  • Patent number: 6267885
    Abstract: The invention provides a liquid purification apparatus (10) adapted to employ the combination of the purifying effects of the heavy metals copper and silver in conjunction with hydrogen peroxide and the catalytic reaction thereof. A body means (11, 12) defines a flow passage (13) having a liquid inlet (14) at one end and a liquid outer (16) at the other end. Flow passage (13) has a first electrolytic unit (60) containing at least one copper based anode (22) and a second electrolytic unit (62) containing at least one silver based anode (25) spaced downstream of first electrolytic unit (60). An electrical circuit means (32) supplies operating current thereto and flow passage (13) includes an inlet (34) for the controlled introduction of H2O2 from reservoir means (51) into flow passage (13) between first (60) and second (62) electrolytic units.

  • Patent number: 6022459
    Abstract: The invention relates to a liquid purification apparatus (10) adapted to employ the purifying effects of the heavy metal silver under electrolysis. The apparatus (10) has a chamber (14) formed with spaced apart inlet and outlet openings (16,18) whereby liquid can flow through chamber (14) from inlet opening (16) to outlet opening (18). An electrolytic unit (20) has at least two spaced apart silver electrodes (22,24) mounted in chamber (14) in the path of the liquid flow. An electric circuit means (32) controls operation of electrodes (22,24) with a first timing means (62) for providing a pulsed current to electrodes (22,24).
