A treatment system comprises a reactor vessel (2) wherein an aqueous solution is chemically treated using titanium dioxide catalytic particles in the solution, a membrane device (18) including tubular filtering membranes in communication with the vessel 2 for separating the particles from the solution by detaining the particles on entry-surfaces of the membranes, and a sparging device which causes injected air to flow over the entry surfaces to discourage clogging of the membranes by the particles. The reactor vessel (2) contains UV tubes (3) and the membrane device includes a coarse bubble aeration delivery device for producing slug pattern flow of the air over the entry surfaces of the membranes.
L~invention concerne un système de traitement comprenant un récipient de réaction (2) dans lequel une solution aqueuse est traitée chimiquement à l~aide de particules catalytiques de dioxyde de titane dans la solution, un dispositif à membrane (18) englobant des membranes de filtrage tubulaires en communication avec le récipient (2) pour séparer les particules de la solution en retenant les particules aux surfaces d~entrée des membranes, et un dispositif de barbotage conduisant de l~air injecté à s~écouler au-dessus des surfaces d~entrée pour prévenir l~obstruction des membranes par les particules. Le récipient de réaction (2) contient des tubes UV (3) et le dispositif à membrane comprend un dispositif d~administration d~aération à bulles grossières pour produire un écoulement d~air à motif ralenti sur les surfaces d~entrée des membranes.
