Patent
CA 2503648
The inention relates to a method of inhibiting the biofim formation by thermophilic adhering microbes of paper and board machines on the surface of peper or board machines, and /or removing such biofilms from th said surfaces by a dding to the circulation waters of the paper or board machines at least one pure substance isolated from a plant or at least one plant extract or a mixture thereof in such a concentration which is effective against thermophilic adhering microbes. The invention further relates to a method of determining the need of the addition of an anti-biofilm agent in paper and board manufacturing prcesses, and an assembly kit suitable for the same.
L'invention concerne un procédé qui permet d'inhiber la formation d'un film biologique par des microbes thermophiles adhérents à la surface de machines à papier ou à carton, et/ou de retirer le film biologique desdites surfaces par adjonction aux eaux de circulation des machines à papier ou à carton d'au moins une substance pure isolée d'une plante ou au moins d'un extrait de plante ou de leur mélange, selon une concentration propre à neutraliser les microbes thermophiles adhérents. L'invention concerne en outre un procédé qui permet de déterminer la nécessité d'ajouter un agent anti-film biologique dans des processus de fabrication de papier ou de carton, et un ensemble d'accessoires pour mettre en oeuvre le procédé.
