Research output: Contribution to specialist publicationArticle


This paper describes the influence of mass transfer limitation on the overall oxygen consumption in biological waste water treatment with local aeration which is a common situation in all process industries including mineral processing industries seeking biological purification of effluents before discharge to the receiving water. The transfer of oxygen from gas to liquid is achieved by physical means in most aeration processes. The alternative methods of creating the necessary contact area are also considered. It also discusses about the suitability of U-tube aerators in producing any desired concentrations. Finally, a method is presented for measurement of oxygenation capacity and efficiency.
