Diseño y simulación del proceso de tratamiento de aguas residuales usando PLC, HMI y pasarela inteligente IOT2040 de SIEMENS

Abstract

Wastewater treatment plants are essential for improving the quality of water resources returned to the environment after daily societal use. In recent years, the demand for this service has increased, and the reliance on technologies considered obsolete and limited today negatively impacts both quality and resource optimization. At the academic level, there is a lack of educational environments where sub-processes, variables, and outputs involved in plant control using Industry 4.0 technologies can be observed. This limits students’ preparation for specialization in a niche where they could contribute to continuous improvement with automation and engineering skills. This project aims to simulate the wastewater treatment process using SIEMENS PLC, HMI, and IOT2040 smart gateway through the TIA Portal and Node-RED software. The goal is to provide students with a more up-to-date framework featuring advanced monitoring and control technologies, thus addressing an existing issue. The methodology involves PLC programming, HMI interface design, and the implementation of an IoT dashboard for remote monitoring. This project is relevant as it will contribute to the development of skills and competencies to address the challenges currently faced by wastewater treatment plants, improving service delivery through IoT technologies and an innovative approach aligned with Industry 4.0.
