Abstract EN
Experimental analysis for a fabricated Low-Speed surface aerator that can be used in wastewater and water treatment is presented in this research.
The designed impeller configuration was tested to determine its power consumption, standard oxygen transfer rate (SOTR), and standard aeration efficiency (SAE).
Impeller oxygen transfer and power consumption in a scaled laboratory tank were measured during aeration phase.
The impeller was consisting of 8 inclines flat blades with an angle of 45° from center of the disc, was operated at 3 different immersion depths and 5 different rotational speeds for examining the impact of such factors on impeller efficiency.
The results recorded that the best standard aeration efficiency for this configuration is (0.206 Kg.
O2/KW.

submersion depth to impeller diameter (h/D) ratio equals 0.175.
Submergence depth increase beyond this limit would result in SAE decrease and definitely result into more power Experimental analysis for a fabricated Low-Speed surface aerator that can be used in wastewater and water treatment is presented in this research.
