Sludge Treatment Sludge Screw Press Dewatering Muti Disc Screw
Press For Oily Sludge From Flotation
Process Introduction
- Sludge is first fed into the Flow Control Tank and then flows down
into the Flocculation Tank, where polymer coagulant is added
- From there, the flocculated sludge overflows into the dewatering
drum where it is filtered and compressed.The entire operation
sequence,including sludge feed control, polymer makeup, dosing and
sludge cake discharge are controlled by the built-in timer and
sensors of the PLC.
- Simple process, low system investment, highly efficient and
energy-saving dewatering.
- System can be programmed to make the operation more convenient and
accurate.
- Unique flocculating agent to make sludge dewatering easier.
- Uniform and accurate dispensing, saving running costs.

Application
suitable for low-concentration and high-concentration sludge
treatment, with a concentration from 2000mg/L-50000mg/L.
Working Process
1. Thickening: When the screw drive shaft rotates, the multiple
solid and active laminations arranged on the periphery of the drive
shaft move relative to each other. Under the action of gravity,
water is filtered out of the relatively moving lamination gap to
achieve rapid concentration.
2. Dewatering: The concentrated sludge moves forward with the
rotation of the screw shaft; along the direction of the mud cake
outlet, the pitch of the screw shaft gradually decreases, and the
gap between the rings gradually decreases, and the volume of the
spiral cavity Constantly shrinking; under the action of the back
pressure plate at the outlet, the internal pressure gradually
increases. Under the continuous continuous operation of the screw
drive shaft, the water in the sludge is squeezed and discharged,
and the solid content of the filter cake continues to increase,
finally achieving sludge Continuous dehydration.
3. Self-cleaning: The rotation of the screw shaft pushes the moving
ring to continuously rotate. The equipment relies on the movement
between the fixed ring and the moving ring to achieve a continuous
self-cleaning process, thereby cleverly avoiding the common
blocking problem of traditional dehydrators.
