Abstract
Oil),were used with Design of Experiment(DOE)Method. In this Method, Response surface model(RSM) was
obtained in the view of a Box-Behnken design (BBD) with four variables as the input factors, i.e. TiO2 loading (g/l),
pH, oxidant amount (ppm) and aeration rate (l/min). The optimum quantity of every factor was calculated according
to the experimental settings and statistical model parameters. Finally, High COD removal in 90 min (93%) were
obtained under optimum conditions.
