In the thesis we look into the development of the concept test water treatment device with main focus on the development of the control system and graphic interface for monitornig the key parameters. Based on the concept device, the assembly of the device is shown. The first part presents theoretical basis of water treatment, including issues with water extraction, water resources and water treatment processes, which is followed by a more detailed review of the used processes. The second part comprises the system analysis, representing detailed view of the electrical and mechanical functions of the included elements and a list of key signals. Further on, the development of control program is described, presenting the used control hardware and an insight into the logic behind the subprograms of the components. In the last part, the graphical interface and the system SCADA production are described. The automated test water treatment device is developed, which will serve as testing and development enviroment for the new configurations of water treatment systems.
