Abstract

Response Surface Methodology (RSM) is a powerful Statistical instrument utilized to explore the optimum levels of contribution factor(s), while the response is influenced by input factors. First major contribution in Response Surface Methodology was made by Box and Wilson (1951) and Box and Hunter (1957) originated from British chemical Industry. In the present study, the effect of two factors, hydraulic retention time and number of discs were tested on the removal of Biological Oxygen Demand through Rotating Biological Contactor. The Response Surface Model revealed that both, the retention time and number of discs have highly significant effect on the removal of BOD as; corresponding p-values are less than 0.01. Consequently the results obtained from Analysis of Variance are very much consistent with that of Response Surface Methodology. The optimum level of BOD with respect to removal was 78.99767. Furthermore, Response Surface Model was also elaborated to show the effect of retention time and number of discs on the removal of BOD.
