Abstract

L'invention concerne une composition et des procédés d'utilisation de celle-ci, la composition comprenant : une source d'halogène, de l'urée et un agent stabilisateur d'halogène supplémentaire à l'exception de l'urée, éventuellement un alcali dans une concentration suffisante pour doter ladite composition d'un pH supérieur à 10 ; et éventuellement l'exclusion d'un composé du brome stabilisé à partir de ladite composition. De plus, l'invention concerne un procédé de réduction de l'activité biologique dans un courant de traitement. Le procédé comprend : l'apport d'une composition à un courant de traitement, ladite composition contenant : un halogène, de l'urée et un agent stabilisateur d'halogène supplémentaire à l'exception de l'urée, éventuellement un alcali dans une concentration suffisante pour doter ladite composition d'un pH supérieur à 10 ; et éventuellement l'exclusion d'un composé du brome stabilisé à partir de ladite composition. L'invention concerne également des compositions et des procédés d'utilisation en tant qu'agents biocides efficaces pour des courants d'eau. La composition comprend une source d'halogène, des agents stabilisateurs d'halogène contenant des espèces portant du soufre et des sels d'ammonium/de l'urée et un alcali. Les espèces portant du soufre comprennent de l'acide sulfamique et son équivalent salin. Le rapport entre le mélange d'azote des espèces portant du soufre et des sels d'ammonium ou de l'urée peut être optimisé à n'importe quelle vitesse. Grâce à un rapport de mélange optimisé d'halogène à l'agent stabilisateur et un rapport de mélange des sels d'ammonium à l'acide sulfamique ou au sulfamate, un effet synergique a lieu qui, à la fois, améliore l'efficacité de la composition en tant que biocide et évite des impacts indésirables sur d'autres produits chimiques qui sont présents dans le courant d'eau (tels que des additifs du papier dans la pâte et les courants d'eau pour la fabrication de papier). Avant tout, la composition est facile à former et facile à introduire dans un courant d'eau approprié. Son introduction peut être aussi simple que le mélange de deux récipients de réactif avant l'introduction dans le courant de traitement d'eau.
