The Design expert version 6.0.8 was used for response surface methodology analysis.The correlation coefficients of determination (R2)for the developed models show that the actual data fitted well with the predicted data calculated from the models. The results indicate that at optimum conditions of 1.28g/50ml of Blend 3 dose, 20mins contact time and pH of 10.35, that 97.9908% nickel and 94.234% lead could be achieved. The petroleum wastewater treated at these conditions was compared to the raw sample and it showed a marked decrease in the concentration of the specified metals far below the standard limits set by NESREA and FEPA.
