BIOX-Capacity Increase of WWTP

Proper dosing of oxygen to manage the biology


With the injection of pure Oxygen, a significant increase in the efficiency of existing, overloaded sewage treatment plants is achieved quickly and economically. It ensures compliance to consent levels and makes cost-intensive extension of the activated sludge basins superfluous. Pure Oxygen may be used to replace the existing aeration as well as an additional asset. The performance of biological treatment steps is raised up to 200%. Therefore pure Oxygen is especially suitable for high-load basins, selector basins and moving bed reactors.


The advantages at a glance: 

  • Quick and easy performance increase of the activated sludge process
  • Reliable cutting of peak loads
  • Ensures proper DOC for Nitrification
  • Low investment costs
  • rapid implementation within 2 days
  • temporary measure for emergency aeration
  • Economical and flexible
