Screw sludge dehydrator is the innovative layered multi-disk sludge
dewatering press. It is
able to treat low concentration sludg and oily sludge effectively,
with low energy consumption
and easy operation, realizing an energy .
Screw dewatering press is mainly used in wastewater treatment
industries, such as:
1. Municipal water and wastewater treatment plants
2. Agricultural/fishery community wastewater treatment plants
3. Industrial waste treatment plants
4. Food/beverage production plants
5. Dairy farming/Meat processing plants
6. Chemicals manufacturing plants
7. Machinery manufacturing/Metal processing plants
8. Laundry wastewater
9. Especially for the sludge with high oil content
Advantage
1) Without secondary pollution
The screw shaft rotational speed about 2-3r/min, no vibration and
noise is very small ; The
laminated with self - cleaning function, plugging does not occur,
only a small amount of water
washing, without secondary pollution, and sludge at such a slow
running under the operating
condition, the smell does not spread, thereby creating a great work
environment!
2) Contactless, Wear Free Structure Design
Volute sludge dewatering uses the contactless wear free structure
between the disks and
screw shafts, thus the service life of the Screw shafts and the
rings will be greatly extended.
The treatment capacity of equipment and processing effects can be
improved in combination
with other optimization design.
3) Decrease Capital Investment
Volute sludge dewatering can treat sludge in aeration tank and
secondary sedimentation tank
without setting sludge thickeners. Therefore, this can decrease the
total investment, avoid
phosphorus release from the sludge thickeners and sludge storage
tanks and enhance
phosphorus removal effect of the wastewater treatment system.
4) High Resistance to Oily Sludge
The self-cleaning mechanism and stainless steel structure enables
MDS to be ideal to
dewater oily sludge, which easily causes clogging and is difficult
to treat with other types of
dewatering equipment.
