摘要This study estimates the polymer-flocculated waste activated sludge floc interior permeability by observing the motion of individual flocs moving vertically towards an impermeable flat plate. The fluid flow fields surrounding and inside the flocs were modeled numerically and served as the basis for calculating the hydrodynamic drag force. Experimental data correspond to the numerical solutions regardless of the floc Reynolds number. According to our results, polymer flocculation produces large flocs with the same global interior structure as the original sludge flocs. The permeability range for flocs was also estimated based on the floc size investigated.
