Abstract

A plurality of individual treaters, each containing a pair of oppositely charged electrodes, are arranged circularly around a centrally disposed tank into which all of the treaters empty. A common supply manifold for all of the treaters brings waste water or other liquids into the system for treatment by any selected one of the treaters upon opening a control valve associated with such selected treater and closing control valves associated with the remaining treaters. Each treater contains an electrode that is constructed from a material differing from that of electrodes in the remaining treaters so that a particular treater may be selected for use based upon the predicted reaction of the material from which its electrode is made with the particular constituents of the waste liquid being treated. The central tank into which all treaters empty includes a pair of oppositely charged electrodes of its own to expose the once treated liquid to yet a second electric field, and there is a special structure associated with the lowermost discharge end of the electrode pair within the tank which is so arranged and configured that it reduces turbulence adjacent the floor of the tank such as to encourage settling out of floc produced by the treating process.
