ABSTRACT:
An apparatus providing process water used for making or processing a fiber suspension includes a multi-compartment tank with a top, a bottom wall, and a plurality of exterior sidewalls. Each compartment has an inlet positioned near the top, an outlet positioned near the bottom wall, and at least one intervening wall common with an adjacent compartment. Each intervening wall has a height defining an overflow weir whereby the compartments are arranged with sequentially decreasing maximum fluid levels. Each intervening wall also has a backflow device positioned near the bottom wall. The backflow device is selectively openable to allow flow from one compartment to an adjacent compartment in a direction opposite to a flow direction over the corresponding overflow weir.
