Abstract

A method and system for control of flows of in a pulp mill, comprising storing pulp from fiberline in a first pulp tower (10); directing the pulp from the first pulp tower (10) to pulp drying; storing white water from the pulp drying into a first water tower (30) and directing the water therefrom back to the fiberline; and when the fiberline is not able to receive the white water from the first water tower (30), directing the white water to second pulp tower (10) comprising pulp with such consistency that the white water and the pulp remain substantially separated in different layers in the second pulp tower (20).
