FIELD: technology of electroosmotic cleaning of capillary-porous media; may be used, in particular, in cleaning of coils and grounds with disturbed structure from contaminations such as heavy metals, phenols, acids, oil and oil products. SUBSTANCE: device has chamber for accommodation of cleaned medium with electrodes - anode and cathode to which DC source is connected, vessel with cleaning fluid in zone of anode, and collector for spent fluid. Chamber for accommodation of medium to be cleaned is expanded in direction from cathode to anode. EFFECT: higher efficiency. 5 cl, 6 dwg
