High energy, highly collimated X-rays produced at the Cornell High Energy Synchrotron Sources (CHESS) enabled real-time suspended solids concentration measurements each second with 0.5 mm vertical separation in a kaolin filter cake. Suspended solids concentration profiles reflected expected effects of cumulative fluid drag forces. Shrinkage caused a significant increase in average cake suspended solids concentration after expiration of the slurry, and the saturated cake ultimately formed was virtually homogeneous. Shrinkage is consolidation under compressive forces created when capillary menisci form at air/liquid interfaces, and has a significant effect on cake structure in latter stages of compressible cake filtration.
