Bag dewatering
Bag dewatering for the ATS 2200
Bag dewatering reroutes the flow of water into the suction end of the pump. Water is pulled from around
the outside of the bulk bag instead of pulling from the top of the cross-flow separator as it does in Cross-
flow mode. This creates a vacuum outside of the bag, which pulls water through the bag membrane.
Water is also removed from the void between the bag frame and the outer chamber wall, and clean
water is returned to the catcher tank.
For ATS 2200 bag dewatering , do the following:
1. While the machine is in operation, remove the suction and discharge hoses from below the
water level, but leave them over the catcher tank to remove any excess water from the cross-
flow separator. After several seconds, the discharge hose will stop discharging water. Once
this occurs, it's okay to raise the lid on the VacBOX to continue manual dewatering.
2. Purge excess water from the machine before you remove the bulk bag. To remove the water
and silt surrounding the bag, rotate the ball valve handle until it is perpendicular to the pump
suction manifold, and then restart the machine.
◦ Lid can be in either the open or closed position for this step.
