ABSTRACT A horizontal, Fourdrinier foraminous belt type, countercurrent, high-capacity, cellulose pulp washer is described. The described washer is equipped with a hood positioned over a portion of the belt and over vacuum boxes or receptacles under the upper loop of the belt. The gases and vapors drawn into the vacuum boxes or receptacles with the wash liquid are separated from the liquid in the receptacles and recycled to the hood to control the atmosphere in the hood and maintain the desired pressure differential for operation of the washer.
