Controlling ammonium (NH4+) levels in water is crucial to protect the environment, human health, and wastewater treatment efficiency. High NH4+ can lead to eutrophication, toxic ammonia formation, and harm aquatic life. In drinking water, it contributes to nitrate contamination and chloramine formation, posing health risks. Wastewater plants must regulate NH4+ to optimize nitrification, prevent sludge issues, and comply with environmental regulations. Industries and agriculture also monitor ammonium to prevent corrosion, biofouling, and soil degradation. Effective control ensures clean water,...

Measurement principle UV FTLS SPECTROSCOPY IN GAS PHASE The gas phase measurement for NH4+ allows to avoid interferents such as turbidity, color, suspended solids or salinity, and to have a good accuracy of its concentration. BLANK TRANSMISSION SPECTRUM SAMPLE TRANSMISSION SPECTRUM MATHEMATICAL TREATMENT SAMPLE COLLECTION The sample is collected thanks to a tubing directly immersed in water or via a sampling system (not provided) if the analyzer cannot be positioned nearby. CONVERSION OF AMMONIUM (NH4+) INTO AMMONIA (NH3) The sample is injected into the sparger, and the addition of a reagent...
