Abstract

The production of clean biodiesel from vegetable oil generates a large quantity of toxic wastewater. Most researches have been focused on the technical process of biodiesel production but the environmental management of the wastewater generated from the production process has not been given adequate attention. In this study, treatment of wastewater from biodiesel production by coagulation activities of defatted Moringa oleifera seed (DMOS) and inorganic coagulant, Aluminium sulphate (AlSP) was examined. Proximate analysis was carried out on the DMOS powder; and it was also characterized by Fourier Transform Infra-Red (FTIR) analysis. The coagulation process was carried out within 48 hours in jar test apparatus using 0.1%, 0.2%, 0.3%, 0.4% and 0.5% (w/v) of DMOS and AlSP respectively. The results show that 84.54% and 85.65% turbidity reduction occurred at coagulant dosage of 0.2% within 12 hours by DMOS and AlSP respectively. The FTIR analysis of DMOS showed functional groups such as O-H, C-O, and N-H indicating the presence of carbohydrates, esters and proteins respectively. It was suggested that the presence of a cationic protein of high molecular weight destabilizes the dissolved particles in the wastewater, and by a process of neutralization and adsorption, the flocculation and sedimentation activities occurred. Hence, it can be indicated that DMOS powder can effectively be used in place of inorganic coagulant to remove turbidity in biodiesel wastewater.
