Monitor remoto para sistemas de tratamento de água por osmose reversa

Abstract

The critical need for pure water is highlighted by the growing global demand for various purposes, especially in the pharmaceutical and hospital industries. Water quality, determined by standards and affected by pollution from natural sources, is becoming increasingly crucial. To ensure compliance with regulatory standards, treatment methods such as Reverse Osmosis are adopted. This study addresses the development of a remote monitor for Reverse Osmosis water treatment systems, with the aim of optimizing performance and operational efficiency in hemodialysis environments. Initially, the research explored the theoretical foundations of Reverse Osmosis and the use of filtered water in the hemodialysis procedure, as well as the need for continuous monitoring to ensure the quality of purified water, in addition to elaborating on the importance of this monitoring for promoting the concept of predictive maintenance. The project involved strategic collaboration with the company Vexer, a leader in the sector, for the prototyping and practical validation of the monitor in the real environment of a hemodialysis clinic. The prototype developed integrates a printed circuit board (PCB) specifically designed to connect with sensors and essential electronic components capable of evaluating the process. The monitor was housed in a rugged panel, suitable for industrial and hospital service environments, ensuring durability and organization, which also supported the power supply system, selected based on electrical calculations to ensure continuous operation. The operation and connectivity of the monitor was implemented through an operational program on the Espressif ESP32 microcontroller, using C++ language, and a cloud interface based on AWS (Amazon Web Services) to view data on dashboards accessible via web browser. This approach allowed continuous monitoring and automated alerts in cases of failures or irregularities in the Reverse Osmosis system, facilitating fast and effective interventions. After the prototype was developed, installed and operated for 90 days continuously in a hemodialysis clinic, representing the real use scenario, the monitor demonstrated effectiveness in early detection of problems, sending alerts by e-mail and storing historical data in the cloud for later analysis. KPI analysis through dashboards also provided a detailed view of operational performance, simplifying management and enabling the application of predictive maintenance concepts to the system. The successful implementation of the remote monitor, in addition to validating previous theories, culminated in Vexer’s decision to market the product under the name OsmoTrack. This initiative not only strengthened the credibility of the prototype developed, but also highlighted its commercial viability as an advanced solution for monitoring Reverse Osmosis systems, regardless of make, model or year.
