Abstract: front page image
(EN)Systems and methods are provided for filtering a fluid containing nanoparticles. The systems and methods generally include introducing a stream of the nanoparticle- containing fluid into a holding vessel, and extracting at least a part of a nanoparticle- containing fluid accumulated in the holding vessel. The extracted nanoparticle- containing fluid is passed through a filtration module to separate a nanoparticle- containing retentate from a permeate, and the retentate is returned to the vessel. The filtration cycle can be repeated until a desired concentration of the nanoparticles is achieved in the holding vessel. In many embodiments, the generation of the nanoparticle-containing fluid and its filtration are performed concurrently.
(FR)L'invention concerne des systèmes et des procédés permettant de filtrer un fluide contenant de nanoparticules. Les systèmes et procédés comprennent de manière générale l'introduction d'un flux du fluide contenant les nanoparticules dans une cuve de rétention, et l'extraction d'au moins une partie du fluide contenant les nanoparticules accumulé dans la cuve de rétention. On fait passer le fluide extrait contenant les nanoparticules à travers un module filtration pour séparer un rétentat contenant des nanoparticules d'un perméat, et le rétentat est retourné vers la cuve. Le cycle de filtration peut être répété jusqu'à obtention de la concentration voulue des nanoparticules dans la cuve de rétention. Dans de nombreux modes de réalisation, la production du fluide contenant les nanoparticules et sa filtration sont mises en oeuvre simultanément.
