[origin: US2002112837A1] In a method and an associated apparatus for discharging the whitewater from inside the loop of a continuous dewatering wire of a former, specifically a twin wire former in a paper machine the accumulating whitewater is collected by a collection tank, which is located within the loop; the collected whitewater is separated from the air, still inside the loop, by suctioning off of the area above the collection tank and the whitewater is removed from the collection tank through at least one channel that is connected to the collection tank and is located below the collection tank's water level.
