GN Nodig Mud Recycling System

GN Separation recently delivered its GNLW364 T Series Dewatering Decanter Centrifuge to an overseas environmental protection company, further expanding its global footprint in industrial and municipal sludge treatment. Known for its efficient performance and robust design, the GNLW364 centrifuge is ideally suited for high-demand dewatering applications across various industries.

Optimized for Dewatering Performance

The GNLW364 model belongs to GN’s T Series, a line of decanter centrifuges specifically engineered for dewatering and thickening purposes. Featuring an optimized beach angle of 8.5 degrees, the T Series is designed to extend the drying zone within the bowl, allowing for higher solid dryness and clearer liquid separation.

This series is widely applied for municipal and industrial wastewater sludge, where efficient dewatering and reduced moisture content are critical. For materials containing fine particles and low viscosity, flocculants are typically added to enhance solid-liquid separation performance before processing through the T Series decanter.

Key Features of the GNLW364 T Series Decanter Centrifuge

• Bowl Diameter: 360 mm

• Bowl Length: 1520 mm

• Max Speed: 3964 RPM

• Max G-force: 3200 G

• Main Motor Power: 22–37 kW

• Backdrive Motor Power: 7.5–11 kW

• Beach Angle: 8.5°

Intelligent and Safe Operation

This unit is equipped with a three-frequency conversion control cabinet — a smart electrical system that allows for independent control of the main motor, backdrive motor, and feed pump. Combined with real-time monitoring sensors for temperature and vibration, the system ensures safe, stable, and efficient operation, even under demanding conditions.

GN also integrates a complete alarm and protection system. If abnormal parameters such as overload, high temperature, or excessive vibration are detected, the machine automatically initiates safety protocols, including switching to plug removal or emergency shutdown procedures.

Durable Materials and High-Quality Construction

To guarantee longevity and performance, the bowl and end caps are made from duplex stainless steel (SUS2205 or SUS2304) via centrifugal casting, which provides superior resistance to corrosion and stress compared to conventional stainless steel grades like SUS304 or SUS316.

The screw conveyor is protected by replaceable tungsten carbide tiles, and the discharge ports are reinforced with wear-resistant tungsten carbide sleeves, significantly extending the service life of these high-wear components.

Compact and Service-Friendly Design

The GNLW364 adopts a compact layout, with both motors positioned at one end of the machine. This design not only saves space but also simplifies maintenance. GN’s decanters are also engineered for easy disassembly, and for larger models, hydraulic bearing removal systems are available to reduce the risk of component damage during maintenance.

Trusted by Global Environmental Companies

The overseas environmental firm selected the GNLW364 after rigorous evaluation due to its high dewatering performance, intelligent control system, and low maintenance requirements. With its reliable performance and energy-efficient operation, the GNLW364 is now playing a key role in helping the company meet strict environmental discharge standards and reduce waste handling costs.

Sugar beet processing involves extensive washing to remove soil and impurities, resulting in wastewater rich in suspended solids. Traditional treatment methods often struggle with the high solids content and the need for continuous operation, leading to increased maintenance and operational costs.

The Solution: GN Separation’s GNLW764 Decanter Centrifuges

To tackle these challenges, a European sugar processing facility integrated three units of GN Separation’s GNLW764 decanter centrifuges into their wastewater treatment line. These centrifuges are specifically designed for high-capacity, continuous operation, making them ideal for the demanding conditions of sugar beet processing.

Key Features and Advantages:

• Large Processing Capacity: Each GNLW764 unit features a 30-inch (760 mm) bowl diameter and a bowl length of 131 inches (3328 mm), enabling it to handle substantial volumes of wastewater efficiently. Scribd+6gnseparation.com+6gnseparation.com+6

• High G-Force Separation: Operating at a maximum bowl speed of 2612 RPM, the centrifuge generates up to 2900 G, facilitating the effective separation of fine solids from the liquid phase. gnseparation.com+3gnseparation.com+3GN Separation+3

• Durable Construction: The bowl and screw are constructed from duplex stainless steel (SUS2304/SUS2205), ensuring resistance to corrosion and wear, which is crucial for processing abrasive materials found in sugar beet wash water. gnseparation.com+3GN Separation+3gnseparation.com+3

• Automated Operation: Equipped with a VFD+PLC+HMI control system, the centrifuge allows for precise control over operational parameters, reducing the need for manual intervention and minimizing downtime. gnseparation.com+5gnseparation.com+5GN Separation+5

Impact on Sugar Beet Processing:

The implementation of GN Separation’s GNLW764 decanter centrifuges has significantly improved the efficiency of wastewater treatment in the sugar processing facility. The centrifuges effectively reduce the moisture content of the discharged solids, facilitating easier handling and disposal. Moreover, the clarified water can be recycled back into the process, promoting sustainable water management practices.

Conclusion:

GN Separation’s GNLW764 decanter centrifuges offer a reliable and efficient solution for managing the complex wastewater challenges in sugar beet processing. Their high-capacity design, robust construction, and automated operation make them an invaluable asset for sugar plants aiming to enhance their wastewater treatment processes and achieve greater operational sustainability.

GN Separation is proud to announce the successful delivery of our Dewatering Centrifuge System to an overseas client. This system includes our high-performance GNLW series Decanter Centrifuge and the GNSJY2000 Chemical Dosing Unit, designed to meet the demanding requirements of wastewater treatment and sludge dewatering applications.

GN Dewatering System: Effective Solution for Fine Particle Separation

In many wastewater treatment processes, simple mechanical separation methods can only remove particles in the range of 2–5 microns. However, ultrafine particles, often present in industrial wastewater, are much more difficult to remove using traditional methods.

GN’s Dewatering System provides an efficient solution by combining a high-speed Decanter Centrifuge with a Chemical Dosing Unit. With this integrated system, ultrafine particles can be flocculated into larger, more easily separable clusters, enabling the centrifuge to achieve optimal separation performance and meet the client’s discharge or reuse requirements.

GNSJY2000 Chemical Dosing Unit: Precision and Efficiency

The GN Chemical Dosing Unit is a compact, easy-to-operate, and low-energy consumption system designed for the automatic preparation and dosing of flocculants. It is widely used in sludge dewatering, solid-liquid separation, and various water treatment processes. The dosing compartment allows for stirring, dissolving, and storage of flocculants, which are then delivered to each dosing point by dosing pumps.

To meet various project needs, GN Separation offers two standard types of Chemical Dosing Units:
