  • Radial flow electrofilter
    Patent number: 4302310
    Abstract: A radial flow electrofilter having a plurality of parallel planar horizontal electrodes. The filter may be provided with backflush means, in which case the filter medium preferably consists of non-deformable particles, or else a removable filter pack, preferably employing polyurethane foam, may be employed. In operation, finely divided solids, contained in a liquid of low electrical conductivity, may be efficiently removed by passing the liquid radially through the filter, while subjected to a unidirectional current electric field, from the periphery of the filter toward its center.
