Software Solutions for Simulation, Monitoring and Data Acquisition in Wastewater Treatment Plants

This work approaches the design of software tools for a Wastewater Treatment Plant (WWTP) located in Făcăi, Romania, where the Distributed Control System/ Supervisory Control and Data Acquisition (DCS/SCADA) solution consists in four specific levels. More precisely, the paper proposes software solutions for the emulation of the control system from the WWTP. Due to the complexity of a WWTP, the proposed solutions and tools are dedicated to two levels of DCS. The specific bioprocesses (e.g. the activated sludge process) are simulated and the results are compared with data provided by the data acquisition system. Also, a software solution for the monitoring of process data provided by various sensors is designed. The proposed software solutions will be useful in future research for the design of advanced control systems in the WWTP. The software models and tools are designed in Matlab/Simulink, but also in LabWindows CVI and other software environments.
