Aeration for wastewater treatment
Advanced monitoring solutions help optimize aeration in wastewater treatment and further save energy costs
Aeration in wastewater treatment accounts for approximately 60% of the total energy consumption in wastewater treatment plants. Energy consumption is the main cost driver in wastewater treatment, and its optimization is one if the many challenges faced by plant operators also having to meet ever more demanding safety legislation. Our online oxygen and nutrient measurement solutions not only drive energy savings in aeration control, they enable demonstrable improvements in biological processes.
Key facts

of the energy costs
in a wastewater treatment plant can be saved by using our solution for aeration control.
Process overview
Discover the aeration process in wastewater treatment
Insights
Simplified aeration monitoring
Reliable aeration requires the accurate monitoring of the multiple environmental parameters necessary for optimal bacteriological processes, such as oxygen, ammonium, nitrate, pH, temperature and suspended solids. Such monitoring increases greatly the complexity of management of the modern wastewater treatment plant.
Our expertise in the field
Our extensive portfolio of instruments, services and solution help to optimize the aeration process, enabling reliable and efficient plant management.

- Manage up to 8 measuring points of similar or different parameters with our multichannel transmitter Liquiline CM448. Open communication interfaces sustain system integration, smooth operations and effortless maintenance and calibration
- Safely remove nitrogen from wastewater with Liquiline Control
Insights
Reduced ammonium levels
The first step in nitrogen removal is nitrification. This requires close monitoring of the degradation of ammonium and represents a significant cost factor, as this type of liquid analysis often requires the addition of further substances to enable measurements.
Our expertise in the field
Our reliable, easy to use and durable technologies for measuring ammonium concentration throughout nitrification enable the operator to react early to ammonium level disturbances.
- Integration of reliable sensors such as our digital ammonium and nitrate Memosens sensor ISEmax CAS40D to optimize the treatment process
- Rely on high-precision ammonium measurement in all critical control points using Liquiline System CA80AM
- Further optimized life cycle costs due to lower maintenance and fewer consumables in treatment processes
Insights
Flexible, accurate oxygen control
Monitoring and sustaining the oxygen levels vital for a reliable aeration process can lead to significant energy costs for the wastewater treatment plant. Plant operators rely on fast response times and low maintenance of equipment.
Our expertise in the field
Oxygen levels are controlled by comparing the measured concentration and the set-point. Our oxygen monitoring solutions can be flexibly adapted to your requirements, delivering reliable and accurate results rapidly.
