Moringa Oleifera Seed Extract in the Clarification of Surface Waters
Full Paper(PDF, 377KB)
Abstract:
Moringa oleifera is a plant whose seeds have protein or polypeptide with coagulant properties. The present study evaluated the effect of Moringa oleifera seed (MOS) extract as primary coagulant and its mixture with aluminum sulfate in the treating of superficial waters with turbidities between 72 and 118 NTU obtained from Náinari lagoon located in Northwestern México. An average of 88.9% turbidity removal was achieved when MOS extract was used as primary coagulant with a dosage of 250 mg/l. In combination with aluminum sulfate reached 96.5% of clarification, and moreover is obtained saving 66% of chemical coagulant. The MOS extract is a viable alternative to diminish the use of chemical coagulants in the clarification of surface waters.
