ABSTRACT:
An improved method and apparatus for electrocoagulating waste water or fluids to remove colloidal suspensions therein is described. The apparatus includes at least one module having a plurality of closely spaced, flat electrodes defining a plurality of flow paths therebetween. Each pair of electrodes is separately mounted in the module and each electrode has a separate connection to a source of alternating current. Each pair may then be rapidly removed from the module for inspection, maintenance, or replacement or alternate pairs may be removed increasing the distance between the electrodes, if desired. The method allows the utilization of a fluidized bed of graphite particles to scrub the electrode faces, and it also permits the repelling forces on suspended solids to be broken on a continuous basis at relatively low current density in a collapsing field of alternating current. A relatively high volume flow rate of waste water or fluids may be rapidly and economically treated to remove contaiminants so that the treated waste water or fluid is suitable for disposal.
