Esta investigación evalúa la viabilidad de la electrocoagulación (EC) por energía solar como una tecnología de tratamiento pertinente, accesible y de bajo costo. Se diseñó un reactor discontinuo a escala de laboratorio para tratar agua sintética que simula las características fisicoquímicas y microbiológicas de un río de bosque seco tropical, con una turbidez inicial de 30 NTU, una DQO de 50 mg/L y una elevada carga de Escherichia coli (1×106 UFC/mL). Los resultados mostraron una alta eficacia, con una remoción de turbidez alrededor de 88,5%, una reducción de la DQO del 76,5% y una reducción logarítmica (LRV) > 6 para E. coli en 60 minutos. Se concluye que la electrocoagulación solar con electrodos de hierro es una alternativa robusta, económica y confiable para la potabilización de agua a pequeña escala, con un alto potencial de implementación en comunidades rurales. This study investigates the feasibility of solar-powered electrocoagulation (EC) as a suitable, accessible, and low-cost treatment technology. A lab-scale batch reactor was designed to treat synthetic water simulating the physicochemical and microbiological characteristics of a tropical dry forest river, with an initial turbidity of 30 NTU, a Chemical Oxygen Demand (COD) of 50 mg/L, and a high Escherichia coli load (1×10⁶ CFU/mL). The results showed high efficiency, with a turbidity removal of approximately 88.5%, a COD reduction of 76.5%, and a log reduction value (LRV) of >6 for E. coli within 60 minutes. It is concluded that solar electrocoagulation with iron electrodes is a robust, cost-effective, and reliable alternative for small-scale drinking water treatment, holding significant potential for implementation in rural communities.
