Wastewater flows, sedimentation and oxygen transfer

In order to optimize the flow of waste water and the aeration tanks in the
sewage works, computational fluid dynamics can provide significant support
and potential for optimization. Thus we are able to support you in reassessing
your plant and finding potential for improving your project.
Principally, an increased efficiency of individual process steps can be shown.

  • Compactor, mixer and ventilation pumps
  • Nitrate/ammonium, phosphates and CSB
  • Enhanced utilization of oxygen, variation in the ventilation

or even of the layout of mixers and oxygen injection systems
The picture shows the ASM1 mechanism which is integrated in the CFD model.
For example, this can be used to realise the computation of nitrate decomposition.
The figures show a cross section of an aeration tank in a sewage works.
After a review of the actual situation we will draw up suggestions of where to
optimize.

Settlement characteristics of sludge. The evenly distributed sludge is divided into a clear water zone at the top and a concentration zone at the bottom. During the course of time, the sludge will thicken in the bottom zone.
