Oxygen – the foundation of your process

Oxygen measurement guarantees the right aeration and supports energy optimization

Bacteria need oxygen to remove the organic and nutrient load. Furthermore aeration is the most expensive process step due to the energy consumption of the blower. The basic process control in aeration starts with online oxygen measurement. The oxygen feed can be controlled by comparison of the measured oxygen concentration and oxygen set-point.

Increase plant safety and energy efficiency

The typical requirements for oxygen measurement are reliable and accurate results, low maintenance, fast response time and no influence by air bubbles. Through our optical and amperometric sensors, you gain more flexibility for individual demands.

Preferred instrumentation

  • Liquiline transmitter with optical oxygen sensor COS61D

  • Alternative: amperometric oxygen sensor COS51D

Benefits of the measuring point

  • Very robust sensor design

  • Fast and reliable measurement

  • No electrolyte handling means less maintenance (optical sensor)

  • Memosens technology minimizes maintenance and allows for simple calibration

  • Easy handling and fast commissioning due to pre-calibrated Memosens sensor
