Abstract
Este proyecto presenta el diseño instrumental de un sistema de dosificación automática de hipoclorito de sodio al 16 % en la Planta de Tratamiento de Aguas Servidas (PTAS) Talagante, operada por Aguas Andinas S.A. El trabajo fue desarrollado como parte de la migración del sistema de desinfección basado en gas cloro hacia una solución más segura, eficiente y alineada con los estándares actuales de seguridad industrial y medioambiental. El diseño contempló cinco sistemas principales: carga, almacenamiento, trasvasije, dosificación y lavado automático del insumo químico. Cada sistema fue equipado con instrumentación específica, incluyendo transmisores de nivel, interruptores de nivel, sensores de derrame, caudalímetros, analizadores de cloro residual, bombas dosificadoras y válvulas electroactuadas. Todos estos elementos fueron integrados mediante un sistema de control compuesto por un PLC Allen-Bradley ControlLogix y una HMI PanelView, conectados a la red Ethernet de planta. El proyecto fue ejecutado exitosamente y el sistema se encuentra en operación, cumpliendo con los objetivos de seguridad, eficiencia operativa y trazabilidad. Esta implementación representa un avance en la modernización de los procesos de desinfección, contribuyendo a una operación más confiable, automatizada y sustentable.
This project presents the instrumental design of an automatic dosing system using 16% sodium hypochlorite at the Talagante Wastewater Treatment Plant (PTAS), operated by Aguas Andinas S.A. The work was developed as part of the migration from a chlorine gas-based disinfection system to a safer, more efficient solution aligned with current industrial safety and environmental standards. The design included five main systems: chemical loading, storage, transfer, dosing, and automatic skid washing. Each system was equipped with specific instrumentation, such as level transmitters, level switches, spill sensors, flow meters, residual chlorine analyzers, dosing pumps, and electro-actuated valves. These components were integrated through a centralized control system using an Allen-Bradley ControlLogix PLC and a PanelView HMI, connected to the plant’s Ethernet network via a Stratix 5700 switch. The project was successfully executed and the system is currently in operation, meeting objectives related to safety, operational efficiency, and process traceability. This implementation marks a significant step forward in the modernization of disinfection processes in sanitary facilities, contributing to a more reliable, automated, and sustainable operation.
