The stacked screw dehydrator adopts a multi-disc type to separate and dewater the sludge and realize the recovery of solids. Let’s take a look at the advantages of the stacked screw dehydrator together.


1. Can handle oily sludge
With an offline structure, it is not easy to cause clogging and can handle oily sludge.
2. Energy saving
Structure and miniaturization design, according to the “gravity filtration and extrusion” dehydration principle, adopts energy-saving structure and miniaturization design, making installation very simple;
3. The stacked screw dehydrator only needs a small amount of clean water
Because its filter structure is not easy to cause mesh clogging, it should be cleaned every 1-3 hours, and the time is about 7 minutes. Compared with filter cloth dehydrator, this machine has better water saving effect;
4. Suitable for treating oily, low-concentration sludge
Since its structure will not be blocked, it is suitable for the treatment of oily sludge containing oily flocs in food factories;
Moreover, since it has a thickening zone and a dewatering zone, in addition to thickening the sludge, it can also handle low-concentration sludge (about 0.3%) that is difficult for conventional dehydrators to handle.
5. Can run continuously and automatically
It is easy to operate and can be operated automatically. At the same time, it can choose to use a polymer flocculant (liquid product) dissolving device for unattended continuous operation.
6. Screw dehydrator prevents secondary pollution
The main engine is a semi-sealed structure, the filter element has a low speed, no sludge is scattered, and the noise, vibration and odor diffusion are also very limited. Routine maintenance is simple and easy.
7. The stacked screw dehydrator is convenient and quick to clean
Since this structure does not cause clogging, it does not perform recovery cleaning due to capacity reduction, and only the sludge seeping out from the dehydration part can be cleaned.
The above is the relevant introduction about the stacking screw dehydrator, I hope it will be helpful to everyone.
