description | The Behavior of an extended aeration activated sludge process was studied. Factors that might affect the performance of such process were also investigated. Three basins, each consisted of two parts one for aeration and the other for sedimentation were employed. Required tests and results analysis were made. It was found that removal efficiency of dissolved organic matter was limited to F/M ratio. The study revealed that such treatment was capable of treating variable characteristics wastes. The supernatant leaving secondary sedimentation was found to attain constant characteristics irrespective of variable influent. The results show that the maximum overall COD removal efficiency occur at hydraulic detention time equal to 23 h, 80% of SVI value was less than 125 ml/gm and the minimum SVI occur at F/M equal to 0.387 day-1 while the effluent SS increase with SVI decrease.
