Separator Solid-liquid Separation Sludge Dewatering Machine Wastewater Treatment Plant Environmental Compliance

Fixed Rings & Moving Rings
Stacked alternately to form a filterchamber; tiny gaps between the ringstrap sludge flocs while
enabling smoothwater drainage.

Screw Shaft
Provides forward propulsion for sludge,qenerates stronq extrusion force viapitch and shaft variations,
and drivessludge from the thickening section tothe dewatering section.

Plc panelintelligent automatic control system 
Automatically adjusts chemical dosing, aeration time, and sludge return ratio based oninfluent
quality to prevent manual errors.




Based on the sludge flow and concentration detected,the automatic dosingsystem adjusts in real-time to
ensure the optimal dosage ratio, resulting in stabledewatering performance and consistently high-quality
sludge cake.



100%o premiumRaw materials
Crafted from stainless steel, it resists corrosion and rust. Fixed and movable rings are stacked alternately,
with a multi-layer screw shaft running through the entire set of rings.


One-touch operationfor full automation.
One-touch start/stop, auto-cleaning,and fault alerts. Syncs with theauto-dosing svstem to adjustchemical
feed based on sludge flowand concentration, ensuring peakefficiency and minimal chemical use.


Core ComponentsPowered by leadingInternational brands
Featuring Siemens, Grundfos,Schneider, ABB, and NORD corecomponents - ensuring 40%lower maintenance
costs withhigh-efficiency operation.

Working Process
Flocculation Pretreatment: Sludge mixes with flocculant to form dense flocs.
Thickening & Screw Press Dewatering: Flocculated sludge enters the main unit.Free water is gravity-filtered in
the thickening section; then in the dewatering sec-tion, the screw shaft's variable pitch and diameter create
increasing extrusionforce. Together with back pressure plate resistance, capillary water is squeezedout, forming
low-moisture sludge cake.
Self-cleaning & Anti-clogging: Moving rings rotate with the screw shaft, rubbingagainst fixed rings to automatically
clear inter-ring sludge and ensure stable con-tinuous operation.

Product features
Continuous automatic operation, enabling 24/7 fully automated processes from feed-ing to dewatering, discharge
and cleaning without manual intervention, significantlyreducing labor costs.Strong anti-clogging and self-cleaning
capabilities-minimal movement between ringsduring operation automatically removes accumulated sludge
fundamentally preventingblockages.
Low-speed operation ensures minimal energy consumption, reduced wear, extendedequipment service life, and
low maintenance costs.
