Abstract:
A method for providing a dose of visible light in covered drinking water storage facilities to control nitrification. In one embodiment, the method includes irradiating the water with a dose of visible light sufficient to inhibit microbial nitrification of the water. In one embodiment, the dose of visible light has a wavelength from approximately 400 Hz to approximately 700 Hz. In another embodiment, the dose of visible light has a wavelength from approximately 550 Hz to approximately 700 Hz. In a further embodiment, the dose of visible light has a wavelength from approximately 380 Hz to approximately 430 Hz.
