The objective of this research was to determine the dose of moringa cake extract (Moringa oleifera Lam) for the removal of turbidity from an effluent from a passion fruit nectar processing plant. Proximate analysis of moringa cake and extracts (crude and purified) was performed. The amount of crude protein in the cake and extracts were 50.214%, 4.630% and 50.130%, respectively. Polyacrylamide gel electrophoresis (PAGE-SDS) revealed a main polypeptide band whose molecular weight was approximately 6.5 kDa. For the evaluation of turbidity removal, a factorial experiment in Completely Randomized Design (DCA) was used, with the factors being: Factor A: effluents at different turbidity levels and factor B: dose of moringa extract. At levels of 250 to 450 NTU, with doses of 600 mg/L, with the crude extract, turbidity removal was achieved in the range of 46.88% to 51.51% and with the purified extract, with doses of 300 mg/L, Better turbidity removal was achieved, between 87% and 95.50%. Regarding the color with the same NTU levels, a variation was observed directly proportional to the changes in turbidity. With the dose of 600 mg/L of crude extract, the decrease in color was from 36.59% to 58.59% and with the purified extract, with a dose of 300 mg/L, a decrease in color from 85.37% to 91.92% was achieved. In the case of electrical conductivity, as well as for total dissolved solids (TDS), an increase from 2.45 to 3.55 mS/cm for electrical conductivity and from 1.52 to 2.61 mg/L for TDS was observed. Finally, the pH was not significantly affected, remaining in the range of 3.06 to 3.80.
