Title
(EN) FLUID TREATMENT VESSEL
(FR) RÉSERVOIR DE TRAITEMENT DE FLUIDE
Abstract
(EN)
A fluid treatment apparatus comprising a tank containing a bed of at least one fluid treatment medium, a distributor plate separating the bed from an end portion of the tank, and an inert medium comprising amorphous particles having a harmonic mean diameter from 2.5 to 250 mm and a density from 0.57 to 0.998 cm3/g. The volume of the end portion containing inert medium is from 25 to 95% of the total volume of the end portion.
(FR)
Un appareil de traitement de fluide comprend un réservoir contenant un lit d'au moins un milieu de traitement de fluide, une plaque de distribution séparant le lit d'une partie d'extrémité du réservoir, et un milieu inerte comprenant des particules amorphes ayant un diamètre moyen harmonique de 2,5 à 250 mm et une densité de 0,57 à 0,998 cm3/g. Le volume de la partie d'extrémité contenant un milieu inerte est de 25 à 95 % du volume total de la partie d'extrémité.
