The ISEmax CAS40D is the right technical choice for direct trend measurement in basins. It improves efficiency and reduces energy consumption in the aeration process. The sensor uses no reagents, saving even more money. The robust ion-selective membrane and excellent self-cleaning function reduce maintenance work. Based on Memosens technology, the CAS40D combines maximum process and data integrity with the best operating comfort and predictive maintenance.
Advantages
Direct measurement of nitrate and ammonium without sample pretreatment, saving costs
Optional potassium and chloride measurement, and cross-interference compensation for reliable measurement
Automatic flushing unit for low maintenance costs
Direct installation at the basin edge, no sample collector or sample transfer pump required
Sensor parameter storage for convenient operation
Areas of application
The ISEmax CAS40D can be used directly for ammonium, nitrate and pH measurement in municipal wastewater treatment plants:
Aeration basin
- Determination of ammonium and nitrate concentration
- Control and regulation of the ammonium decomposition process
- Load-dependent aeration control to optimize the treatment process
Aeration basin inlet
- Determination of ammonium load (pH compensation)
