Abstract
Droplet breakage in emulsification occurs as the result of work performed against surface tension by dynamic pressure fluctuations while deaggregation in biological wastewater treatment occurs in response to hydrodynamic stresses imposed by aeration, recirculation, and mixing. Such size reduction in the latter case leads to solids carry-over and poor process performance due to reduced sludge age. Laboratory observations of the disintegration process have shown how the hydrodynamic environment causes breakup and lean, batch breakage studies have indicated the most probable sizes of fragments. A Monte-Carlo type simulation has been used successfully to model the breakage process in both liquid-liquid and solid-liquid systems under high dissipation conditions. © 1984, Taylor & Francis Group, LLC.
