Recently, GN Separation successfully assembled and shipped a complete sludge dewatering system for an international client in the environmental engineering sector. The package consists of the core GNLW364 decanter centrifuge and a complementary 3000L Automatic Polymer Dosing Unit (Model GNSJY3000). 
Key Features of the GNLW364 Dewatering Centrifuge
The GNLW364 decanter centrifuge is designed to maximize sludge dewatering efficiency in both industrial and municipal applications.
High-Speed Separation & Throughput
Variable-frequency drive (VFD) enables speeds up to 3,900 RPM, generating forces over 3,000 G.
Rapid solid–liquid separation reduces sludge moisture content, depending on feed conditions.
A 360 mm bowl diameter and 1,420 mm length provide ample sedimentation area, boosting capacity.
Robust Construction & Longevity
Bowl and scroll conveyor are centrifugally cast from duplex stainless steel (2205) for superior corrosion resistance.
Wear-prone components—such as the slurry feed port, scroll blades, and solids discharge—are protected with tungsten carbide plates or bushings, extending service life.
Compact design simplifies integration into existing facilities.
Automation & Safety
PLC-based controls monitor vibration, temperature, and torque in real time.
Automatic shutdown protocols protect against overload or imbalance.
An integrated back-drive system allows manual bowl rotation for safer maintenance.
Polymer Dosing Unit (GNSJY3000): Essential for Performance
Efficient dewatering depends on both mechanical separation and chemical conditioning. The GNSJY3000 ensures optimal polymer activation through a fully automated three-stage process: dry feeding, wetting, and aging.
Vertical tank design reduces sedimentation risks.
Built-in stirrer maintains consistent polymer quality.
Low energy consumption makes it suitable for continuous operation.
Integrated System Benefits
Together, the GNLW364 decanter centrifuge and GNSJY3000 dosing unit deliver measurable advantages:
Reduced chemical use: precise dosing lowers polymer consumption and operating costs.
Improved cake dryness: well-conditioned sludge produces denser cakes, cutting disposal volume and fees.
Lower power demand: VFD-controlled centrifuge adapts to feed rates, while efficient mixing reduces waste.
Regulatory compliance: higher dryness levels support stricter discharge standards and water reuse initiatives.
Expanding Global Presence
This delivery highlights GN Separation’s continued expansion into international markets, particularly in regions facing rapid urbanization and growing waste management needs. By combining durable equipment with intelligent automation, GN provides clients with scalable, low-maintenance solutions that drive both economic and environmental benefits.
