Abstract
The disinfecting effect of electric current passing between a contaminated aqueous liquid and an anode immersed in the liquid is enhanced by providing bipolar electrodes between the directly energized anode and cathode so that the flow channels for the liquid between the electrode faces are limited to a width of 3 mm or less, the auxiliary electrodes being insulated from each other and from the directly energized electrodes and disposed in such a manner that the potential difference between each pair of adjacent electrodes is equal.
Claims10
Apparatus for destroying microorganisms in an aqueous liquid comprising:
- a. a vessel bounding a cavity;
- b. a row of electrodes mounted in said cavity in spaced, electrically insulated relationship and including two terminal, main electrodes and at least one auxiliary electrode interposed between said main electrodes,
- 1. each main electrode having a face spacedly opposite the corresponding face of the other main electrode,
- 2. said at least one auxiliary electrode having two faces substantially parallel to said respective faces of said main electrodes, said two faces being arcuate about a common axis of curvature, the axes of curvature of the faces of said at least one auxiliary electrode substantially coinciding,
- 3. respective faces of each pair of adjacent electrodes in said row defining therebetween a channel for flow of liquid parallel to the defining faces;
- c. conductive means for connecting said main electrodes to respective terminals of a source of electric power and for thereby establishing a voltage between said main electrodes;
- d. inlet means and outlet means on said vessel for simultaneously passing therebetween respective portions of a stream of aqueous liquid through said channels, each of said portions providing the sole path of electric current between the pair of electrodes defining the associated channel.
