A study of dead-end filtration enhanced by electric and acoustic fields
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.
