Abstract
Abstract A filter coalescer cartridge for removing contaminants from a liquid comprises: (a) a first support at one end of the cartridge, (b) a second end support tending towards the other end of the cartridge, (c) a filter coalescer element comprising a plurality of aligned fibres or bundles of fibres, each fibre or bundle being secured at one end to one end support and at the other end to the other end support, and (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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
121 words
A filter coalescer cartridge (2) for removing contaminants from a liquid which cartridge comprises: (a) first end support (10) at one end of the cartridge (2), (b) a second end support (11) tending towards the other end of the cartridge, (c) a filter coalescer element (15) comprising a plurality of aligned fibres or bundles of fibres (18), each fibre or bundle being secured at one end to one end support and at the other end to the other end support,characterised by the fact that the cartridge comprises (d) a drive mechanism (13, 13a) 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 (15).
