Replacement of the two existing turbo compressors with two new Aerzen rotary lobe compressors of series Delta Hybrid, led to an additional energy saving of approximately 13 % of process air generation. Since then, the entire ...

  • Everything Depends on Pressure And Maintenance

    Energy and cost efficiency of biological treatment plants Every biologically working sewage plant needs a compressed air station for the oxygen supply of the aeration basin. This station only works at the highest possible energy efficiency level if excessive plant pressure through the subordinated system, excessive intake temperatures due to insufficient aeration and deaeration, and ...
