CA 2248280

There is disclosed a system for separating oil and other immiscible contaminants from a liquid body containing the contaminants such as a water body. The system includes the use of a plurality of microporous hollow fibers which may be arranged in any number of arrangements such as bundles, intersecting arrangements, divergent patterns or in a mat-like arrangement or a combination of the foregoing. The hollow fibers are in communications with a source of pressure in order to force the contaminant via the pores into the fibers for subsequent storage in a suitable container. By incorporating acceptable means of density control a substantial amount of the hollow fiber surface area may be exposed to the contaminant thus increasing the extraction efficiency of the contaminant from the water body. The unit optionally may be self-contained. Thissystem provides a substantial advantage over existing arrangements in that extraction efficiency is greatly enhanced in any number of environments. The system and methods are also useful in recovering crude oils, metals or other dissolved components, etc., from the aqueous phase.

Cette invention concerne un système de séparation d'huile et autres contaminants non miscibles d'un plan d'eau par exemple. Le système fait appel à des fibres creuses microporeuses assemblées de différentes façons : en faisceau, en croisé, en rangées divergentes ou parallèles, ou selon une combinaison de ces agencements. Les fibres creuses sont reliées à une source de pression négative servant à forcer les contaminants à y pénétrer par leurs pores en vue de leur stockage ultérieur dans un récipient approprié. En intégrant au système un moyen acceptable de régulation de la masse volumique, on peut faire en sorte d'exposer une part considérable de la surface des fibres creuses au contaminant et ainsi accroître l'efficacité du procédé de dépollution du plan d'eau. Le système envisagé peut être du type autonome. Il présente un avantage certain par rapport aux systèmes antérieurs du fait d'une efficacité d'extraction hautement améliorée dans tous les types d'environnements. Il s'avère également utile pour séparer le pétrole brut, les métaux et d'autres éléments dissous de la phase aqueuse.
