Abstract A state-of-the-art, high-speed video system has been used to observe floc disintegration occurring in the thin shear layer of a turbulent jet. The macrovideographic images have provided details of the breakage process that were heretofore unavailable. This information has been used to validate and quantify a force balance model that establishes a more rational framework for the description of floc breakage. It also has provided a much more detailed picture of the threshold levels of stress required for the breakage of specific floc structural types. The ultimate objective of this line of research is to use this framework to successfully describe the response of floc structures to hydrodynamic stress in coagulation processes and to provide a means by which substantial improvements can be made in solid-liquid separation processes.
