Abstract
The present study aimed to assess the best concentration of Moringa oleifera Lam. and the best sedimentation time in order to remove turbidity from water extracted from the Capibaribe River, in the city of Recife, Pernambuco, Brazil. The proposed treatments consisted of zero, 50, 100, 200, 250 and 300mg of moringa dust / 200mL of water, with a exposure/sedimentation time of zero, 1, 2, 4 and 6 hours, adjusted by a CCD experimental plan. Before and after the application of each treatment, turbidity, pH and electric conductivity were measured. The obtained results were analyzed through an ANOVA table and a Pearson graphic with a significance level of 5% and correlation between variables. The essay results have shown a reduction of up to 100% of turbidity, at a 200mg concentration of moringa dust with the sedimentation time of 2 hours as well as a reduction of the other physicochemical parameters measured.
