GN 3 Phase Decanter Centrifuge for USA Oil Sludge Treatment Project

GN Separation has recently completed the assembly of its GNLWS554 3-phase decanter centrifuge, which is now ready for shipment to the United States. The system will be deployed for the treatment of oily sludge—an industrial byproduct that poses significant environmental and operational challenges.

The Role of Three-Phase Decanter Centrifuges in oil sludge treatment

Oily sludge, generated during oil extraction, refining, and storage, contains a complex mixture of oil, water, and solids. Traditional treatment methods often fall short in achieving effective separation, resulting in high disposal costs and environmental compliance risks.

GN’s 3-phase decanter centrifuge provides a reliable, one-step solution to efficiently separate oil, water, and solids. Utilizing high-speed centrifugal force, the GNLWS554 accelerates the gravitational separation process, enabling oil recovery and significant reduction in waste volume.

Designed to perform in harsh industrial conditions, the GNLWS554 offers enhanced separation efficiency and robust operational reliability, making it an ideal alternative to conventional treatment systems.

Key Features of the GNLWS554 3-phase decanter centrifuge

  1. Dual-Motor Drive with VFD Precision Control
    The GNLWS554 features a dual-motor design with independent VFD control for both bowl and scroll. This allows operators to precisely adjust the differential speed for optimal separation across varying feed conditions.
  2. Tungsten Carbide Wear Protection
    To withstand the abrasive characteristics of oily sludge, all critical components—such as scroll flights and discharge ports—are protected with tungsten carbide tiles and sleeves. This significantly extends service life and reduces maintenance costs.
  3. Adjustable Centripetal Pump System
    The built-in centripetal pump allows for on-the-fly adjustment of the liquid phase interface. Operators can easily control the separation boundary between the oil and water phases, providing flexibility for different feed compositions and compliance standards.

Wide-Ranging Applications Across Industries

In addition to oily sludge treatment, GN’s three-phase decanter centrifuges are widely used in various sectors:

Food & Beverage: Fat and solid separation in dairy, edible oil, and starch processing

Chemical & Pharmaceutical: Recovery of catalysts, purification of emulsions, and byproduct separation

Municipal Wastewater: Grease and sludge separation in sewage treatment plants

Mining & Minerals: Dewatering tailings and recovering minerals from slurry

The GNLWS554’s performance-proven design—featuring a dual-motor drive, wear-resistant materials, and real-time interface control—ensures stable, high-efficiency operation in all these demanding environments.

As industries face growing regulatory pressures and rising treatment costs, GN Separation’s three-phase decanter centrifuge provides a sustainable, cost-effective solution for sludge and waste management.

The Development Prospect of Decanter Centrifuge Manufacturers

The decanter centrifuge, a type of mechanical separation equipment, has a long history of application dating back to the early 18th century. Initially used in chemical production, it has since found wide adoption across various sectors including pharmaceuticals, metallurgy, dyes, food processing, brewing, ceramics, and environmental protection. Today, despite its long-standing use, much of the industry still relies on intermittent operation modes. However, as industrial equipment technology continues to evolve, end-users are placing increasingly high demands on equipment performance, automation, and sustainability — and the decanter centrifuge industry is no exception.
