Abstract
L'invention concerne une installation de traitement pour eau de grande pureté (100), traitant une charge de fluide à contaminant d'azote organique, par contact avec une unité d'élimination ciblée (30), dans le but de faire tomber en-dessous d'un seuil une concentration à l'état de traces. L'unité d'élimination peut comprendre une enzyme ou un autre agent, libre ou en liaison, qui a une efficacité spécifique pour rompre le contaminant. Il s'agit de préférence d'une enzyme stabilisée, immobilisée ou protégée, de sorte que son intégrité, ou au moins son activité, soit maintenue pendant plusieurs heures, plusieurs jours, ou plus longtemps, sans cofacteur, et avec une grande efficacité. Ce système est utile pour l'élimination de l'urée, dans le cadre d'un processus de lithographie à autocatalyse ou de préparation pharmaceutique. Par exemple, l'enzyme est une uréase lyophilisée/cristallisée, que l'on peut mettre en contact avec le flux par injection directe, ou bien l'enzyme peut transiter via une cuve de réaction ou une conduite de mélange à retard, afin que le temps de contact soit approprié, pour la rupture ou la capture du contaminant. On peut immobiliser l'enzyme sur un support, par exemple une membrane ou des billes, ce qui permet de faire passer le flux sur des billes, dans une colonne ou sur une surface, de manière à réaliser le clivage de l'urée dans la charge de fluide. On peut également utiliser des microparticules résidant dans le fluide, elles-mêmes séparées et réutilisées. Lorsqu'on utilise une enzyme libre ou liée à des microparticules, il est possible de récupérer le substrat de microparticules comme rétentat depuis une unité d'hyperfiltration (215) ou autre unité de filtration en aval ou en boucle latérale. On peut aussi récupérer le rétentat dans une cuve de dépôt et réutiliser le produit pour la réaction afin de maintenir une forte concentration d'enzyme ou d'agent, en fonctionnement.
