A method of filtering a fluid in a filter system including a filter (6) comprises modifying the filter throughput during filtration in such a way that the differential pressure across the filter (6) caused by the build-up of filter cake in the filter is substantially maintained at a predetermined level for at least part of the filter-operation time between flushings. A filter system for operating the method comprises a filter (6), a sensor ( DELTA rho ) for detecting the differential pressure across the filter during filtration, and a valve (8) for modifying the filter throughput according to the differential pressure. |
