A fluid treatment device, particularly useful for ultraviolet radiation treatment of fluids such as water. The device comprises a housing for receiving a flow of fluid. The housing has a fluid inlet, a fluid outlet, a fluid treatment zone disposed between the fluid inlet and the fluid outlet and at least one radiation source having a longitudinal axis disposed in the fluid treatment zone substantially transverse to a direction of the flow of fluid through the housing. The fluid inlet, the fluid outlet and the fluid treatment zone are arranged substantially collinearly with respect to one another. The fluid inlet has a first opening having: (i) a cross-sectional area less than a cross-sectional area of the fluid treatment zone, and (ii) a largest diameter substantially parallel to the longitudinal axis of the at least one radiation source assembly.
La présente invention concerne un dispositif de traitement de fluide convenant particulièrement au traitement par rayonnement ultraviolet de fluides tels que l'eau. Le dispositif comporte un logement permettant de recevoir un flux de fluide. Ce logement comporte une entrée de fluide, une sortie de fluide, une zone de traitement du fluide entre l'entrée et la sortie de fluide, et au moins une source de rayonnement dans la zone de traitement de fluide, sensiblement perpendiculaire à un sens d'écoulement du fluide traversant le logement. L'entrée de fluide, la sortie de fluide et la zone de traitement du fluide sont agencées sensiblement colinéairement les unes par rapport aux autres. L'entrée de fluide comporte un premier orifice comportant: (i) une surface en coupe inférieure à la surface en coupe de la zone de traitement du fluide, et (ii) un grand diamètre sensiblement parallèle à l'axe longitudinal de l'un au moins des ensembles de source rayonnante.
