Title (EN) TREATMENT SYSTEM AND METHOD FOR REMOVING CHALLENGE MATERIALS FROM A WATER STREAM
(FR) SYSTÈME DE TRAITEMENT ET PROCÉDÉ DE SUPPRESSION DE MATÉRIAUX D'ESSAI DANS UN COURANT D'EAU
Abstract:
(EN) A treatment system (200) for removing challenge materials from a water stream is provided. The treatment system (200) includes a treatment facility (202) configured to receive a water stream, a photo-electro-chemical oxygen demand device (205) positioned downstream of the treatment facility (202) and configured to measure an oxygen demand in the water stream after treatment by the treatment facility (202), and a challenge treatment facility (209) positioned downstream of the photo-electro-chemical oxygen demand device (205) and configured to perform a challenge treatment process on the water stream. If at least one challenge material is detected by the photo-electro-chemical oxygen demand device (205), then the challenge treatment facility (209) performs the challenge treatment process on the water stream.
(FR) L'invention concerne un système de traitement (200) destiné à supprimer des matériaux d'essai dans un courant d'eau. Le système de traitement (200) comprend une installation de traitement (202) conçue pour recevoir un courant d'eau, un dispositif de demande en oxygène photoélectrochimique (205) positionné en aval de l'installation de traitement (202) et conçu pour mesurer une demande en oxygène dans le courant d'eau après traitement par l'installation de traitement (202), et une installation de traitement d'essai (209) positionnée en aval du dispositif de demande en oxygène photoélectrochimique (205) et conçue pour effectuer un processus de traitement d'essai sur le courant d'eau. Si au moins un matériau d'essai est détecté par le dispositif de demande en oxygène photoélectrochimique (205), alors l'installation de traitement d'essai (209) effectue le processus de traitement d'essai sur le courant d'eau.
