Energie-effiziente und dezentrale biologische Abwasserreinigung

Ref-Nr: TA-MBM-BioC-1754-HAWK


Kurzfassung

Die biologische Abwasserreinigung ermöglicht eine effiziente Eliminierung der Kohlenstoff-Anteile. Das heutige Problem besteht in der zunehmenden Nitratbelastung und der damit erhöhten Komplexität der Reinigung. HAWK-Wissenschaftler entwickelten eine energieeffiziente biologische Abwasserreinigung für den dezentralen Einsatz.


Hintergrund

In recent years biological wastewater treatment by fermentation has gained more and more interest. By utilizing anaerobic treatment biogas (energy) is produced as a by-product, which is a real benefit both economically and environmentally. For these reasons anaerobic wastewater treatment is installed in many industries, such as in the paper, milk and breweries.

Problemstellung

Nowadays, biological wastewater treatment can efficiently remove carbon sources. The challenge lies in the purification and elimination of nitrogen sources. Currently, a step-wise purification process having many different consecutive steps with different reactors and ponds are in use. This step-wise and serial process is complex and needs a lot of space for the different treatment units. Thus, for an on-side and decentralized biological wastewater treatment a compact and efficient system is badly needed.


Lösung

Scientists at the HAWK University of Applied Sciences and Arts, department of resource management, developed a compact on-side and and energy-efficient biological purification system for a decentralized wastewater treatment.


Vorteile

  • Flexible and compact system – only two units for three purification steps.
  • High purification efficiency by removing carbon as well as nitrogen sources.
  • Innovative combination of anaerobic and aerobic treatments.
  • Decentralized and energy-efficient biological wastewater treatment.
  • Energy-optimized process with passive aeration and production of biogas as valuable by-product.
  • Production of biogas for a sustainable on-side waste water purification.

Anwendungsbereiche

Compact biological wastewater treatment particularly for decentralized on-side use in e.g. beverage or farming industry.
