Abstract (en)
[origin: WO0012811A1] A method of separating a fiber fraction by screening from a liquid containing fibers and small particles, where the separation takes place in that the ingoing liquid is allowed to flow along a screen member with screen apertures from an inlet (2) to a first outlet (3) for a first fraction which passes through the screen apertures, and a second outlet (4) for a second fraction, which does not pass through the screen apertures. 50-80 % of the flow of the second fraction is recycled from the second outlet (4) to the inlet (2) for increasing the concentration of network forming fibers in the ingoing liquid.
