Abstract

The feasibility of using free-settling test for estimating activated sludge flee density was discussed in the present work. Some usually applied models or correlations, such as for the primary particle density, the drag coefficient, the correction factor for advection flow through the flee and the estimation for flee permeability, are examined. The results show that flee permeability depends strongly on the models or parameter sets applied. However, the effective flee density, and also the fractal dimension, is insensitive to the flee permeability estimation, but is strongly dependent on the drag coefficient expression employed. Possible valid experimental range is proposed.
