Abstract
Contaminated water is pumped through the anode compartment of an electrolytic cell which is separated from the cathode compartment by a diaphragm permeable to water and to inorganic ions. Particles of hydrophilic, electrically conductive, carbonaceous material capable of adsorbing the contaminants are retained in the anode compartment by the diaphragm and by screens in the water discharge conduit and are held in turbulent suspension by the flowing water so that they make intermittent conductive contact with the anode surface.
