El presente trabajo evalúa la eficiencia del uso de la Moringa oleífera (M.O) como coagulante en el tratamiento de aguas de alta turbidez y carga orgánica. Inicialmente los resultados demostraron que el coagulante a base de las semillas de M.O pre-tratada con cloruro de sodio (NaCl 1.0 N) y usando una dosis de 0.74 g/L, alcanza remociones de 87.3% y 88.8% para turbidez y sólidos suspendidos totales (SST), asimismo valores de 25.9% y 26.3% para DBO5 y DQO respectivamente. En una segunda etapa, el coagulante, sometido a extracción Soxhlet y dosis de 0.5 g/L, muestran máximas eficiencia de 97.8%, 89.99%, 51.4% y 35.3% en la remoción de turbidez, SST, DQO y DBO5. Las más altas eficiencias obtenidas fueron alcanzadas mediante la previa extracción de aceites, grasas y otros componentes de la semilla de M.O. Estudios relacionados al reaprovechamiento de sub-productos de la extracción deben ser realizados.

In this study, the removal efficiency of Moringa Oleifera (M.O) seed as coagulant in the treatment of highly loaded wastewater in terms of turbidity and organic matter was evaluated. Initially the results showed removals of 87.3% and 88.8% for turbidity and total suspended solids (TSS) and 25.9% and 26.3% for BOD5 and COD respectively, when the seeds of M.O were pre-treated with sodium chloride (NaCl 1.0 N) and used as coagulant at a dose of 0.74 g/L. In a second stage, the natural coagulants previously subjected to Soxhlet extraction were compared, the results showed maximum efficiency with 0.5 g/L of the seed of M.O, with values of 97.8%, 9.99%, 51.4% and 35.3% in the removal of turbidity, TSS, COD and BOD5, respectively. The highest efficiencies were achieved through the prior extraction of oils, fats and other components of the M.O seed. Studies related to the reuse of extraction by-products should be performed.
