Methods for treating sessile microorganisms in a biofilm in a water system, for treating water, for remediating a typical water system housing microorganisms, water treatment composition, storage stable composition and concentrate
"METHODS TO TREAT SEVERE MICROORGANISMS IN A BIOFILM IN A WATER SYSTEM, TO TREAT WATER, TO REMEDY A TYPICAL WATER SYSTEM HAVING MICROORGANISMS, COMPOSITION TO TREAT WATER, COMPOSITION AND NOVEL COMPOSITION. The invention relates to methods and compositions for treating water systems, particularly recirculating water systems contaminated by a biofilm containing sessile microorganisms. The method includes the steps of forming a boron conditioned enzyme and contacting the biofilm with said boron conditioned enzyme, thereby planktonizing the microorganisms. The boron conditioned enzyme retains an activity level of at least 40% of the initial activity of the unconditioned enzyme for at least two hours after contacting the biofilm, either in the presence or absence of a biocide or corrosion inhibitor that normally would disable the enzyme. In preferred embodiments, a biocide is added to the conditioned enzyme. The method and compositions are also applicable to the remediation of lukewarm water systems in which a biofilm may harbor pathogens such as Legionella séssil.
