Abstract
Electrofiltration has established itself as an energy efficient unit operation in ultrafine particle dewatering. The Dorr-Oliver Electrofilter combines vacuum cake filtration with electrophoresis and electroosmosis. This results in an order of magnitude drop in energy use when compared to traditional dewatering methods. Commercialization of this unit operation is progressing rapidly in several energy intensive industries.
