Assessing the Performance of Jatropha Curcas and Moringa oleifera Conditioners Towards Improving Fecal Sludge Treatment for Agricultural Purpose

Abstract

Moringa oleifera (MO) and Jatropha Curcas (JC) conditioners have been proposed as alternative solutions to replace chemical conditioners for fecal sludge (FS) treatment. However, their effectiveness in treating FS for safe agricultural use has not been thoroughly evaluated. The aim of this study was to assess the suitability of FS treated with Moringa oleifera and Jatropha Curcas conditioners for agricultural use. Physicochemical parameters Indexes, salinity and sodium hazard levels (Wilcox Diagram analysis), and removal efficiency of nutrients and pathogens were evaluated. Qualitative experiments were conducted using dewatering treatment chambers containing untreated control FS samples, FS treated with Moringa oleifera and Jatropha Curcas conditioners at the University of Dar es Salaam Water Laboratory.
