Abstract

Les procédés, systèmes et appareil selon l'invention utilisent des sels communs naturels qui sont électrochimiquement activés (ECA) dans une solution aqueuse afin d'obtenir une solution de produit ECA qui est sans danger et non toxique. L'utilisation d'un sel d'halogénure métallique, tel que NaCl, avec de l'acide acétique peut conduire à la production d'un antiseptique ou d'un désinfectant à pH et FAC variable, mais présentant une propriété de longue durée de conservation.
