    摘要: The invention relates to apparatus (1) for filtering a fluid having a body (2) and a filter medium (3) comprising a mass of compressible fibres which is compressed by a device (4) which in the embodiment is an inflatable rubber diaphragm. There is an inlet (11) for liquid to be filtered and an outlet (18) for filtrate, the liquid passing through a perforated plate (8) to the medium (3). The filter medium is backwashed by expanding the medium (3) by relaxing the device (4) as by deflating it and passing liquid through the outlet (18) through the media and hence to the inlet (11).
