeolites)
- Enhanced Wastewater Treatment (Precipitation, Flocculation, Phase Separation, Chemical Oxidation Processes)
- Application of Sophisticated Measurement Tools (Zeta Potential, Particle Size Distribution (PSD) and Settling Velocity)
- Concept Development for Industrial Wastewater and Leachate Treatment
- Characterisation of Organic Substrates for their Suitability as External Carbon Sources and their Gas Production Potential within Co-Digestion
- Quantification of the Co-digestibility of Solid and Liquid Organic Wastes
- Sewage Sludge Treatment, Conditioning and Valuable Matter Recycling
- Optimisation of Wastewater Chemical’s Application
- System Analysis, Supervision and Consulting of Plant Operators, Industry and Water Authorities
Left: Pre-treatment of biowaste for co-digestion (screens to separate floating and light density matter out of the pulper); Right: Zeolites of different proveniences and different particle sizes for the ammonia exchange process)
Biofilm Technology
- Rotating Biological Contactors (RBC) for Municipal and Industrial Wastewater Treatment
- Suspended Carrier Media (MBBR) to increase the Capacity of Activated Sludge Systems and to Unload the Secondary Clarifiers
- Biofilm Characterisation (Biofilm Thickness, Oxygen Profiles, Activity Tests)
- Simulation of Biofilm Systems
