<p>The present invention relates to an electroflocculation apparatus. The present invention also relates to waste-water treatment systems which include an electroflocculation stage. The present invention is predicated, in part, on the recognition that a perforated cathode may be used as a sieve to separate floe generated during electroflocculation from an electrolyte in an electroflocculation apparatus. In some embodiments, the present invention also recognizes that rising bubbles of gas produced at the cathode during electroflocculation serve to lift off, or otherwise dislodge, sieved floe from the cathode and/or prevent the buildup of floe on the perforated cathode. In this way, blockage of the perforated cathode by the buildup of floe is reduced or eliminated.</p> |
