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.
