Method and apparatus for producing high volumes of clean water by electro coagulation

An electrolytic apparatus for removing contaminants from influent water, comprising:

• a reaction chamber (54, 112, 114) having a means (84, 118) for admitting water and means (84, 120) for discharging water (84, 120);
• a set (110) of spaced apart conductive electrodes (40) in said reaction chamber (54, 112, 114), arranged in first and second groups of electrodes, each group containing a plurality of electrodes, with electrodes (40) of the first group interleaved in alternating sequence with electrodes (40) of the second group, defining a flow path in a flow direction between an electrode (40) of the first group and a juxtaposed electrode of the second group, said flow path extending within said reaction chamber from said means (84, 118) for admitting water toward said means (84, 120) for discharging water;
• polarizing means (34, 36) for initially, oppositely polarizing at least some of said electrodes (40) in each of said first and second groups of said set (110);
• and wherein
• said first and second groups of electrodes (40) are interleaved such that an electrode (40) of the first group is the first electrode (150) of the set (110), and an electrode (40) of the second group is the last electrode (150) of the set (110);
• said polarizing means (34, 36) is connected to apply a first polarity to said first electrode (150) and to apply a second and opposite polarity to said last electrode (150);
• and
• the polarizing means (34, 36) is electrically disconnected from remaining electrodes (151) of the first and second groups;
• and wherein said polarizing means further comprises:
• selectively actuatable means (38) for reversing polarity of said initially polarized electrodes (40) in each of said first and second groups of said set (110);
• and
• means (42) responsive to selective actuation of means for reversing polarity, for capacitively discharging the initial polarization of the initially polarized electrodes (40).
