In Fig. 3,symbols showed the experimental data for BTEX, while the 3-D mesh represents the predicted values from the model. Significant variations in the EC and removal rate in various phases were observed because of changes in the influent concentrations.
In the set II, all the experimental values were very close to the 3-D mesh values up to loading rate reaches 13 g m3 h1. Fig. 3(a–d) clearly showed that loading rate was further increased beyond 13 g m3 - h1, the experimental values deviates from the 3-D mesh values for BTEX compounds
