In underground construction, Trenchless technology and Vacuum Excavation are two widely used yet very different approaches. While both are designed to minimize surface disruption, they serve different project needs.

Trenchless methods, such as Horizontal Directional Drilling (HDD), are ideal for creating underground passages for pipelines or cables without the need for open trenches. They typically handle large fluid volumes and require complete mud recycling systems to ensure efficient drilling. Equipment such as desanders, desilters, and high-performance centrifuges play a central role in processing drilling fluids.

Vacuum Excavation, on the other hand, is widely applied in utility exposure, daylighting, and sensitive soil removal. Its systems manage smaller flow rates, but the screening process often requires larger surface areas to efficiently separate solids from the slurry. This makes it more focused on precision and safety rather than volume.

Recently, GN Solids Control delivered a complete Vacuum Excavation mud treatment system for a U.S. client. The package included a coarse screening module, fine screening module, desander module, and a large-bowl decanter centrifuge. With nearly two decades of experience, GN continues to expand its solutions to meet diverse client requirements across both trenchless and vacuum excavation industries.

This shipment once again demonstrates GN’s capability to provide advanced solid-liquid separation equipment that meets the growing global demand for efficient sludge treatment and wastewater management.

Meeting the Need for Efficient Sludge Dewatering

Across the world, municipalities and industrial operators are under pressure to manage sludge more effectively. Increasing environmental regulations and higher disposal costs make reliable dewatering technologies essential. Decanter centrifuges have become the preferred solution for many projects, thanks to their ability to reduce sludge volume, recover clean water, and minimize overall operating costs.

By supplying the GNLW364-VFD centrifuge to an international client, GN continues to expand its global footprint in the environmental sector and supports sustainable waste management initiatives.

Product Overview: GNLW364-VFD Decanter Centrifuge

The GNLW364-VFD centrifuge is designed as part of GN’s 14-inch bowl series, but it features a longer bowl compared with the standard GNLW363 model. The bowl measures 360 mm in diameter and nearly 1.52 meters in length, which significantly increases the separation area and improves the dryness of discharged solids. This makes it particularly well-suited for demanding sludge dewatering applications.

Key Technical Highlights

Instead of presenting figures in a table format, the performance of the GNLW364-VFD can be summarized in practical terms:

• The centrifuge can process up to 55 cubic meters of slurry per hour at peak load, while typical operations average about 35 cubic meters per hour.

• Its bowl reaches speeds close to 4,000 revolutions per minute, creating a centrifugal force of more than 3,200 G. This ensures the efficient removal of fine particles in the 2–5 micron range.

• Operators can adjust the differential speed between the bowl and the screw conveyor from 0 up to 65 RPM, offering great flexibility for different sludge types.

• Power is delivered by a main motor ranging from 22 to 37 kW, supported by a 7.5 to 11 kW back drive motor. A 7.5 kW feed pump is recommended for stable material feeding.

This intelligent combination of power, speed, and adjustability allows the GNLW364-VFD to perform efficiently under various sludge conditions, making it a versatile piece of equipment for wastewater and environmental treatment.

Built for Durability and Reliability

To ensure long service life, the centrifuge is manufactured with a duplex stainless steel bowl that is centrifugally cast for maximum strength. Wear parts such as the conveyor are protected with tungsten carbide tiles, while the feed zone and discharge areas are fitted with replaceable inserts. Tungsten carbide plows continuously clear solids from the discharge outlet, preventing material buildup.

All rotating components are supported by SKF premium bearings, well known for reliability and extended service life. Together, these features reduce downtime and minimize maintenance costs for operators.
