Abstract
An apparaatus and method for continuously removing liquid from an aqueous suspension; the apparatus consists of a filter housing; an electrofilter disposed within the housing to provide a crossflow chamber and filtrate chamber within the housing; an inlet for supplying a suspension to the crossflow chamber and an outlet for removing a suspension reduced in liquid content from the crossflow chamber, both the inlet and the outlet may be disposed so as to provide a crossflow of the suspension across the surface of the electrofilter or disposed to provide a batch process with optional stirring; and an outlet for removing liquid from the filtrate chamber. The method for continuously separating a liquid from an aqueous suspension while reducing membrane or filter fouling includes providing a crossflow apparatus having an electrofilter disposed therein; pumping the aqueous suspension into the crossflow apparatus at a pressure adapted to cause flow of filtrate through the electrofilter; and concurrently with pumping the suspension into the apparatus supplying electrical energy to the electrofilter at a voltage adapted to reduce fouling of the filter.
