Abstract
This paper presents a comparative experimental study of different configurations of mechanical surface aerators used in wastewater treatment plants. A laboratory scale tank equipped with different configurations for aeration process was installed to compare the standard aeration efficiency and power consumption of curved blade impellers with 3, 6, 9, and 12 blades. Different parameters thought to have significant effects on standard aeration efficiency (SAE) and power con�sumption, such as submergence depth and rotating speed were studied. Results show that an opti�mum configuration (9 blades) has the highest aeration efficiency (2.60 Kg. O2/KW.hr) at 500 rpm. Also, a submersion depth ratio of 0.35 was optimum, giving the highest standard aeration effi�ciency, as increasing submergence depth ratio above this value causes drop in standard aeration effi�ciency as a result of inevitable increase in input power consumption in this case.
