Abstract: A method of filtrating liquid, the method comprising conducting a liquid through a filtering element, through an outlet line downstream of the filtering element and to a collection volume downstream of the outlet line; controlling a differential pressure of the liquid over the filtering element; and controlling a passing time of a filter flow of the liquid through the filtering element in conjunction with the differential pressure; wherein the control of the differential pressure and the passing time comprises controlling a collection volume liquid flow of the liquid out from the collection volume; and controlling a gas flow out from the collection volume. A filtration apparatus for filtrating liquid is also provided.

Abstract: A filtration arrangement for a filtration apparatus for filtrating liquid, the filtration arrangement comprising a filtration vessel; a continuous filtering element for removing particles from liquid passing therethrough, the filtering element being arranged to move along a path into the filtration vessel and out from the filtration vessel; and two wheels sealingly engaging the filtering element on opposite sides thereof inside the filtration vessel, where each of the two wheels is rotatable relative to the filtration vessel along with movement of the filtering element. A filtration arrangement comprising a fluid ejecting device, and a filtration apparatus are also provided.
