Abstract
The invention relates to a method for controlling of a biofilm, for removing a formed biofilm and/or for controlling a growth of microorganisms, preferably bacteria, in an aqueous environment of an industrial manufacturing process comprising cellulosic fibre material. In the method a composition comprising a compound selected from a group consisting of 3-[(4-methylphenyl)sulphonyl]-2-propenenitrile and 4-amino-N-2-thiazolyl-benzenesulphonamide is administered to the aqueous environment of the process.
Claims15
A method to control formation of a biofilm in an aqueous industrial manufacturing environment comprising cellulosic fibers and having a temperature of at least 40° C., the method comprising a step of continuously or periodically adminstering to the aqueous environment a composition comprising 3-[(4-methylphenyl)sulphonyl]-2-propenenitrile as an active compound wherein the aqueous industrial manufacturing environment is an aqueous environment in manufacturing paper, board, pulp, tissue, or non-woven or viscose.
