Abstract

Elimination of phenols and other trace pollutants from drinking water and effluents by irradiating at 3500 A. Pref. wavelength is ca 2500 A. Pref. water is O2-satd, the pH is 0-6.5 or ca 14, and temp is 15-60 degrees C. Opt a sensitiser is used. Pref. layer of water irradiated is 0.1-30 esp. 0.5-30 cm. Process is carried out in one stage.
