Size-dependent anaerobic digestion rates of flocculated activated sludge: Role of intrafloc mass transfer resistance

Article Abstract:

The structure of the floc was identified with fluorescence in situ hybridization and a confocal laser scanning microscope (CLSM) technique. Microsensors were applied to assess the response of oxygen concentration distribution inside the flocs that are subjected to sudden changes in ambient oxygen levels, in order to verify the mass transfer resistance induced by flocculation.
