Feb 13, 2018· Sedimentation leads to the separation of the continuous and dispersed phases (phase separation), resulting in the formation of a particle sediment bed. Similarly, phase separation can occur when the dispersed phase is less dense than the continuous phase, with the dispersed phase rising to the top in a process known as creaming.
