Abstract

Apparatus includes treatment chamber including at least one outlet for exit of electrochemically treated liquid, and a liquid disperser having a plurality of liquid passageways, wherein each said liquid passageway includes at least one inlet to the treatment chamber for entry of a liquid to be treated; and a plurality of electrodes positioned within the treatment chamber for electrochemical treatment of the liquid.

Claims19

Dependent claims

An electrochemical liquid treatment apparatus comprising:

a treatment chamber containing at least one inlet for entry of a liquid to be treated, and comprising at least one outlet for exit of electrochemically treated liquid;
a plurality of electrodes comprising at least one anode, at least one cathode, and at least one electrical conductor positioned intermediate said anode and said cathode;
at least one electrode holder holding electrodes comprising:
(i) at least one electrical conductor;
and (ii) at least one anode and/or at least one cathode;
wherein the at least one electrode holder is slideable between:
(i) a holding position in which the electrode holder is engaged with the treatment chamber and said electrodes held by the electrode holder are positioned within the treatment chamber for electrochemical treatment of the liquid;
and wherein at least two of said electrodes held by the electrode holder are configured to be differently charged so as to define an electrochemical treatment zone in a liquid passageway therebetween;
and
(ii) a released position in which the electrode holder is not present in the treatment chamber;
and
a flow aligner positioned intermediate the at least one inlet and the plurality of electrodes when the at least one electrode holder is in the holding position, wherein the flow aligner includes a wall defining a plurality of apertures for passage of the liquid;
and wherein the flow aligner is configured to align the flow of the liquid into the liquid passageway between the at least two electrodes and substantially along a longest axis of at least one of the at least two electrodes;
wherein, when the at least one electrode holder is in the holding position, the treatment chamber includes at least one power connector for connecting power to said anode or said cathode held by the at least one electrode holder;
and
wherein, when the at least one electrode holder is in the holding position, the at least one power connector includes a resilient metal flexed against said anode or said cathode to thereby connect power thereto without use of a screwed connector.
