Diseño de un sistema automatizado de monitoreo y control de procesos hídricos en el Rancho El Manzanillo, Isla Santa Cruz.

Abstract

This study proposes the design of an automated water management and monitoring system based on a Siemens S7-1200 PLC and a SCADA system. The system, simulated in the TIA Portal, consists of two stages: pretreatment (with screens, a grit trap, and a filter) and treatment (with settlers, disinfection with chlorine, and UV light). Level, flow, conductivity, pH, turbidity, and radar sensors, along with actuators, allow for continuous control and real-time monitoring via a KTP700 HMI. Simulation results confirm that this design will achieve efficient, safe, and controllable management, with a projected 50% reduction in water consumption and operating costs, equivalent to annual savings of USD$4,400. This will facilitate wastewater reuse, comply with the Galapagos Islands' environmental protection policy, and contribute to environmental sustainability.
