An evaluation of the distribution of DO concentrations in aeration tanks at Lattakia WWTPs

This research includes monitoring the distribution of DO concentrations in the Marj Maarban and AL Ruyemih WWTPs which use different types of aeration systems (surface aerators and diffusers). Research has shown a remarkable increase in the values of DO concentrations in the studied aeration basins above 2 mg/l which means an increased electricity consumption and operational problems, in addition to the role of the natural aeration process in reducing the number of aerators operation hours. This will reflect positively on the performance of the plant and the investment cost.
