  • Sufficient air in the fixed bed reactor

    Delta Hybrid rotary lobe compressors made by AERZEN What about the typical sewage water smell? No chance! Visitors to the “station d’epuration” located in the district of Beggen have to pay close attention in order to realise that a wastewater treatment plant is in the neighbourhood - and one wich processes a daily water volume between 30,000 and 40,000 m3. In order ...

  • Turbo Blowers made by AERZEN for Base Load, Delta Hybrids for Peak Load - Step by Step Towards the Ideal Sewage Plant

    Thanks to the reduced sewage duty resulting from basic changes to the aeration basins in 2008, modification costs of € 1.3 million were amortised after only three years. 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 ...

  • Bespoke noise protection: AERZEN relies on the advantages of reactive silencers

    With reactive silencers, AERZEN reduces the noise emissions on the discharge side of its screw compressors, positive displacement blowers, and rotary lobe compressors. The innovative concept of these reactive silencers is superior to classic dissipative silencers in many respects. The sound waves developing on the discharge side of a Delta Screw compressor made by AERZEN can reach 170 to 190 dB. ...
