A fluidized bed electrode system comprises an electrode chamber having a porous base, a main electrode consisting of a bed of fine solid particles contained in such chamber and selected from the group consisting of metals, metal coated glass beads and metal coated plastic beads, a current feeder extending into the bed, means for leading air or inert gas through the porous base at a predetermined velocity and pressure to fluidize the bed, and means for introducing a solution to be treated into the electrode chamber at a point above the porous base and for circulating such solution through the bed at a predetermined flow rate.
