Abstract: A chlorination electrolyser having a housing provided with an inlet and an outlet suitable for the circulation of brine; at least one pair of bipolar electrodes facing each other and positioned within said housing. Each bipolar electrode of the at least one pair has a valve metal substrate; an active coating comprising at least one layer of a catalytic composition comprising ruthenium and titanium disposed over the substrate; a top coating having at least one layer composed of oxides of tantalum, niobium, tin, or combinations thereof disposed over the active coating. A self-cleaning electrochlorination system having the an electrolyser, a method for its production, its use in normal and low salinity pools for hypochlorite mediated water disinfection and a method for hypochlorite-mediated water disinfection.

Abstract: The present invention relates to an electrode for electrochlorination processes, optionally operable under polarity reversal conditions, comprising an active layer provided with a doped Ru—Ti catalytic composition.
