ABSTRACT:
A cartridge (7) for removing contaminants from a liquid comprises (a) a central inlet or outlet, (b) a circumferential outlet or inlet for radial flow through the cartridge and (c) a resilient, helically coiled plate (8) permeable to liquid. One edge of the plate is secured at or near the central inlet or outlet, the other edge is secured at or near the circumferential outlet or inlet and means is provided for tensioning the plate.
The cartridge may be used in a filter.
It may be modified by adding a fibrous layer to the coiled plate. This renders it suitable for use as a coalescer.
