On techniques for the measurement of the mass fractal ...

2002-1-15  3. Techniques for aggregate mass fractal dimension determination. A number of techniques have appeared in the literature to determine the mass fractal dimension of aggregates of fine particles. Here we give details on the three most common techniques: (light) scattering, settling and image analysis.

The large drop in DO concentration of 22–80% between the bulk liquid and aggregate surface demonstrates that the external mass transfer resistance is also highly important. The maximum OUR even for floccular biomass was only attained at much higher DO concentrations (≈8 mg/L) than typically used in such systems.
