Nutrient measurement enables process optimization and outlet control in wastewater treatment plants. It also helps to monitor the water quality during water treatment.

In-Situ measuring systems These systems enable continuous measurement of nutrients directly in the medium. Using a suitable assembly, they are directly mounted in the process and deliver fast measured values. That‘s why they are especially suited to process control. Your benefits • Continuous, real-time measurement directly in the process • Digital Memosens technology for reliable, interference-free communication • No sample conditioning required • No reagents required • Compact systems, easy to install

Ammonium and nitrate measurement with the ion-selective measuring system ISEmax CAS40D/Liquiline CM44

ISEmax is used for the continuous measurement of ammonium and/ or nitrate in the aeration basin of municipal wastewater treatment plants. The sensor consists of ion selective electrodes that measure ammonium, nitrate and, where applicable, other measured variables simultaneously and a reference electrode. The sensor is installed in an immersion assembly with automatic compressed-air cleaning and a pre-amplifier. Using a suitable holder, the sensor is mounted directly on the basin rim. Your benefits • Ammonium and nitrate in a single sensor: you always have nitrification and denitrification under control • Low maintenance thanks to easy exchange of membrane caps • Robust membranes and the

in the sludge activation process • Rapid change of measured values for control and regulation • Determining the ammonium load (pH-compensated) in the inlet to the sludge activation process • Load-dependent aeration control Diverse measuring ranges • Ammonium-nitrogen: 0.1 to 1000 mg/l NH 4 -N • Nitrate-nitrogen: 0.1 to 1000 mg/l NO 3 -N

integrated cleaning system ensure that the sensor is always operational. Typical applications

• Measurement of the concentration of ammonium and nitrate directly
