biostudies-literatureUnknown8(9)Varsani VThe development of bio-coagulants from <i>Moringa oleifera</i> seeds for sewage wastewater treatment has been investigated. The prepared bio-coagulant was treated with distilled water, HCl, NaOH, and NaCl to surface-functionalize the <i>M. oleifera</i> seed powder (MOSP). The bio-coagulant performance was investigated by monitoring the reduction of turbidity, EC, pH, TS, BOD, and COD from the wastewater. SEM, EDAX, and FTIR characterized the native and functionalized MOSP bio-coagulants. The HCl treated MOSP was found to be effective and have good coagulation activity (∼90%) compared to natural and other MOSPs. The turbidity removal by all the MOPS conformed to the WHO acceptable limit of finished water. Hence, maximum turbidity reduction was recorded in HCl > NaCl > NaOH > Natural (distilHeliyone10447https://www.ebi.ac.uk/biostudies/studies/S-EPMC9468400biostudies-literatureDevelopment of bio-based material from the <i>Moringa oleifera</i> and its bio-coagulation kinetic modeling-A sustainable approach to treat the wastewater.PMC9468400Dudhagara DRVarsani VVyas SJfalseDevelopment of bio-based material from the <i>Moringa oleifera</i> and its bio-coagulation kinetic modeling-A sustainable approach to treat the wastewater.The development of bio-coagulants from <i>Moringa oleifera</i> seeds for sewage wastewater treatment has been investigated.
