The ammonium analyzer is a compact analyzer for online measurement of ammonium in relatively clean applications. In combination with our filter unit, see ????, this analyzer is also very suitable for wastewater applications.
Operation:
The analyzer is an online measuring system that batch-wise analyzes a sample of wastewater for the concentration of ammonium. The internal pump pumps a (waste) water sample to the measuring chamber at a set frequency (6 – 20 minutes). A fixed amount of reagents is added to this sample. The reagents will react with the ammonium present in the sample. This causes a color change in the liquid. After a fixed reaction time, the analyzer measures the color intensity. An LED light source and a photodiode are used for this. The color intensity is directly proportional to the concentration of ammonium. After each measurement, the measuring cell is rinsed with an acid to prevent interference.
