AUTOMATION IN WASTEWATER TREATMENT PLANTS
Abstract:The trend in wastewater treatment is toward more diversified and complex processes. This also leads to the need for a consistent operation, where automation is becoming increasingly important. Application of automation in wastewater treatment operation has two primary functions: information acquisition and process control. For the former function, the level of automation is relatively high. Many, often thousands of variables, are today gathered on-line in the SCADA systems of treatment plants and more or less sophisticated data analyses are standard components of the treatment operation and quality monitoring. However, the latter function, process control, is less developed and often limited to a few unit process control loops. Traditional explanations why this is the case generally refer to issues like inadequate process knowledge, lack of sensors for crucial parameters and insufficient control authority of the process.
There are several indications that the situation is changing and that the treatment industry is experiencing a transition towards a higher level of automation for both information acquisition and process control. In this paper some examples of high level control and automation are presented.
