Determination of kinetic coefficients for treating synthetic oily wastewater in suspended growth batch fed reactor

Discharge of oily wastewater imparts serious threat to the environment because of high level concentration of chemical oxygen demand (COD), biochemical oxygen demand (BOD) as well as oil and grease and it is difficult to treat such wastewater due to its inherent toxic and inhibitory property. A trea...
