ABSTRACT:
A method of eliminating bacteria from water without resort to chemicals. The method is carried out by: mixing into the water a dye which stains bacteria contained in the water; and irradiating the water containing the dye with radiation at a wavelength which is absorbed more highly by the dye than by water and at a radiation power density sufficient to vaporize at least a significant proportion of the dye and the bacteria stained by the dye.
