Influence of Macromixing on Organic Carbon Uptake and Solids Production by Aerobic Suspended Biomass

Abstract

The influence of macromixing on organic carbon uptake by aerobic suspended biomass has been investigated using two reactors operated in parallel, i.e. a perfectly mixed reactor and a compartmented reactor. Conversion determined on filtrated samples is identical in both of the reactors but with less solids production in the low-dispersed reactor. The reaction rate established on the perfectly mixed reactor shows an apparent first-order with influence of inlet concentration but this relation cannot be used in a mass balance over the compartmented reactor.
