Introducing the GNLW-654 Dewatering Decanter Centrifuge

The GNLW-654 is part of GN’s T-Series dewatering decanter centrifuges, built with a beach angle of 8.5 degrees.This design increases the length of the cone (beach) section, allowing more extended dewatering area and resulting in drier solid discharge.

Here are some of its key features and specifications:

 

Why the GNLW-654 is Ideal for Sludge Dewatering

 

This model is designedfor heavy-duty dewatering and thickening tasks. Among its advantages:

• Enhanced Dryness of Solids: The extended beach area and optimized internal geometry lead to better solids discharge dryness.

• Efficient Handling of Large & Dense Solids: It can process materials with large particle size, high density difference between solid and liquid, and high concentration.

• Durability & Materials: Key parts like the bowl and shaft caps are made from duplex stainless steel (e.g. SUS2205 or SUS2304) via centrifugal casting, improving corrosion resistance and avoiding issues common with welded structures.

• Wear-resistance: Solid discharge ports have hard tungsten carbide wear sleeves; screw blades are formed via CNC pressing for higher conveying efficiency and longer lifespan.

• Operational Flexibility & Monitoring: The machine is equipped with an advanced control panel (VFD, PLC, HMI), real-time monitoring of parameters like vibration, bearing temperature, motor current, etc., plus automatic alarm/protection systems.

Application & Benefits for the European Client

For our European partner, the GNLW-654 will be used to process sludge from municipal and industrial wastewater treatment. Key benefits include:

• Reduced disposal costs, thanks to much drier solids which are lighter and less bulky.

• Improved throughput, due to higher processing capacity and better separation of solids & liquids.

• Lower energy usage, as optimized design minimizes turbulence and mechanical losses.

• Reduced maintenance downtime, thanks to wear-resistant parts and ease of component removal (e.g. hydraulic disassembly of main bearing).

GN Separation is pleased to announce the completion and delivery of our new Material Separation Testing Workshop, designed to support clients in evaluating equipment performance and selecting the most suitable solution for their applications. This dedicated facility integrates multiple testing modules, enabling both customer material testing at GN and on-site testing at customer facilities.

Comprehensive Testing Modules

The new workshop is equipped with five specialized testing modules:

1. Mining Vibrating Screen Testing Module – Simulates real mine conditions to verify screening efficiency for ores, tailings, and other mining materials.

2. Drilling Vibrating Screen Testing Module – Focuses on the separation of drilling fluids and solids to ensure stable performance in oil & gas operations.

3. Decanter Centrifuge Testing Module – Designed to test GN’s series of decanter centrifuges under different material conditions. Clients can confirm separation results such as moisture content, clarity of recovered liquid, and throughput capacity.

4. Combined Separation Testing Module (Vibrating Screen + Decanter Centrifuge) – Allows testing of integrated separation processes where a vibrating screen handles coarse solids removal, followed by a centrifuge for fine particle separation. This module replicates real-world solid-liquid separation flows for industries such as mining, drilling, and wastewater treatment.

5. Solid Vacuum Pump Testing Module – Provides verification of pneumatic material transfer for slurries, sludge, and high-solid-content materials.

Highlight: Decanter Centrifuge Testing

Among these, the Decanter Centrifuge Testing Module is a core component. GN Separation’s decanter centrifuges are widely used in industries such as mining, oil & gas, wastewater treatment, and chemical processing.

Our centrifuges are designed for continuous solid-liquid separation with high efficiency. Featuring robust construction, wear-resistant materials, and optimized bowl and screw designs, they deliver reliable performance even under demanding conditions.

• Versatility: Suitable for a wide range of slurries and sludge.

• Separation Performance: High clarity of liquid discharge and low moisture content in solids.

• Process Adaptability: Available in two-phase or three-phase models to suit different applications.

Customer-Oriented Testing Service

With this new workshop, GN Separation can now:

• Receive customer-supplied materials for in-house testing and issue performance reports.

• Arrange field testing at customer sites, ensuring accurate evaluation under actual working conditions.

This flexible testing capability enables clients to confirm separation efficiency, capacity, and reliability before finalizing equipment selection, minimizing risks and ensuring the right match for their process requirements.
