Wastewater Treatment and Ammonia Concentration Sensing

Ammonia and Nitrate Sensing
Selection of the proper Ammonia
and Nitrate sensor
for clean water.
Ammonia is found naturally in water, but when found at higher than natural levels (even in very low concentrations) it is toxic to fish and other aquatic organisms. The controlled discharge of ammonia from wastewater treatment plants (WWTPs), large farms, and landfills is an important topic across the United States. Many states adopted new rules addressing total ammonia discharge. Selecting the proper sensor for accurate and repeatable ammonia and nitrate concentration is critical.

The HYDRA Ammonium Sensor is designed to monitor the nutrient load (NH4+) directly in the aeration basin of a Waste Water Treatment Plant. The HYDRA uses ISE technology to measure the ammonium, potassium and pH. Compensation for the pH dependent concentration equilibrium and potassium ion interference on the ammonium electrode are preformed automatically in the HYDRA C22 analyzer.
