Abstract
A whitewater system is provided for handling at high velocity the large quantities of water that are circulated in the high speed forming of pulp using a wire and forming wheel. Use of a centrifugal collector to transfer water from within a forming loop at velocities approaching that of wire speed permits the water to be partially deaerated automatically, so that return as white water to the pulping system is facilitated.
