HACH Company announces a sensor for wastewater treatment facilities to measure nitrate and monitor plant performance.
The Hach NO3D sc Nitrate sensor coupled with Hach CARTRICAL technology enables plants to monitor their nitrogen removal online.
Nitrate measurement can optimise the nutrient removal process of a wastewater treatment plant. The Hach NO3D sc uses an ion-selective electrode to detect nitrate ions in the aeration basin as nitrate nitrogen. Designed for immersion directly in the aeration basin, it eliminates the need for sample preparation.
Hach says the NO3D sc sensor installs quickly outdoors without a special housing and can easily be relocated to various locations. The influence of chloride is compensated by using an integrated chloride electrode. The Hach CARTRICAL cartridge calibrates each electrode individually and all three electrodes to each other. A temperature sensor is also included.
Hach says their sensors arrive pre-calibrated and have fewer maintenance requirements. Single membrane and electrolyte exchange are not necessary as they are integrated into a sensor cartridge. The CARTICAL sensor cartridge is the only replacement part, and should be replaced approximately twice a year.
