| Abstract | This research covered an investigation of the effect of crude oil on the performance in terms of COD removal efficiency and effluent suspended solids concentration of the different biological treatment processes. Glucose synthetic waste was used as an influent substrate with organic loading of 0.4 kg COD/m3-day for the control unit. Two different oil loadings of 0.26 and 0.52 kgCOD/m3-day were studied. The extended aeration activated sludge, rotatory tube filter and lowrate plastic packed trickling filter were investigated in this study. The extended aeration activated sludge process was proved to be efficient in terms of COD removal of 93.6 and 90.1% at the oil loading rate of 0.26 and 0.52 kg COD/m3-day respectively. The low-rate trickling filter process was found to be the most efficient system in terms of COD removal and effluent suspended solids concentration. Adsorption of oil on the slime and following degradation by the microbial mass would be attributed to the higher treatment efficiency. The rotatory tube filter was not comparable to the low-rate trickling filter process in terms of COD removal. |
