Development of a NO<inf>3</inf><sup>-</sup>-N analyser for real-time nitrate control in a pilot Urban wastewater treatment plant

Abstract:

This paper reports on the design and construction of a prototype for the measurement of Nitrate-Nitrogen (NO<inf>3</inf><sup>-</sup> -N) concentration in urban wastewater for real-time nitrate control in treatment plants. The system acquires the sample in an automatic mode and performs the measurement using an ion selective electrode (ISE). Additionaly the equipment has a friendly user interface and can exchange data with a supervisory system, using the MODBUS protocol over a RS-485 interface. Copyright © 2005 IEEE.
