TI  - Advective flow in spherical floc.
PG  - 451-9
AB  - Numerous structural models of flocs, such as homogeneous model or 
      radially-varying model, were proposed in literature for predicting the extent of 
      advective flow on the intrafloc transport processes. This work probed the 
      three-dimensional structure of original and chemically flocculated wastewater 
      flocs using the fluorescence in situ hybridization (FISH) and the confocal laser 
      scanning microscope (CLSM) techniques, from which the spherical mesh model on 
      real floc structure was constructed. Simulation results revealed that if an 
      average characteristic of sludge floc, such as porosity or drag force correction 
      factor of sludge floc is of concern, both homogeneous or radially-varying models 
      may be able to apply, particularly for those flocs that were closely compacted. 
      However, the detailed flow patterns inside real floc are much more tortuous than 
      those of the homogeneous or radially-varying models. If local hydrodynamic 
      environment within the floc is of interest, then only the complicated structural 
      model with real floc could be applicable.
