Biofilm avoidance and removal process and composition

The present invention relates to the use of at least one enzyme component from the group consisting of carbohydrases, proteases, lipases and glycol proteases and a short-chained glycol component for the avoidance of slime formation and/or for the removal of biofilm on surfaces of water-bearing syste...

Beschreibung
Zusammenfassung:	The present invention relates to the use of at least one enzyme component from the group consisting of carbohydrases, proteases, lipases and glycol proteases and a short-chained glycol component for the avoidance of slime formation and/or for the removal of biofilm on surfaces of water-bearing systems, in particular of industrial process-water systems. The enzyme component(s) and the glycol component can be added to the water-bearing system either separately, i.e., at different points, or in the form of an enzymatic composition containing the enzyme component(s) and the glycol component.
