MULTI-DISK type screw

- Dehydrator is designed so that sludge entering through the inlet moves at a constant speed through a screw that has a decreasing pitch and dehydrated by a filtration part whit decreasing distance.

- This type of structure maintains a certain gap between the exterior of the screw and the interior of the ring which prevents wear and tear of the screw and the ring. Additionally due to left and right rotation of the moving ring, foreign substances in the gap can be permanently removed.
