Description: The results indicate that biofilm had always a higher density, geometric porosity, and a larger boundary fractal dimension than flocs. Both types of biomass were found to exhibit at least two distinct Sierpinski fractal dimensions, indicating two major different pore space populations. With the increasing wastewater flow, both types of biomass were found to shift their structural properties to larger values, except porosity and surface roughness, which decreased. Floc density and biomass Sierpinski fractals were not affected much by the system loadings.This study investigates the structural features of biomass present in hybrid form in the same pilot-scale aeration tank. The attached-growth biomass was characterized by biofilm thickness, density, porosity, inner and surface fractal dimensions. The suspended-growth biomass was analyzed by floc size distribution, density, porosity, inner and surface fractal dimensions. The study was carried out in two subsequent periods, which differed in hydraulic and substrate loadings.
