GN Solids Control is pleased to announce the successful delivery of a GNLW364-VFD sludge dewatering centrifuge to an overseas environmental protection company. 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.
Typical Applications
The GNLW364-VFD centrifuge is widely applicable across several industries, including:
-
Municipal wastewater treatment plants, where it reduces sludge volume and disposal costs.
-
Industrial wastewater treatment, separating solids, water, and oil in complex effluents.
-
Drilling mud recycling, enabling the recovery of valuable drilling fluids and reducing waste.
-
Environmental remediation projects, handling contaminated soil, sediments, and slurry streams.
