The aim of this project is to develop and validate a novel water quality-monitoring instrument incorporating a pH sensor with a nitrate sensor. The new sensors will exhibit improved reliability and durability over existing instruments with the added advantage of incorporating two sensors into one modular instrument. This will allow for more flexible sensor use with reduced size and cost over conventional instrumentation. This project has been formulated in response to the needs of end users who have greater than ever demands for water and effluent monitoring in many industrial, agricultural and water supply applications. This is due to an increased awareness of the importance of water quality with respect to both the consumer and the environment. The sensors will be applicable across the water and waste water industries, together with agricultural effluent, groundwater and other discharge monitoring and more general industrial processing applications where there is an increasing need for improved efficiency of water quality monitoring to effect cost savings and improve quality. To date the project consortium has completed the determination of sensor requirements and parameters leading to the specification and testing protocol documents. Commercial solid state reference electrodes have been tested for suitability for this application, opto-chemical pH sensors have also been investigated and work has been completed on membranes for high operational stability. The development of the nitrate sensor has been completed and the results from testing are imminent. The development of electronics, signal processing and data logging techniques is on going.
