Applications
The ISEmax CAS40D is ideal for continuous monitoring directly in wastewater basins. This technology enhances process efficiency while lowering energy consumption in aeration systems. Its reagent-free operation provides additional cost savings. Featuring durable ion-selective membranes and effective self-cleaning capabilities, it minimizes maintenance requirements. The Memosens technology ensures superior process reliability, data accuracy, and user-friendly operation while enabling predictive maintenance.
The ISEmax CAS40D monitors ammonium, nitrate, and pH levels in municipal wastewater treatment facilities:
-
Aeration Tanks
– Continuous ammonium and nitrate monitoring
– Regulation of ammonium removal processes
– Load-based aeration control for process optimization -
Aeration Tank Inlets
– pH-compensated ammonium load measurement
