Abstract

Sensibilisateur de photosensibilisation et procédé et dispositif le mettant en oeuvre. Dans un réservoir à eau, on introduit un liquide 3 à traiter contenant des organismes vivants et on expose ce liquide à une irradiation par une lumière visible, telle que la lumière du soleil, en la présence d'oxygène. Sur les parois du réservoir 1 à eau, sont placés des inhibiteurs 2 qui, sous l'effet d'une lumière visible, permettent d'obtenir une stérilisation efficace. Traitement des piscines.
