Electro-Osmotic Dewatering Some Experimental Aspects

ELECTRO-OSMOTIC DEWATERING SOME EXPERIMENTAL ASPECTS 

Streaming potential and migration or sedimentation potential comprise the second group and here the liquid or the solid phase moves relative to the other under the influence of a hydraulic or gravitational force, respectively, thus inducing an electrical potential difference across the medium. These four complementary electrokinetic phenomena are shown schematically in Fig. 5, which is taken from Yeung,25 and Yeung and Mitchell.22
