This meets the standard limits for discharge 50 mg/L. Reactor A was operated at sludge age of 40 days with the MLSS averaging approximately at 5900 mg/L [20]. In Figure 3, prior to addition of 10% refinery wastewater, effluent COD averaged approximately at 25 mg/L with an average COD removal of approximately 88%.
