Abstract

Den foreliggende oppfinnelse vedrører anvendelse av minst en enzymkomponent fra gruppen som består av karbohydraser, proteaser, lipaser og glykolproteaser og en kort-kjedet glykolkomponent for å hindre slimdannelse og/eller for å fjerne biofilm på overflater i vannbærende systemer, fortrinnsvis i industrielle prosessvannsystemer. Enzymkomponenten(e) og glykolkomponenten kan tilsettet til det vannbærende system enten separat, dvs. ved for- skjellige punkter, eller i form av et enzymatisk materiale inneholdende enzymkomponenten(e) og glykolkomponenten.The present invention relates to the use of at least one enzyme component of the group consisting of carbohydrases, proteases, lipases and glycol proteases and a short chain glycol component to prevent mucus formation and / or to remove biofilm on surfaces in water-bearing systems, preferably in industrial process water systems. The enzyme component (s) and glycol component may be added to the water-carrying system either separately, i.e. at various points, or in the form of an enzymatic material containing the enzyme component (s) and the glycol component.
