Aeration for wastewater treatment

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 extensive portfolio of instruments, services and solution help to optimize the aeration process, enabling reliable and efficient plant management.

• Discover our portfolio of liquid analysis sensor covering all important parameters
• Take a closer look on our thermometers and transmitters from temperature measurement
• 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

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 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

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.

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.

• Measure dissolved oxygen concentration accurate with our digital aperometric oxygen sensor COS51Eor digital optical oxygen sensor Oxymax COS61D
• Increase process safety with Memosens 2.0 digital technology sensors
• Reduced energy consumption by further optimizing the blower usage
