<p>An apparatus which can be used for removing contaminants from a liquid and for coalescing droplets of a liquid dispersed in another immiscible liquid, which comprises a casing (1) divided into two compartments by a substantially tubular fibrous filter (2), formed by fibres attached at each end supports (3) and (4), there being a liquid inlet (8) leading to one side of the fibrous filter and a liquid outlet (9) leading from the other side of the fibrous filter, one of the end supports being connected to an actuating rod (6) which can move the end support axially and rotatably relative to the other end support, the fibrous filter being supported by a cage assembly (10) comprising a plurality of rings located within the fibrous filter preferably in the form of two sets of rings (11), (13) which can either be connected to the end supports or free to move independently. The structure enables more vigorous and effective back-washing.</p> |
