The disclosure relates to a method and apparatus for removing separable impurities from a liquid. In the method, the liquid is caused to pass radially through a cylindrical roll of web-like, wet-strength fiber material at the same time as the fiber web which forms the roll is continuously drawn out at low speed from the roll at that circumferential side where the liquid is caused to enter. As a result, the roll constantly offers a relatively clean surface to the penetrating liquid. The apparatus comprises a chamber for the roll, a conduit for conducting the liquid to the one circumferential side of the roll, a discharge for conveying off liquid from the vessel at the other side of the roll, rollers for guided withdrawal of the fiber web, and a receptacle for collecting the web withdrawn from the roll.
