A screw conveyor is essentially an enclosed auger. The leading edge of the screw grabs some solids and pushes them up the inside of the tube. Any liquid caught in the process drains back down the slope between the screw and the tube wall. Of course, any liquid saturated into your solids will be along for the ride, but the majority of your free liquid should be returned to the tank via gravity.

Archimedes' Wheel.

If the screw fills the pipe, it will not flow back down.

Water seeks it's own level.

If you want to drain off the liquids you could make the screw/auger chute/pipe from perforated steel.

You should also use a tapering screw so that the volume gets smaller with distance. This will squeeze the liquid out of the solids.
