WebOct 29, 2024 · This structural heterogeneity is evident on even smaller, μm-scale, where variations of up to 74% in biofilm thickness could be identified ( Figure 4 ). Consistent to the control hose, thickness data was used to calculate the approximate average biofilm volume, which was 9.8 ± 4.6 × 10 8 μm 3 /cm 2 ( n = 200).
WebThe role of sorption and biodegradation in a membrane aerated biofilm reactor (MABR) were investigated for the removal of 10 organic micropollutants (OMPs) including endocrine disruptors and pharmaceutical active compounds. The influence of the biofilm thickness on the mechanisms of removal was analyzed via kinetic test at three different stages.
The 0.5 m3 MBBR was located at the Sjölunda WWTP in Malmö, Sweden.
