GN Solids Control has completed a full Dewatering Unit package—featuring the GNLW224 horizontal decanter centrifuge, polymer dosing unit, and sludge dewatering centrifuge—now ready for Factory Acceptance Test (FAT) for an overseas client.

Traditional solids-control equipment removes particles above 5 microns, while ultra-fine solids continue accumulating in the drilling mud. To stabilize fluid properties, operators often dilute mud with large volumes of water, increasing both cost and waste.

To solve this, GN provides a chemically enhanced Dewatering Unit that uses polymer flocculation and high-speed separation to remove solids below 5 microns. This produces cleaner water suitable for reuse or controlled discharge—reducing water consumption and waste generation.

How the dewatering process works:

• The automatic dosing system prepares polymer solution.

• A slurry pump transfers mud into the decanter centrifuge.

• Polymer is injected into the feed line via the dosing pump.

• Chemical and mud are fully mixed in the feed tube.

• The high-speed centrifuge separates ultra-fine solids and improves fluid quality.

GN also offers 20-ft and 40-ft containerized Dewatering Unit packages for drilling mud treatment, municipal sludge, tunneling, and environmental applications.

The upcoming FAT will verify mechanical performance, dosing accuracy, automation logic, and full system integration before shipment. As a global supplier, GN continues to deliver efficient and reliable separation solutions for drilling and industrial projects worldwide.

From November 3rd to 6th, 2025, GN Solids Control successfully showcased its advanced separation technology at ADIPEC 2025, one of the world’s largest and most influential oil and gas exhibitions. Located at Booth No. 10453, Hall 10, GN’s booth attracted both long-term partners and new visitors from across the global energy industry.

This year, GN highlighted two of its core products — the Decanter Centrifuge and the Shale Shaker. These equipment samples demonstrated GN’s commitment to efficient, reliable, and environmentally responsible solids-liquid separation solutions. Visitors were particularly impressed by the high-quality build and innovative design that enhance oilfield performance while minimizing environmental impact.

As oil and gas operations continue to focus on sustainability, GN Solids Control remains at the forefront of providing technologies that reduce waste, recover valuable resources, and protect the environment. Through continuous innovation and global cooperation, GN aims to make oil development cleaner, smarter, and more efficient.

The success at ADIPEC 2025 further strengthened GN’s position as a trusted global partner in solids control and waste management systems. GN sincerely thanks all visitors for their support and looks forward to deepening cooperation in future projects.

Recently, multiple sets of GN K Series Linear Motion Shale Shakers have been successfully delivered to a valued client in the Middle East for use in their drilling fluids solids control system.

As the first-stage solids control equipment, the Shale Shaker plays a crucial role in the overall performance of the drilling mud system. The GN K Series shale shaker is designed and manufactured by GN Solids Control, integrating advanced technology from both domestic and international sources, as well as GN’s own engineering innovations.

The GN K Series shale shaker offers several key advantages:

• High G-force and wide screen area ensure efficient solids separation.

• The entire shaker deck is heat-treated to relieve welding stress, providing strong vibration endurance.

• Equipped with Italian OLI brand vibration motors for reliable performance.

• Quick screen tightening system allows fast installation and replacement.

• Nylon wedge blocks and polyurethane sealing components enhance wear and corrosion resistance, ideal for high-temperature drilling environments in the Middle East.

• The adjustable deck angle design provides flexibility to handle different mud conditions and flow rates.

GN provides several models within the K Series, including GNZS594K, GNZS595K, and GNZS596K, covering a wide range of drilling applications from oil & gas to trenchless HDD. Proven in numerous international drilling projects, GN shale shakers are recognized for their durability, reliability, and cost efficiency.
