This thesis describes the experimental procedure and results of an investigation into the effect of electric and acoustic fields on dead end vacuum filtration. The test suspension used was low concentration titanium dioxide. Ultrasound energy was applied tangentially and electrical energy parallel to the filter medium. Varying electric field gradients were applied to the filter cell, either alone or together with the constant frequency acoustic field. The filter cell was based on a Nutsche filter, and allowed samples of cake to be taken at the end of the filtration experiment. Electric and acoustic field strengths, suspension characteristics and process parameters could all be varied independently. [Continues.]
