  • Radial flow electrofilter
    Patent number: 4269681
    Abstract: A radial flow electrofilter having a vertical cylindrical fluid distributor means adapted to serve as a grounded electrode, a vertical central tubular collector also adapted to serve as an electrode and at least one, preferably a plural odd number, of permeable cylindrical electrodes concentrically positioned between the distributor and the collector. The filter medium preferably consists of non-deformable particles, the filter being provided with backflushing means. In operation, finely divided solids, contained in a liquid of low 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.
