1. Biomedical electrolysis apparatus for cyclic controlled current, controlled potential electroly tic oxidation of a metabolic waste comprising in operative combination:

  • (a) a continuous electrolysis cell having at least two continuously conductive electrodes including a working and a counter electrode, said cell being adapted for continuous flow therethrough, without disruption, of an aqueous media having said metabolic waste to be electrolyzed;

    (b) means for providing a controlled current, i+ to i-, between said working electrode and said counter electrode in contact with said aqueous media having said metabolic waste substance;

    (c) means for maintaining said controlled current i+ impressed on said electrodes for a period of time at least until a selected first voltage difference limit, V+, between said electrodes is achieved;

    (d) means for sensing the potential difference in said cell between said electrodes measured as voltage, V+ or V-;

    (e) means for sequentially cyclically reversing the direction of controlled current flow between said electrodes from i+ to i- in response to a predetermined voltage difference limit V+ or V- between said electrodes being sensed by said sensing means;

    (f) means for reversing the operating voltage domain of said working and counter electrodes(g) means for maintaining said reversed current i- impressed on said electrodes for a period of time at least until a selected second voltage difference limit, V-, between said electrodes is achieved; and

    (h) means for cyclically continuing reversals of said currents i+ and i- between said limits of said selected voltages v+ and v- to continuously electrolytically oxidize at least portions of said metabolic waste substance.
