Liquid within the collection chamber defines a liquid level. The drum assembly defines a perforated cylindrical wall and the drum assembly is supported such that at least a portion of the drum assembly is below the liquid level. The drive assembly rotates the drum assembly, which has at least one screw flight within the drum member, relative to the housing. |
