Make your aeration control less complex

Running biological treatment as precisely as possible

The biological process is a core step in modern wastewater treatment. COD and nutrient removal are essential requirements to comply with current legislation demands. Furthermore, approximately 60% of the total energy demand in wastewater treatment plants is used for aeration. Many plants already demonstrate significant improvements of outlet limits and energy savings of up to 30% by using online oxygen and nutrient measurements for aeration control.

To achieve a reliable biological process, it is essential to guarantee the best environment for the bacteria. Important parameters are oxygen, pH and temperature, as well as suspended solids which indicate the bacteria concentration in the basin. Advanced monitoring of the bacteriological processes based on oxygen, ammonium and nitrate makes it possible to meet strict legal regulations and to optimize energy consumption at the same time.

A standardized solution for essential online measurements

There is one solution to reduce the complexity of all needed analysis measurement points in the aeration process: the Liquiline multichannel transmitter. It manages up to 8 measuring points of similar or different parameters. Easy commissioning, calibration, maintenance, and open communication interfaces support integration and operation.

The value for you

  • Reduced life cycle costs due to lower consumables costs

  • Significant process optimization related to process efficiency and energy consumption

  • Less maintenance and lower spare part inventories due to the Liquiline platform
