Abstract
An arrangement for handling white water from a paper machine comprises a white water channel having an inlet end for receiving white water from a paper machine and an opposite outlet end defining a main outlet through which the white water is discharged into a container. A channel bottom slopes downward and an additional outlet is provided between the main outlet and the inlet end, the bottom having a first bottom portion that leads away from the inlet end up to the additional outlet and a second bottom portion that leads away from the additional outlet toward the main outlet. The first and second bottom portions are so arranged in relation to each other that each of the bottom portions slopes downward in the flow direction at an angle of inclination that exceeds a critical angle of inclination that avoids sedimentation on the bottom.
