Implementación de un sistema de control en el proceso de purificación de agua embotellada mediante un PLC

Abstract

This project aims to implement a control and monitoring system in the bottled water purification process using a PLC (Programmable Logic Controller). The system automates various stages of the process, including monitoring the quality of filtered water using a TDS (Total Dissolved Solids) sensor in PPM (Parts Per Million) through MODBUS communication between the PLC and an Arduino UNO, and PID control of levels in the filtered water tank. The implementation of this purification process begins with a detailed analysis of system requirements and the design of its architecture, followed by the selection of necessary components. Subsequently, PLC programming is carried out using TIA PORTAL software, defining control and monitoring functions for each stage of the process and conducting integration tests. Once programming is complete, the system is installed in the purification plant, followed by commissioning and personnel training. This approach ensures an efficient and reliable system for bottled water purification. Finally, an HMI (Human-Machine Interface) KPT700 will be set up with all defined variables to ensure optimal system performance over time. This HMI will receive alerts if the TDS sensor at the outlet of the filtered water tank detects a value in PPM outside the permitted range for human consumption, triggering alerts for
