In a method of filtering particle-contaminated liquid delivered to the upper side of a filter which coacts with an outlet, spray pipes equipped with nozzles and rotatably mounted beneath the underside of the filter direct jets of flushing liquid onto the filter. Mounted above the filter surface at a distance therefrom is a drainage channel by means of which parts of the particle-carrying liquid is collected and conducted to the outlet. The drainage channel has an extended part which forms a channel inlet and also functions as a splash guard. The invention also relates to a filter arrangement of the kind defined.
