Abstract

Pour lutter contre la croissance des algues, des champignons et des bactéries et contre la formation de résidus dans des conduites d'approvisionnement en eau pour installations de loisirs ou industrielles utilisant une eau à courants turbulents, un procédée de traitement de l'eau consiste à utiliser une composition contenant du biguanide de polyhexaméthylène et un agent tensio-actif. Ce procédé de traitement de l'eau et cette composition, contenant le biguanidine et l'agent tensio-actif, sont particulièrement utiles pour traiter des conduites d'approvisionnement en eau utilisées pour des loisirs, par exemple dans des sources thermales ou des piscines, où l'on utilise de l'eau à courants turbulents telle que de l'eau aérée.
