Le dispositif de l'invention pour réduire le potentiel redox de l'eau comprend des moyens d'amenée d'eau et deux électrodes verticales : une cathode cylindrique et une anode qui y est placée coaxialement qui forment entre elles une chambre électrolytique de circulation communiquant dans la partie supérieure avec les moyens d'évacuation des eaux usées. La cathode est faite de titane. L'anode est faite de graphite ou de shungite. Les électrodes sont placées dans une corps diélectrique de manière à former entre la paroi intérieure du corps et la surface extérieure de la cathode une chambre catalytique communiquant dans la partie supérieure avec des moyens d'amenée d'eau et, dans la partie inférieure, avec une chambre électrolytique. Les résultats techniques consistent à obtenir de l'eau potable très pure avec un pH neutre, un faible potentiel redox et une durée de vie longue ainsi qu'à simplifier la conception du dispositif de production de cette eau.
