Structural Analysis Of Sludge Floc
Author(s)
D.J. Lee
Abstract
Free settling tests, small angle light scattering (SALS), microtome-slicing
techniques, and confocal laser scanning microscopy (CLSM) were performed to
examine how the cationic flocculation or freezing and thawing affected the floc
structure. The floc size, internal pore size, mass fractal dimensions determined
from free-settling test or small angle light scattering test, aeral porosity,
boundary fractal dimension and Sierpinski carpet fractal dimension of pore
boundary from 2D slices, and the volume porosity, compactness, and the pores’
box-counting fractal dimension from three-dimensional reconstructed image,
were estimated and compared.
Keywords: floc structure, freezing, flocculation, image analysis.
1 Introduction
Sludge flocs are highly porous fractal-like aggregates of many primary particles
[1]. Li and Ganczarczyk [2] sliced the activated sludge flocs to examine
