Due to the decrease of specific wastewater production, centrally managed wastewater systems are more and more prone to odour and corrosion problems. Particularly in anaerobic flow stretches, hydrogen sulphide is produced, which, in consequence to turbulences, escapes and leads to odour nuisance in the surrounding areas and, in the long term, to corrosion of the concrete components. The areas which are mainly affected are the transferring shafts in the rising main sewer.

The existing empirical approaches for the prediction of the mentioned phenomena feature considerable differences in the results and must therefore be used with caution. There are however, ongoing research activities aiming to develop new reliable methods for the prediction and control of odour and corrosion.

The study ODOCO-1 will cover the following tasks:

  • Definition of the state of knowledge about control systems to prevent odour and corrosion problems in sewer systems
  • State of the art of sensor technologies
  • Feasibility study to develop a 3 phases model to predict mass transfer of H2S from water to the gas phase and to the biofilm
  • Development of a first draft for a pilot-plant dedicated to the analysis of odour and corrosion phenomena.
