Abstract
Systems and methods for reducing biofilms are described. The systems and methods are particularly suitable for use with conventional aqueous crossflow filtration systems, such as reverse osmosis systems. The addition of the enzyme/surfactant compound has been found to enhance the effectiveness of conventional crossflow filtration processes by decreasing or inhibiting the growth of biofilms and other contaminants.
Claims9
A method for reducing biofilm in an aqueous system, comprising the steps of:
- providing a mixture containing a surfactant and a yeast fermentation product, said yeast fermentation product comprising a product of the fermentation of a yeast selected from the group consisting of Saccharomyces cerevisiae, Kluyveromyces marxianus, Kluyveromyces lactis, Candida utilis (Torula yeast), Zygosaccharomyces, Pichia, and Hansanula, and introducing the mixture to an aqueous system containing biofilm.
