The application of electrical fields to dewatering and drying is reviewed. In particular, the developments in electroosmotic dewatering (EOD) of colloidal slurries are discussed in terms of fundamental associated phenomena, as well as the methods of enhancement of EOD. The electrohydrodynamic (EHD) drying of biological materials are discussed in terms of its fundamentals, current status, and advantages and disadvantages. The potential applications of this emerging technique are evaluated along with a discussion of R&D needs in these areas.
