Abstract
The zonal concentration of solids in an aqueous dispersion is increased through the use of electroendosmosis. In the aqueous dispersion, a first cathode means, an anode means, spaced from the first cathode means, a second cathode means, intermediate the first cathode means and the anode means, and means for establishing a direct current electrical potential between the first and second cathode means and the anode means, is provided wherein electroendosmosis may be used to increase the density of solids within aqueous dispersions covering areas greater than twelve meters in diameter.
