The instant invention is a decontaminating process for reducing the surface tension of a biofilm allowing for the removal of the biofilm and control of underlying bacteria. A solution consists of saponin and a soft acid such as food grade sodium lactate. The saponin acts as a foaming agent providing surface tension reduction capable of loosening the biofilm. The solution is preferably applied by a mechanical device providing an efficient coating of the surface to be treated allowing a reduced amount of the lactate acid to be used allowing the acid to make contact with the bacteria while stripping away of the biofilm is made possible.

La présente invention se rapporte à un procédé de décontamination permettant une réduction de la tension superficielle d'un film biologique, le retrait du film biologique et la régulation des bactéries sous-jacentes. On utilise une solution composée de saponine et d'un acide doux tel que le lactate de sodium de catégorie alimentaire. La saponine joue le rôle d'un agent moussant assurant une réduction de la tension superficielle et par conséquent un certain relâchement du film biologique. On applique de préférence cette solution au moyen d'un dispositif mécanique assurant une enduction efficace de la surface à traiter, ce qui permet de n'utiliser qu'une quantité réduite d'acide lactique, ledit acide ayant la possibilité d'entrer en contact avec les bactéries alors que le retrait du film biologique est rendu possible.
