A disposable filter comprises a bundle of hollow fibres arranged in a housing having an inlet for a particle-laden volume of liquid to be filtered, as well as an outlet or a collecting chamber for the permeate. The inlet communicates with the interior of the hollow fibres, and the outlet or collecting chamber communicates with the exterior thereof. Before the filter is used, the moisture content of the hollow fibres is below 0.1 %, preferably below 0.05 %. In a separation method for removing particles from a particle-laden volume of liquid by means of such a filter, a pressure difference is generated between the interior and the exterior of the hollow fibres when the liquid is supplied to the filter, thus increasing the yield of permeate and reducing the filtering time. The total area of the hollow fibres is dimensioned such that a major part of the maximum permeate volume available can be obtained when the liquid flows once along the entire length of the hollow fibres, so that the filter can be discarded after a single use. |
