1. A method for treating, in an apparatus free of a filter, chlorinated drinking water to be consumed by a user, the method comprising the steps of:
exposing a predetermined closed volume of the chlorinated drinking water only to an ultraviolet radiation of a wavelength within a range from 350 nm to 380 nm,
wherein the ultraviolet radiation breaks chlorinated molecules in the chlorinated drinking water; and
wherein the step of exposing a predetermined volume to the ultraviolet radiation is carried out long enough to provide at least 5.5 Wh of light energy per liter of drinking water.
