Wastewater Process Engineering
The (waste) water treatment is a cross-sectional topic. Raw material extraction/recycling, energy conversion as well as industrial production are hardly or not possible without water use. Clean water itself is a valuable resource, especially internationally.
Our activities focus on water/wastewater/waste treatment (industrial wastewater, process water, sewage sludge) with the aim of improving energy and resource efficiency as well as industrial productivity.
Our research and development topics are:
I. Industrial water cycle closure up to the wastewater-free factory ("Zero-Liquid-Discharge")
- (Electro-) chemical oxidation processes
- Process combinations
II. recovery of valuable substances from waste water and its treatment residues (nutrients especially phosphorus, metals)
- Precipitation, flocculation, stripping, bio-electrochemical precipitation, bio-adsorption
- Nitrogen and phosphorus from sewage sludge, liquid manure, process water
III. generation of usable energy (electricity, heat) from chemically bound energy of wastewater and waste streams,
- Bio-electrochemical power generation
- Biological methane generation from sewage sludge and waste
- Process intensification and dynamic flexibilisation
IV. energy sources/products/chemicals from renewable resources.
- Methane/hydrogen from renewable resources (sugar beet, maize, grass, algae)
- Flocculants from potato and pea starch
- Production of biomass (algae) by means of solar/LED radiation
