ABSTRACT

In this study, Defattened Mucuna Seed Coagulant (DMSC) was prepared, characterized and flocculation performance of the biocoagulant in turbid water clarification was compared with conventional coagulants. DMSCs were prepared and characterized using proximate composition analysis and Fourier Transform Infrared (FTIR) spectrometry. Batch clarification experiment was conducted using jar test apparatus. From the proximate analysis, moisture content, ash content, crude fiber and protein content were found to be 9.6%, 4.0%, 4.06% and 28.8%, respectively. FTIR analysis of the samples showed the presence of intermolecular hydrogen bond with hydroxyl group (polymeric chain) and amide group. The maximum Turbidity Removal Percentage (TRP) for turbid water for DMSC is 96.3% and this compares well with chemical coagulants with TRP of 97.2%. Thus, it can be concluded that DMSC is effective for water clarification.
