It was found in our previous paper that an electrokinetic filtration could considerably increase the filtration flow rate in comparison with that of the conventional filtration, because electrophoresis in the slurry and electroosmosis in the cake were caused by the electric field. This method is especially applicable to the filtration of slurries such as bentonite slurry, which is difficult to filter by mechanical pressure because of gelatinous cake formation. Tn this experiment, an electrokinetic filter made by modifying an Oliver filter was used and its performance was investigated. Calcium carbonate, white clay and bentonite were used as suspended particles. As a result, it was confirmed that electrokinetic filtration is applicable to practical filtration and that the equation for the electrokinetic filtration proposed in this paper is applicable to the design of a practical filtration process.
