Biological treatment using dense microbial aggregates such as biofilms or granular sludge is advantageous due to high biomass concentrations per reactor volume. But the conversion of contaminants in these dense clusters is significantly affected by mass transport limitations.
On one hand mass transfer limitations reduces the overall efficiency of the process as conversion processes will be substrate limited inside the aggregates and not all organisms inside the aggregates will contribute to overall substrate degradation.
But on the other hand mass transport limitations also provide opportunities resulting in distinct microbial niches inside the aggregates allowing for processes needing different environmental conditions and different organisms to take place in one reactor.
This presentation will discuss mass transport in dense microbial aggregates and to what extent we can predict these processes using mathematical models.
