Abstract
A hollow filter housing is provided with a support and a plurality of fiber bundles located on the support. The fibers extend within the filter housing in direction between an inlet and an outlet of the housing. The contaminated medium is introduced into the housing through the inlet in a direction towards the outlet to flow past the plurality of the fiber bundles. The contaminated medium becomes filtered as it passes through the filter bundles without compressing the latter against the support.
Claims31
A process for filtering a contaminated medium, comprising the following steps:
- (a) connecting a plurality of elongated filtering fiber bundles to a support within a hollow filter housing, which housing has an inlet and an outlet spaced apart from each other, the location of the support and the location of the fibers being such that the fibers extend substantially parallel to a flow path extending from the inlet to the outlet and passing through the fiber bundles;
- (b) introducing a contaminated medium into the housing through the inlet and causing it to travel through the fiber bundles along the flow path, whereby the medium is filtered;
- (c) maintaining the orientation of the fiber bundles during the filtration process in substantially their original positions in a manner that the fiber bundles do not become compressed against the support;
- and
- (d) withdrawing the filtered medium from the housing through the outlet.
2 more elements
A filter for filtering a contaminated medium, comprising:
- (a) a hollow filter housing having an interior and further having a first inlet and a first outlet, the first inlet communicating with the interior of the housing whereby a contaminated medium may be introduced into the interior of the housing and the first outlet communicating with the interior of the housing whereby the medium may be withdrawn from the interior of the housing after the filtration process;
- (b) a support located within the interior of the housing;
- (c) a plurality of elongated filtering fibers located within the interior of the housing and being attached to the support in a manner that a flow path extending between the first inlet and the first outlet passes through the filtering fibers intermediate the inlet and outlet, whereby the medium is filtered as it passes along the flow path through the fibers;
- and
- (d) alignment means for maintaining the orientation of the filtering fiber in a direction parallel to the flow path during the filtration process, whereby the tendency of the filtering fibers to compress against the support during the filtration process is minimized.

A filter for filtering a contaminated medium, comprising:
- (a) a hollow filter housing having an interior;
- (b) a first inlet located on the housing and communicating with the interior thereof, the first inlet having a plurality of nozzles, whereby a contaminated medium may be uniformly introduced into the interior of the housing through the nozzles and distributed evenly thereby;
- (c) a first outlet located on the housing and communicating with the interior thereof, the first outlet having a plurality of nozzles, whereby the medium may be uniformly withdrawn from the interior of the housing through the nozzles after the filtration process;
- (d) a support located within the interior of the housing;
- (e) a plurality of elongated filtering fibers located within the interior of the housing and being attached to the support in a manner that a flow path extending between the first inlet and the first outlet passes through the filtering fibers intermediate the inlet and outlet, whereby the medium is filtered as it passes along the flow path through the fibers;
- and
- (f) alignment means for maintaining the orientation of the filtering fibers in a direction parallel to the flow path during the filtration process, whereby the tendency of the filtering fibers to compress against the support during the filtration process is minimized.
