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.
