Control Technology is getting more important in all areas, because its use can help to reduce the consumption of energy and resources. In an effort to make the operation of water or wastewater treatment plants more efficient, individual steps must be planned and sequences must be understood and double checked. Changing and maintaining fill levels are common daily tasks. These processes usually take place in the background or within areas of a machine or system that is not immediately visible. Nevertheless, monitoring process quantities such as fill level, pressure and flow rate offers a great deal of potential. Economy, improved quality and more safety of personnel and machinery are only a few of the goals which can be achieved by consistent process monitoring. SCADA (Supervisory Control and Data Acquisition) systems are used for collecting the data. Yet still, the analysis is often performed manually. Water utilities are facing the challenge of extracting useful information from data.

In this course the learning and understanding happens by way of doing hands-on laboratory exercises on the EDS - Water Management System. Class size is limited to ensure everyone is able to participate in the learning process. Below are learning outcomes from the exercises included in this course.
Controlling the fill level using a two-step controller:
- differentiate between linear and non-linear system characteristics
- demonstrate linear and non-linear system characteristics using the EDS® – Water Management
- control the fill level with a two-step controller by using the FluidLab® Water Management software
- describe controller settings/characteristics using the EDS® – Water Management
- explain the impact of switching difference and disturbance variable.
Controlling the fill level using a continuous controller:
- control the fill level with a continuous controller by using the FluidLab® Water Management software
- describe the characteristics of different continuous controllers
- explain the characteristics in the control circuit
- describe the effects of integral time and system deviation
- explain the characteristics of reset time and system deviation
- explore the affect of control settings on energy consumption.
Flow control using a proportional-integral controller:
- control the flow with a PI controller by using the FluidLab® Water Management software
- describe controller settings, characteristics and the effect of the disturbance variable
- explore how control settings effect energy consumption.
Volumetric Flow Control:
- adjust the volumetric flow by using different settings in the FluidLab® Water Management software to control the proportional media
- find “good settings” for the drain control using FluidLab® Water Management software to operate the proportional media valve.
Controlling the oxygen concentration using a two-step controller and controlling the oxygen concentration using a continuous controller:
- evaluate the best control strategy for the aeration processes.
