Water quality monitoring is an essential fundamental for industrial process, human health and environmental sustainability. This thesis presents the development of an automated water quality monitoring and separation system which is PLC controlled and utilizes Potential of Hydrogen (pH), and Total Dissolved Solvents (TDS) sensors to assess water quality and display real time values on a Human-Machine Interface (HMI). Based on the measured parameters (pH and TDS), the system provides indications on the HMI, guiding the user to manually select the appropriate drainage compartment. There is often a noticeable gap between the way industrial automation is taught in classrooms and the practical skills that engineers need in real-world applications.
