Wastewater Process Engineering

Alignment

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")

  1. (Electro-) chemical oxidation processes
  2. Process combinations

II. recovery of valuable substances from waste water and its treatment residues (nutrients especially phosphorus, metals)

  1. Precipitation, flocculation, stripping, bio-electrochemical precipitation, bio-adsorption
  2. 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,

  1. Bio-electrochemical power generation
  2. Biological methane generation from sewage sludge and waste
  3. Process intensification and dynamic flexibilisation

IV. energy sources/products/chemicals from renewable resources.

  1. Methane/hydrogen from renewable resources (sugar beet, maize, grass, algae)
  2. Flocculants from potato and pea starch
  3. Production of biomass (algae) by means of solar/LED radiation
