Technological progress in the agro-industrial field increases the amount of wastewater that, without being treated, pollutes the environment. Thus, the objective of the study was to evaluate the effect of moringa seed cake (Moringa oleifera Lam.) in the clarification of residual water, from the production of passion fruit nectar, using the jar test method, with concentrations of moringa cake of 5, 12.5 and 20 g/l, with stirring times of 10, 35 and 60 minutes for the extraction of the crude extract; and, doses of crude extract of moringa cake of 125, 175 and 225 mg/l. The greatest removal of turbidity from the residual water was obtained with 20 g/l of crude extract of moringa cake, with stirring times for the extraction of the crude extract of 35 and 60 minutes. Likewise, the dose of 125 mg/l presented the greatest reduction in turbidity by 82%. The results obtained in the research demonstrate that “moringa” cake is useful for treating wastewater produced in the production of passion fruit nectar, minimizing the turbidity of wastewater, resulting in a reduction in the environmental impact of effluents.
