Resumen

A pesar de que Ecuador es un país con una de las mayores concentraciones de ríos por kilómetro cuadrado, sus recursos hídricos son de mala calidad d hay una falta de sistemas de agua potable y alcantarillado para su población. En 2013, solo el 34% de la población rural tenía acceso a agua potable y el 25% a servicios de alcantarillado. Esto se debe a la falta de infraestructuras y de los presupuestos necesarios asignados a las mismas. El presente trabajo aborda una propuesta de potabilización de agua que consiste en el uso de la planta Moringa olifeira para facilitar el proceso de floculación, considerando que su uso reduce los costos asociados al tratamiento del agua y minimiza la concentración de metales en los lodos residuales. Los efectos de la dosificación de las semillas de la planta durante los procesos de floculación fueron explorados con pruebas de tarro utilizando una solución en dosis de 250 a 350 mg por litro de agua y evaluando luego la Demanda Química de Oxígeno (DQO) y la turbidez como variables de respuesta seleccionadas. La reducción de la DQO va del 45% al 55% mientras que la reducción de la turbidez va del 77% al 81%, haciendo posible y factible el uso de la planta.
