"Effect of organic loading on the performance of aerated submerged fixed-film 85 reactor (ASFFR) for crude oil-containing wastewater treatment"

An aerated submerged fixed-film (ASFF) bioreactor was developed to treat an artificial wastewater based on crude oil. Bee-Cell 2000 was used as support media having porosity of 87% and a specific surface area of 650 m2/m3. The system was able to achieve 83.14-97.05 percentage removal efficiencies of...

Summary:An aerated submerged fixed-film (ASFF) bioreactor was developed to treat an artificial wastewater based on crude oil. Bee-Cell 2000 was used as support media having porosity of 87% and a specific surface area of 650 m2/m3. The system was able to achieve 83.14-97.05 percentage removal efficiencies of soluble chemical oxygen demand (SCOD) In the organic loading rate range of 0.84 to 9.41 g SC0D/m2.day. Results showed that the effluent SCOD concentration ranged between 18.93 and 100.93 mg/L at organic loadings experienced. Therefore, an ASFF process showed that it was feasible to treat high oily wastewater in order to meet the discharge standards.
