The HYDRA Nitrate Analyzer System from Electro-Chemical Devices (ECD) is ideal for nitrate monitoring in wastewater treatment aeration basins. Denitrification reduces the nitrate ion (NO3-) to nitrogen gas (N2) by an anoxic reaction in the same treatment basin or in a separate anaerobic digester. The nitrate as nitrogen (NO3-N) measurement helps optimize the methanol being fed to the digester and provide a trend indication of the total nitrogen in the effluent. The system measures the concentration of dissolved NO3-N in water by using a nitrate ion electrode and a chloride ion electrode.
