title: Trends in monitoring of waste water systems.
abstract: A review of the trends in monitoring of waste water systems is given - with the focus on the use of sensors for on-line real-time monitoring and control. The paper formed a basis for discussion at the workshop on Methodologies for Wastewater Quality Monitoring, Nimes, 29-30 October 1998, organised by the European Commission and Ecoles des Mines d'Alès. The basic structure of the typical organisation of monitoring and control based on sensors and the handling of the sensor data are discussed and the different types of sensors are classified according to the method used for their introduction into the structure. Existing and new sensor technologies are briefly described, and the possibilities of how standardisation of on-line in-situ sensors can encourage further developments and use of sensors are presented.
