Abstract

Prediction of the pollutant concentration field in oxidation ditches A.I. Stamou of CW Zografou- Athens, Greece ABSTRACT The paper reports on the application of a water quality model for the prediction of the concentration field of a soluble organic substrate in a typical oxidation ditch. Calculations show that the concentration field is not affected by the use of guiding walls. Concentration profiles in the inlet region are skewed due to the effect of inlet, being strongly affected by the initial dilution. Downstream of the inlet region concentration profiles tend to be uniform. Decreasing the average flow velocity or increasing the bacterial population results to lower concentration values. 1. INTRODUCTION Mathematical models are powerful tools for the design of was- tewater units and the assessment of their performance under a variety of conditions. Unfortunately, due to the relatively high degree of sophistication
