The purpose of this investigation was to evaluate the coagulant power of 5 natural combinations to clarify the water of a wetland. The clarification process was simulated with the jar test and a rapid agitation at 120 rpm was established for this test for 1 minute, slow agitation at 30 rpm for 20 minutes and sedimentation for 15 minutes. For the natural combinations, a ratio of 90-10, 80-20, 70-30, 60-40, and 50-50
yucca -seeds of Moringa oleifera was determined. After the process, the turbidity of the water was compared with a control sample. It was determined that the best results were obtained with treatment 2, 4 and 5 that removed the turbidity of the water from the wetland in 89.7%,93.0 and 93.4% and 93.4% respectively.
En esta investigación se evaluó el poder coagulante de cinco mezclas de almidón de yuca y semillas de Moringa oleífera, para clarificar el agua de un humedal. El proceso de clarificación se simulo con el test de jarras y se estableció para esta prueba una agitación rápida a 120 rpm durante 1 minuto, agitación lenta a 30 rpm durante 20 minutos y sedimentación durante 15 minutos. Para las cinco combinaciones naturales, se estableció una relación 90-10, 80-20, 70-30, 60-40 y 50-50 almidón de yuca-semillas de Moringa oleífera. Finalizado el proceso, se comparó con una muestra control la turbidez del agua. Finalizado el proceso, la turbidez del agua se comparó con una muestracontrol. Se determinó que los mejores resultados se obtuvieron con el tratamiento 2, 4 y 5 que removieron la turbidez del agua del humedal en 89.7%, 93.0 y 93.4% respectivamente.
