Abstract

The three-dimensional pore structures in waste activated sludge floc were identified using the fluorescence in situ hybridization (FISH) and confocal laser scanning microscope (CLSM) images. The meshes of the three-dimensional porous configuration of a sludge floc were constructed from the CLSM series images. The intrafloc flow field was simulated for the constructed floe model when it was subjected to a uniform flow field, based on which the Darcy's permeability was estimated. The permeability (K_DL) of original floe was estimated as 8×10^-12 m². Flocculated floes had higher K_DL due to their large pore size, while the corresponding values of K_DL of the freeze/thawed floes were lower. The calculated results indicate that a few large pores in the floc determine the permeability. The fractal dimension and compactness, however, are not correlated with the permeability of the flocs.
