Desander Desilter

Hydrovac excavation, a non-destructive digging method, generates large volumes of contaminated mud that demands efficient treatment to meet environmental standards. GN Solids Control, a leader in separation technology, presents the GNLW454GT mud dewatering centrifuge—engineered to tackle this challenge with unmatched performance and cost-effectiveness.

At the core of the GNLW454GT lies an 18-inch (450mm) diameter bowl with an impressive 74-inch (1880mm) length, delivering a 4:1 length-to-diameter ratio that ensures thorough separation of low-gravity solids. Powered by a 37/45/55KW main motor and 11/15/22KW back-drive, this centrifuge operates at a maximum bowl speed of 3437RPM, generating up to 3000G force—enabling it to capture solids as small as 2-5μm with exceptional efficiency.

GN Solids Control’s GNLW454GT redefines mud dewatering by balancing high throughput, separation precision, and operational flexibility—helping businesses reduce disposal costs and achieve environmental compliance. Contact us to learn how this centrifuge can optimize your separation processes.

GNLW224 Dewatering Centrifuges Ready for Overseas Client FAT

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.
