Basically you'd need the equivalent of a drill bit in a sleeve. Think of a drill bit boring a hole. The shavings climb up the flutes of the bit and out of the hole. A sleeve around a spirally fluted shaft may do the trick. Make the screw turn in conjunction with the turbine and make the sleeve stationary; much like an extruder for plastics. This will also create some heat increase due to friction of the water between the sleeve and screw creating an increase in pressure as it runs.
