ABSTRACT:
In the representative liquid removal system described in the specification, a suspension of solid particles in a liquid received, for example, from a gravity separator, is directed to a tank having an upwardly inclined moving screen forming one wall and gas bubbles or gas-saturated liquid are injected into the suspension at the inlet. As a result, the liquid removed through the screen in the lower portion of the tank carries fewer solid particles onto the screen, preventing the screen from becoming blocked and thereby inhibiting liquid removal.
