Dewatering Screws

SEPFIL's dewatering screw is a simple machine to dewater sand, grit and other matter that can be settled. The working principle is based on a settle tank and a screw elevator. The elevator transports the waste matter upwards which dewaters the solids to be removed.

The residue will be upwards transported through the screw. Above the water level, the water stream goes backwards, through which the waste can be transported. The design of the inlet part reduces turbulence till a minimum. Because of this a calm flow patron arises. This is necessary for an optimal waste. The axisfree screw can be driven continuous as discontinues.
