APPARATUS FOR DEWATERING CLAY FILTER CAKE

摘要

An electrokinetic dewatering apparatus which includes a pair of oppositely electrically charged continuously traveling webs or belts (201), (301) positioned to contact a quantity of clay material passed into a nip (101) formed at the inlet to the dewatering apparatus. The clay cake is continuously contacted by the two webs (201), (301) while the cake passes therebetween. The clay material is not subjected to any pressure force substantially in excess of the contact pressure during the electrokinetic separation and removal of a portion of the water contained therein.
