“…For instance, heavy metals such as lead, copper, mercury or chromium have been shown to inhibit, or completely prevent, the oxidation of organic waste by bacteria 21. The extent to which toxic substances affect BOD values is well documented 22–24. As, in practice, such substances are rarely monitored, it is often difficult to tell if a decrease in BOD values is only due to a decrease in the organic load.…”

Real-time monitoring of wastewater quality remains an unresolved problem to the wastewater treatment industry. In order to comply with increasingly stringent environmental regulations, plant operators as well as instrument manufacturers have expressed the need for new standards and improved comparability and reliability of existing techniques. A review of currently available methods for monitoring global organic parameters (BOD, COD, TOC) is given. The study reviews both existing standard techniques and new innovative technologies with the focus on the sensors' potential for on-line and real-time monitoring and control. Current developments of biosensors, optical sensors and sensor arrays as well as virtual sensors for the monitoring of wastewater organic load are presented and the interests and limitations of these techniques with respect to their application to the wastewater monitoring are discussed.
