The results obtained in this study clearly show the ability of the wind aeration in providing sufficient oxygen for the micro-organisms to effectively stabilize the organic matter. Since the mechanism of oxygen transfer to the water body is likely to be the shear stress and turbulence created by wind at the air-water interface, and increase in wind velocity should be expected to result in higher rate of oxygen transfer.
