The refinery wastewater (RWW) is very complex in nature, which need energy intense treatment. Thus, it is difficult for developing countries to manage the treatment of RWW. The feasible option to tackle the problem is co-treatment with municipal wastewater (MWW). In the present study, co-treatment of RWW (0, 10, 20, 40, 60 and 80) % with MWW was investigated in a bench scale extended aeration activated sludge (EAAS) reactor. The result indicate that the maximum organic removal was achieved at 20% RWW, which was 91.84%. However, first order substrate removal model and Stover-Kincannon model achieve the coefficient of correlation value of 99.17% and 99.14% respectively, which clearly indicate that these models can be implemented to predict the performance of reactor. Furthermore, designing of the EAAS treatment plant can be conducted for co-treatment of RWW with MWW.
