Multiscale structures of biological flocs
No full textThe three-dimensional pore structures in waste activated sludge floc were identifed using the fluorescence in situ hybridization and
confocal laser scanning microscope images. The interior of sludge floc was confirmed to have a multiscale structure, with pore cross-sectional
area of 15–20 ųm² as the transitional scale. Major advective flow would pass through the large pores, probed as a loosely packed, first
level structuration. The chemical flocculation would enlarge the aspect ratio of large pores, while freezing and thawing reduced it. The
second level structuration was comprised of fine pores with fractal boundaries, whose detailed structural information was extracted from
the constructed floc model. After flocculation, the boundaries of fine pores would become more irregular, and freezing and thawing
smoothed it. A sample calculation using the floc model demonstrated the intrafloc transport processes in flocs of multiscale structures
Bilevel thresholding of floc images
No full textFrequently encountered problems on bilevel thresholding of floc images include information loss during the image conversion stage, sampling
bias owing to spatially inhomogeneous luminous flux over an optical microscope image or among a series of images, thresholding error
adopting various algorithms, and resampling errors during three-dimensional reconstruction. Among these steps the choice of thresholding
algorithm could yield most of the processing error. Ways to reduce the potential processing errors are discussed
