The three-phase flow in a aeration tank driven by an inverted umbrella aerator is relatively complex, including the processes of hydraulic jump, air entrainment, and sludge particle sedimentation. A test bench for established studying its influence on performance. experiment mainly studies changed law performance under different immersion depths or concentrations measures rate working condition...
Pilot plant study showed that there is a relationship between the HRT in aeration tank and the % removal of soluble COD in the final settler if DO is not a limiting function. It was found that the % removal of soluble COD in final settler increased from 13 at HRT in aeration tank of 12 hours to 45 at HRT of 4 hours. Mathematical model was also presented in order to predict the soluble COD utili...
X-ray examination of the chest revealed a large circumscribed area of absent aeration in the central portion of the left lung which extended from the axillary portion of the chest to the hilum, merging with the mediastinal structures. In the lateral projection, this circumscribed area was superimposed over the heart. An aneurysm could not be excluded; the area of diminished aeration was thought...
3. Lababidi Z, Dyke PC, Angiographic demonstration of spontaneous occlusion of systemic arterial supply in pulmonary sequestration. Pediatr Cardiol 2003; 24: 406-408. tion. Communication through the Pores of Kohn leading to partial aeration of the sequestration was responsible for the partial aeration seen after bronchoscopy. Srikanth, et al.(2) reviewed 57 cases and reported that bilateral com...
Introduction: Extended aeration activated sludge system has a lower sludge production than other activated sludge processes. Due to its high hydraulic retention time (HRT), the tolerance of this process is higher than the shocks caused by increased organic loading rate. The main objective of this study is to evaluate the performance of the aeration system in removing physicochemical and mi...
