Prototipo a escala de una planta de tratamiento de agua residual automatizada para zonas con difícil acceso a reservas de agua

Abstract

The work in this thesis develops a scaled prototype of an automated wastewater treatment plant, specifically designed for areas with difficult access to water reserves. The main objective is to optimize the water purification process through the implementation of automation technologies, which allow efficient and precise control of the critical parameters involved in the treatment of water. The prototype is based on the use of an Arduino board as the central control unit, which manages the reading and processing of data from various sensors. Ultrasonic sensors are used to measure the water levels in the treatment tanks, ensuring constant monitoring and preventing possible overflows or accidental emptying. In addition, a pH sensor is integrated to evaluate the acidity or alkalinity of the water, allowing automatic adjustments to the treatment process and maintaining water quality within optimal ranges. Automation of the system not only improves treatment and efficiency, but also partially reduces the need for constant human intervention, which is especially beneficial in rural or hard-to-reach communities. The results obtained demonstrate that the prototype is capable of autonomously managing the complete wastewater treatment cycle, thus contributing to sustainability and access to quality water resources in vulnerable environments.
