GN Dewatering Centrifuge for Contaminated Soil Washing Slurry Commisioned Successfully in Middle East

GN Separation recently completed the successful commissioning of a containerized sludge dewatering system at a client site in the Middle East. The project has received high praise from the client, highlighting both the outstanding performance of the GNLW654-VFD decanter centrifuge and the technical expertise of GN’s after-sales service engineers.

 At the heart of the system is the GNLW654-VFD sludge dewatering decanter centrifuge, a high-capacity unit specifically engineered for challenging solid-liquid separation tasks. In this case, the centrifuge was deployed to treat effluent water generated during the washing of oil-contaminated soil—a critical process in the region’s unique environmental context.

The Middle East, known for its vast oil reserves, faces ongoing environmental challenges, particularly due to oil spills during extraction and transportation. In the region’s arid desert landscape, soil is a limited and valuable resource. Reclaiming contaminated soil through effective washing and treatment is not only essential for environmental protection but also for sustainable land management.

At the client’s site, the remediation process begins with intensive washing of oil-contaminated soil using water combined with specialized chemical agents. This liberates oil and fine particles from the soil. The resulting slurry is then routed to a flotation tank, where air bubbles aid in the separation of oil and suspended solids. While the surface scum of oil and particles is removed, the remaining sludge—comprising water, residual oil, and fine solids—presents a significant treatment challenge.

This is where GN Separation’s advanced centrifuge technology proves invaluable. The GNLW654-VFD decanter centrifuge utilizes high-speed centrifugal force to efficiently separate solids from liquids, producing clarified water and a drier, more manageable sludge cake. This not only ensures compliance with environmental regulations but also reduces waste volume and disposal costs.

During commissioning, GN’s after-sales engineer meticulously adjusted key operating parameters—including bowl speed and differential speed—to optimize separation performance. The goal was to meet strict clarity requirements for the liquid discharge and achieve the desired dryness in the solid output for easier handling.

The client expressed strong satisfaction with both the equipment’s performance and the engineer’s technical capabilities. The successful deployment of the sludge dewatering system has helped the client enhance environmental compliance, reduce operational costs, and streamline their overall waste treatment process.

This project exemplifies GN Separation’s commitment to delivering customized solutions tailored to the needs of clients across industries and regions. By combining state-of-the-art equipment with expert technical support, GN continues to position itself not just as a supplier, but as a trusted partner in achieving efficient, sustainable operations.

GN Separation Shined at IE EXPO CHINA 2025

At the recently concluded IE EXPO CHINA 2025, GN Separation drew significant attention, forging new business partnerships and deepening technological exchanges with both longstanding collaborators and first-time visitors. The exhibition served as a valuable platform for the company to highlight its latest innovations in environmental water treatment and solid waste management GN Separation presented three flagship products at the event—each designed to tackle pressing challenges in environmental engineering: Solids Vacuum Pump, Fully Hydraulic Decanter centrifuge, 3 Phase Decanter Centrifuge. These systems showcased GN’s commitment to developing reliable and efficient solutions for diverse applications, from municipal sludge treatment to complex oil-water-solid separation.

Solids Vacuum Pump: Versatile Material Handling

The fully pneumatic Solids Vacuum Pump stood out as a highly adaptable solution for transporting challenging materials in both industrial and municipal sectors. Key applications include:

Sewage Sludge Removal: Cleaning sedimentation tanks in wastewater treatment plants.

Construction Slurry Transport: Handling heavy mud from construction sites.

Solid Waste Conveyance: Moving granular solids like sand, powders, and residues.

With no electrical components, the pump is ideal for explosive or hazardous environments, offering both operational safety and reduced maintenance costs. Its ability to handle materials of varying densities and particle sizes makes it a versatile asset for dynamic waste management systems.

Fully Hydraulic Decanter Centrifuge: Adaptive Dewatering Technology

GN Separation’s Fully Hydraulic Decanter centrifuge offers a dynamic alternative to traditional electric models. Designed to adjust torque in real time based on feed characteristics, it delivers optimized dewatering performance across variable sludge compositions. Key benefits include:

Adaptive Torque Control: Maintains consistent cake dryness despite fluctuating input.

Maintenance-Free Hydraulic Gearbox: Reduces downtime and long-term servicing costs.

Explosion-Proof Design: Certified for hazardous areas such as oilfields and chemical plants.

This technology is increasingly favored by municipalities and industrial facilities seeking durable, high-efficiency dewatering systems.

3 Phase Decanter Centrifuge: Precision Separation for Complex Waste Streams

The 3 Phase Decanter Centrifuge addresses the growing need for precise, simultaneous separation of light liquid, heavy liquid, and solid phases. It is ideally suited for:

Kitchen Waste Oil Recovery: Extracting edible oils from food processing waste.

Oil-Water Separation: Enhancing industrial wastewater treatment.

Oily Sludge Treatment: Recovering valuable oils in refineries and petrochemical plants.

By reducing waste volume and reclaiming resources, this centrifuge supports circular economy principles and helps users meet stringent environmental regulations.

Strategic Engagements: Advancing Innovation through Collaboration

In addition to showcasing its technologies, GN Separation engaged in strategic discussions with industry leaders and technical experts. These conversations explored collaboration opportunities in emerging markets and joint research initiatives. The company also highlighted ongoing partnerships with universities and R&D institutions, reinforcing its dedication to advancing sustainable separation technologies.
