Abstract
A composition-of-matter for use in water treatment, composed of a water-insoluble matrix and one or more amidohydrolase, such as cyanuric acid amidohydrolase, incorporated in or on the matrix, is disclosed. Also disclosed are devices containing same and methods utilizing same for water treatment. The water treatment is effected by an enzymatically-catalyzed reduction of the concentration of an amide-containing compound, such as cyanuric acid, found in chlorinated water of swimming polls, spas and other similar structures.
Claims14
A method of treating chlorinated water used in a circulating water reservoir, the method comprising passing the chlorinated water through a device comprising at least one casing having embedded therein a composition-of-matter comprising a water-insoluble matrix and, covalently attached thereto directly or via a spacer, both cyanuric acid amidohydrolase and biuret amidohydrolase, such that circulating chlorinated water flowing through said casing comes into contact with said composition-of-matter, so as to reduce a concentration of both cyanuric acid and biuret in the water, thereby treating the chlorinated water.
A method of treating chlorinated water used in a circulating water reservoir, the method comprising passing the chlorinated water through a device comprising at least one casing having embedded therein a composition-of-matter comprising a water-insoluble matrix and, covalently attached thereto directly or via a spacer, all amidohydrolase enzymes necessary to hydrolyze cyanuric acid all the way to CO2 and NH3 molecules, such that circulating chlorinated water flowing through said casing comes into contact with said composition-of-matter, so as to reduce the content of cyanuric acid and thereby treat the chlorinated water.
