Resumen

El mucílago y el polvo de quimbombó se evaluaron como biofloculante en el tratamiento del agua usando la prueba jar. Los conjuntos de agitación, los métodos de preparación de quimbombó y la cantidad de coagulante / biofloculante se evaluaron en la eliminación de la turbidez. Los resultados mostraron que las agitaciones establecidas de 150 rpm y luego de 40 rpm fueron más efectivas para reducir la turbidez. Los resultados mostraron que al usar 80 mg l-1 de coagulante se observó un 39% de eliminación de turbidez y la adición de mucílago y polvo de quimbombó fue de hasta 76% y 88%, respectivamente. Por lo tanto, todos los resultados mostraron que el polvo de quimbombó presenta una mejor eliminación de la turbiedad en el tratamiento del agua. Puede prepararse por metodología simple y también permite la reducción del coagulante en aproximadamente 64%. En polvo de quimbombó se identificaron grupos hidroxilo que sirven como sitios activos para la eliminación de partículas coloidales.
