INHIBITING BIOFILM FORMATION BY THERMOPHILIC MICROBES IN PAPER AND BOARD MACHINES

摘要

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 surface s 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.
