Title: | Thermodynamic study of the aeration kinetic in treatment of refinery waste water in bio-aeration tanks | Authors: | Ševaljević, Mirjana Stanojević, Miroslav Simić, Stojan Pavlović, Milan |
Issue Date: | 15-Nov-2009 | Journal: | Desalination | Abstract: | The intention of this article is the examination of effects of aeration regimes on the agreement between technical parameters measured in prior works, with calculations, in this article based on thermodynamic considerations. In the aeration tank with waste water, the technical characteristics of the air distributors based on volume transport coefficients of oxygen are dependent on variation of air flow and added motor oil contents. In this work, it was shown that the oxygen solubility degree compared to distilled water is controlled with the ratio between the periods of saturation of aerated water and oxygen relaxation over-pressure time. In longer saturation period, it was controlled by thermal gas oxygen distribution but in shorter saturation period, by mass-balanced dissolution in liquid. The rate constants for achieving partial local equilibrium (PLE) of oxygen could be identified based on agreement between experimentally obtained and calculated parameters of aeration kinetics. © 2009. | URI: | https://open.uns.ac.rs/handle/123456789/11640 | ISSN: | 00119164 | DOI: | 10.1016/j.desal.2008.11.009 |
