Abstract
A multiplicity of electrode plates, anodic and cathodic, are alternately arranged in an electrolytic tank side by side at short intervals in a row. A circulating current of the sludge being treated is caused to be produced within said electrolytic tank. Said circulating current including an upward current flowing upward between individual electrode plates and a surface current flowing above the row of the electrode plates and near the surface level of the sludge in a specified direction. Gas bubbles produced between the individual electrode plates and flocs present between the electrode plates are carried to the surface of the tank by said upward current. The surfaced bubbles and flocs being then carried by said surface current to a location which is generally outside the surface area above the elecrode plates. Air bubbles thus collected at one side of the electrolitic tank are beaten out by a shower of sludge falling thereon.
