Do I need UV lights to purify fresh water produced by desalinator ?
A. In nearly all cases, U.V. light or any further treatment of water in unnecessary. The UV light only kills bacteria which rarely exists in the reverse osmosis processed water. It is recommended that the desalinator membranes be cleaned periodically to prevent internal growth of bacteria. For prolonged storage of drinking water, chlorination is necessary regardless of UV light disinfection of the freshly purified water. UV light has no preservative action.
