SFC Dewatering Screw press Machine and manual screw press on
As a professional DL Sludge dehydrator multi-disc screw press
manufacturer, we keep introducing the best technology and forward
their localization in China. Thus compared to other Chinese , we
can offer the sludge machine of best cost performance.
MDS Sludge dehydrator multi-disc screw press is our typical sludge
developed by based on Japanese technology , which brought
epoch-making innovations to sludge dewatering technology.
The performance of DL Sludge dehydrator multi-disc screw press is
enhanced by removing clogging which could considerably block the
discharge of the filtered liquid.
The dimensions and other information of SFC Polymer preparation
unit are as follows:
|Inlet Consistency(SS 0.4-3.5%)||0.1-1.25||0.2-2.5||0.45-3.75||0.9-7.5||1.4-12.5||2.8-25||4.2-37.5||4-37.5||8-75|

Volute is structured with a filter element that consist of two
types of rings :a fixed ring and moving ring ; and a screw that
thrusts the filter element and transfers and pressurizes the
sludge. The gaps between the Rings and the screw pitch thrust the
filter element and transfers and pressurizes the sludge. The gaps
between the rings and the screw pitch are designed to gradually get
narrower towards the direction of sludge cake outlet and the inner
pressure of the element increase due to the volume compression
effect ,which thickens and dewaters the sludge.
Screw Press could be used in the treatment of industrial
wastewater, surface water, reused water and Municipal Wastewater
Treatment Plant .
SFC provides total solution for Screw Press and the whole process
1. Survey. Confirm estimate dosing capacity and material of the
2. Proper capacity.model and auxiliary equipments.
3. Design.Standardizing design .
4. ISO9001 . Production and fabrication
1. Sludge in the sludge storage tank flows into the flow control
tank through the sludge feed pump.
2. Sludge sent into the flow control tank is measured by a flow
meter - gage. The measured sludge is sent to the flocculation tank
and the excessive amount flows back into the overflow pipe and
returns back (water - level adjuster).
3. Polymer is added to sludge in the flocculation tank through the
polymer feed pump .
4. Sludge flows into the cylinder unit after flocks are being
formed by polymer reaction between sludge
and polymer using the force of flocculation tank agitator .
5. The flocks are thickened in the thickening zone by gravitation
force before flowing into the dewatering zone.
6. The gaps between moving rings and fixed rings are smaller in the
dewatering zone than in the thickening zone ,and the sludge turus
into sludge cake by the pressure provided by the end plate and is
