The Department of Wastewater Process Engineering focuses on research and development activities in the following areas:

• Industrial water cycle closure up to the wastewater-free factory ("Zero-Liquid-Discharge")
  • (Electro-) chemical oxidation processes
  • Process combinations
• Recovery of valuable materials from wastewater 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
• Generation of usable energy (electricity, heat) from chemically bound energy from wastewater and waste streams,
  • Bio-electrochemical power generation
  • Biological methane production from sewage sludge and waste
  • Process intensification and dynamic flexibilization
• Energy sources/products/chemicals from renewable raw materials.
  • Methane/hydrogen from renewable raw materials (sugar beet, maize, grass, algae)
  • Flocculants from potato and pea starch
  • Production of biomass (algae) using solar/LED radiation
