Embodiment Construction

[0027] The invention relates to a method for electrochemical disinfection of water by passing said water through at least one electrolytic cell housed in a housing provided with means for delivering and removing said water, and Utilizes direct viricide, bactericide and bacteriostatic effects associated with oxidation at the anode and reduction at the cathode and supplementary indirect bactericidal and residual bacteriostatic effects associated with the action of oxidizing agents produced by electrolysis of water.

[0028] The method of the present invention is essentially characterized in that it comprises:

[0029] a) Using an electrolytic cell comprising an anode and a cathode, both plate-shaped and parallel to each other, the opposing catalytic faces of said anode and cathode have the same surface area and form a symmetrical inter-electrode space, with no preferred path or short circuit;

[0030] b) along the entire length of the channel of the water to be treated, between...

Abstract

The invention relates to a method for the electrochemical disinfection of water by passing it through at least one tank housed in a housing provided with means for conveying and removing the water. The process of the invention is characterized in that it comprises: a) the use of an electrolytic cell having an anode and a cathode, both plate-shaped and parallel to each other, the opposing catalytic faces of said anode and cathode having the same surface area and forming symmetrical electrodes between the plates without preferred paths or short circuits; b) along the entire length of the channel of the water to be treated, a turbulent state of flow is created between the plates which alternately and successively will contain the dissolved The action of the microorganisms in the substance projected towards the anode and the cathode such that they experience a deactivation effect caused by the strong pH changes that exist between the electrodes and an additional Bactericidal effect.

Description

technical field [0001] The present invention relates to a method for the electrochemical disinfection of water, without the addition of any chemicals, by passing the water through at least one electrolytic cell housed in a housing provided for delivery and removal The water device, and utilizes direct viricide, bactericide and bacteriostatic effects associated with oxidation in the anode and reduction in the cathode, and supplementary indirect bactericidal and residual bactericidal effects associated with the action of oxidants produced by electrolysis Bacteriostatic effect. Background technique [0002] Patent EP1597202 with the same applicant describes a method: [0003] - it consists of passing the water to be treated continuously through an electro-peroxidation module, by means of catalytic electrodes, whereby the water undergoes an electrochemical treatment; [0004] - On the one hand, the direct effects (virucide, bactericide and bacteriostatic effect) acting on the ...
