Abstract
An apparatus for promoting reactions between particles suspended in a liquid is provided. The apparatus includes a treatment cell having an electrode array. The suspension of the particles is fed to the treatment cell by feeding means. The liquid is removed from the treatment cell by removing means. The feeding means is connected to the electrode array in the cell and adapted to generate a first non-uniform electrical field, at a first frequency, within the cell. The removing means is connected to the electrode array in the cell and adapted to generate, within the cell, a second non-uniform electrical field, at a second frequency which is different from the first frequency. The apparatus further includes means for simultaneously applying at least the first non-uniform electrical field, at the first frequency, and the second non-uniform electrical field, at the second frequency.
