Abstract: A cylindrical-shaped tank has a grate of electrodes disposed horizontally across the open circular cross section thereof and at least one distributor arm is mounted to revolve in a horizontal plane above the grate of electrodes for evenly distributing liquid to be treated. By electrolysis of the liquid, a uniform upward flow of gas bubbles is produced to lift suspended solids and immiscible liquid to the surface of the liquid within the tank, while clarified liquid sinks downward between the bubbles towards the bottom of the tank.
