Abstract
Devices, systems, and methods are disclosed to separate solids from liquids. A vessel includes a screw, an inlet, a first outlet, and a second outlet. The inlet receives a first slurry having an incoming solids concentration. The first slurry consists of solids and a contact liquid. The first outlet is disposed toward the first end of the vessel. The second outlet is disposed toward a second end of the vessel. The screw preferentially conveys the solids over the contact liquid towards the second end of the vessel, the solids displacing at least a portion of the contact liquid, causing that portion of the contact liquid to flow toward the first outlet. A melting device is included.
