Modeling and optimizations of mixing and aeration processes in bioreactors with activated sludge

Abstract Mixing aimed at homogenization of the volume bioreactors with activated sludge is great importance for proper course wastewater treatment process. It affects both efficiency pollutants removal and properties related to its sedimentation. The mixing process in can be carried out different ways. In batch aeration phase or flow aerobic chambers, through systems. These systems should aerate flocs efficient biological treating wastewater, as well effectively homogenize bioreactor. Hence, it important choose such a design system operation settings that provide amount air ensuring exact oxygen implementation technological processes, counteract sedimentation bottom reactor, are reliable economical (demand electric energy). paper presents model studies optimization used active bioreactors.
