Abstract

The objective aim of this research was to predict dissolved oxygen (DO) concentration in a full scale ACTIVATED SLUDGE reactor. So tested a function for oxygen transfer. The ACTIVATED SLUDGE model No.1 was used to describe the biochemical processes. The function of dissolved Oxygen was used by first- order differential equations. This model was simulated by MATLAB Software. The simulated model was tested for a laboratory pilot and shahrak Ghods treatment plant. The obtained results confirmed the data obtained from the model and the experimental one.Laboratory duplicates and field duplicates were done for two samples to give a measure of the precision associated with laboratory procedures and sample collection and preserving.The concentrations of MTBE in two samples of surface water were 11ppb and 6 ppb. The reason may be due to MTBE spills from repair shops or it is because of used motor oil which spills to the surface water.
