electrostatic separation sedimentation :

Electrostatic and hydrodynamic separation of aqueous

2002-9-1  In various industrial processes, sedimentation often plays a significant role in the separation of dispersed particles or drops from another immiscible liquid. This separation, taking place in large tanks, provides low operating cost when the residence time of the liquid–liquid system is long and the density difference between the two phases is large.

2018-2-13  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.
