Electro-Chemical Devices HYDRA Nitrate Analyzer SystemIdeal for nitrate monitoring in wastewater treatment aeration basins, the new HYDRA Nitrate Analyzer System from Electro-Chemical Devices, Inc. (ECD) offers a precision nitrate ISE electrode sensor with an integral self-cleaning sprayer. The HYDRA Nitrate Analyzer System monitors the nitrification process in aeration basins at wastewater treatment plants, a process during which toxic ammonium ions are oxidized into much less toxic nitrate ions using an aerobic activated sludge process. De-nitri?cation 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 NO3-N measurement helps optimize the methanol being fed to the digester, minimizing cost and also to provide a trend indication of the total nitrogen (TN) in the effluent.
