In this paper, we describe measurement and control practices in Finnish wastewater networks. We have surveyed the 14 largest wastewater treatment plants in the country, which account for approximately 40% of total Finnish treatment capacity. It was found that these plants still only rely on a few, traditional measurement techniques. The treatment processes could be improved, and the treatment could be made more energy-efficient by installing modern instrumentation. We review some recent developments in wastewater plant instrumentation technology and suggest improvements to Finnish plants. |
