Abstract
This invention relates to apparatus for removing contaminants from a liquid. The contaminants may be solid particles and/or a second liquid immiscible with but finely dispersed in the first liquid. More particularly, the invention relates to a filter coalescer cartridge for removing contaminants from a liquid which comprises: PA1 (a) a first support at one end of the cartridge, PA1 (b) a second end support tending towards the other end of the cartridge, PA1 (c) a filter coalescer element comprising a plurality of aligned fibers or bundles of fibers, each fiber or bundle being secured at one end to one end support and at the other end to the other end support, and PA1 (d) a drive mechanism for relatively rotating and moving the end supports towards and away from each other to twist and compress and straighten and extend respectively the filter coalescer element. The cartridge gives good performance and is easily regenerated.
