The movement of liquid through a porous material or membrane caused by electrical current, used to separate or dry materials.
From electro- + endosmose (from Greek endon 'within' + osmos 'push, thrust'). The term emerged in 19th-century electrochemistry to describe the surprising liquid movement created by electrical fields.
Electroendosmose can literally squeeze water out of clay or soil using electricity—it's how engineers now dry contaminated earth and how some modern water purification systems work.
