Co-Flocculation of Mixed-Sized Colloidal Particles in Aqueous Dispersions Under a DC Electric Field.

When an electric field is applied to or removed from colloidal particle aqueous dispersions, a reversible increase in sedimentation velocity of the colloidal particles, referred to as the Electrically Induced Rapid Separation (ERS) effect, is observed.
