At GN Separation, our mission is to deliver high-performance, reliable, and sustainable solutions for solid–liquid separation. Two flagship pieces of equipment that illustrate this are the GNLW364 sludge dewatering centrifuge and the GNSJY3000 chemical dosing unit. Recently, we successfully deployed these systems in overseas sludge dewatering projects—here’s how they work together to deliver superior results.
GNLW364 Sludge Dewatering Centrifuge
The GNLW364 is a 14-inch bowl, high-speed decanter centrifuge engineered specifically for wastewater and sludge dewatering applications. Some of its key features:
-
Robust Drive System & Control Cabinet: Equipped with a dual-motor drive and a three-frequency conversion control cabinet that allows independent control over the main motor, back drive motor, and feed pump. This ensures optimal performance to match the characteristics of the sludge.
-
Wear Resistance & Materials: Critical parts such as the screw conveyor and discharge ports are protected with tungsten carbide inserts. The bowl assembly is made from duplex stainless steel for both strength and corrosion resistance.
-
Safety & Monitoring: Real-time vibration and temperature sensors, along with PLC-based overload protection, provide continuous and safe operation.
-
Separation Efficiency: The centrifuge is designed for high solids loading and delivers excellent dryness of discharged solids, suitable for municipal and industrial sludge applications.
GNSJY3000 Chemical Dosing Unit
To enhance the performance of the centrifuge, particularly when dealing with ultra-fine solids, GN Separation offers the GNSJY3000 chemical dosing unit. Key aspects include:
-
Purpose & Function: Used to flocculate fine particles that cannot be efficiently removed by centrifugation alone, thereby improving separation and effluent clarity.
-
Flexible Configuration: Designed to handle either liquid or powdered chemicals, with optional configurations for different operating environments.
-
Capacity & Operation: The dosing capacity can be adjusted according to the sludge characteristics and centrifuge throughput. Clients can choose the system configuration based on required dosing rates and safety needs.
-
Integration: The dosing unit works seamlessly with the centrifuge, enabling automated or semi-automated control of chemical addition, leading to more stable operation and reduced chemical consumption.
Combined Workflow: GNLW364 + GNSJY3000 in Sludge Dewatering Projects
-
Feed Conditioning: Sludge is analyzed for solids content and particle size. If fine particles are present, the dosing unit is engaged to condition the sludge.
-
Chemical Dosing: Coagulants or flocculants are precisely added through the GNSJY3000 to enhance separation.
-
Centrifugation: The conditioned sludge is processed by the GNLW364, which captures solids and discharges clarified liquid.
-
Outcome: Higher dryness of solids, cleaner effluent, reduced transport costs, and improved overall efficiency.
Why Choose GN Separation
-
Customization: Equipment can be tailored to specific feed conditions and project requirements.
-
Durability: Premium materials and wear-resistant protections ensure long service life.
-
Proven Success: The GNLW364 centrifuge and GNSJY3000 dosing unit have already been applied in overseas sludge dewatering projects with reliable results.
If you are considering a sludge dewatering project and require stable performance, high efficiency, and cost-effective operation, GN Separation’s GNLW364 centrifuge combined with the GNSJY3000 chemical dosing unit is the right choice.
