Kinetic evaluation of petroleum refinery wastewater biodegradation in an activated sludge process

Experimental assessment of process kinetic is essential for modelling and can serve as a useful tool to improve performance. In this study, evaluation petroleum refinery wastewater (PRWW) biodegradation in an activated sludge (ASP) was carried out 25 L ASP reactor which operated within the conventional aeration mode 2-10 hours, hydraulic retention time (HRT), effluents from secondary sedimentation tank were analyzed at various HRT biochemical oxygen demand (BOD) biomass growth. The data obtained fitted different related models show that PRWW follows Modified Monod Kinetic Model, amongst evaluated, with 0.9745 correlations experimental data. Physicochemical characterization used study using Standard Methods Examination Water Wastewater; gave biodegradability index 0.3333.
