Hydrovac excavation continues to grow across North America due to its precision, safety, and reduced risk of damaging underground utilities. However, one major challenge remains for contractors and disposal facilities—handling and processing hydrovac slurry efficiently and cost-effectively.

The GNLW454GT Mud Dewatering Centrifuge from GN Solids Control offers a high-performance, compact, and fully automated solution designed specifically for the demanding characteristics of hydrovac waste. With the rising cost of disposal fees and tightening environmental regulations, this system enables operators to dramatically reduce slurry volume while recovering clean water for reuse.

High-Performance Dewatering Designed for Hydrovac Slurry

Hydrovac waste contains a mixture of water, clay, silt, sand, and organics. The GNLW454GT is engineered to separate these components with exceptional efficiency through a combination of:

• 18-inch bowl diameter
• High G-force for maximum dewatering
• Tungsten carbide wear protection
• Optimized feed zone for abrasive solids
• Variable frequency drive (VFD) for speed control

The result is drier solids discharge and cleaner clarified water, reducing transport and disposal costs by up to 70%.

Integration With Polymer Injection Systems

When paired with GN’s automatic polymer dosing unit, the GNLW454GT achieves high flocculation performance even with ultra-fine particles such as clay and silt. This is especially important for hydrovac slurry where the particle size distribution is often below 10 microns.

The system can be installed as a standalone dewatering module or integrated into a complete hydrovac slurry recycling plant.

Lower Disposal Costs and Environmental Impact

Hydrovac operators are increasingly focused on cost reduction and sustainability. By using the GNLW454GT centrifuge, companies can:

• Reduce waste volume sent to disposal facilities
• Decrease trucking and fuel costs
• Recover water for onsite reuse
• Meet municipal and environmental discharge requirements

This makes the unit an ideal investment for hydrovac contractors, waste management facilities, and municipal treatment sites.

Why Choose the GNLW454GT?

• Heavy-duty construction for abrasive solids
• Continuous, automatic operation
• Small footprint for jobsite or plant use
• Easy integration with pumps, screens, and tanks
• Proven performance in North American hydrovac applications

If you’re looking to improve the efficiency of your hydrovac slurry management, the GNLW454GT Mud Dewatering Centrifuge is a reliable, high-capacity solution designed to meet the toughest operational demands.

GN Separation is proud to continue developing cutting-edge solutions that cater to the specific needs of our global clientele. This containerized tank cleaning and oil sludge treatment system is a testament to our dedication to innovation, quality, and sustainability.

 

Managing oily sludge is a critical challenge for environmental service companies operating in the oil and gas sector. In the United States, strict regulations require effective separation technologies to reduce hazardous waste volumes while recovering valuable resources. For a recent project in the U.S., GN Separation’s GNLWS554 three-phase decanter centrifuge has been selected to address these challenges, offering continuous separation of oil, water, and solids from complex sludge streams.

The GNLWS554 model is specifically engineered for separating emulsified and viscous oil sludges with high solids content. Its three-phase design enables simultaneous separation of oil, clarified water, and dewatered solids in a single continuous process. This capability is essential for treatment plants dealing with tank bottom sludge, API separator residues, or soil washing waste streams.
At the core of its operation is a large-diameter, high-speed rotating bowl that generates powerful centrifugal forces. These forces separate phases based on density differences, with an internal screw conveyor transporting solids to the discharge ports. The machine features wear-resistant materials and a variable-pitch conveyor to handle abrasive sludge while minimizing maintenance downtime.

For the U.S. project, the GNLWS554 was selected based on its processing capacity and its ability to meet local discharge and recycling requirements. By recovering oil suitable for reuse or sale, clarifying water for reuse or discharge, and reducing the volume of solids sent for disposal, the system helps the plant lower operating costs and comply with environmental regulations.

Integration with other treatment equipment is another key aspect. In this project, the decanter centrifuge is used in conjunction with progressive cavity feed pumps that handle viscous sludges reliably. Chemical dosing systems are employed to enhance phase separation, while storage tanks manage recovered oil and water streams. This integrated approach allows for automation and streamlined operation, reducing labor costs and operational risks.
Additionally, the GNLWS554 is designed as a skid-mounted unit, making it easier to transport, install, and maintain. For modular or mobile treatment setups, this is a significant advantage. Companies working on remediation projects or tank cleaning services often require flexible equipment that can be deployed to multiple sites efficiently.
Beyond cost savings, the three-phase decanter centrifuge supports sustainability goals by enabling resource recovery and reducing waste sent to landfills. In a regulated market like the U.S., offering an environmentally responsible solution can be a competitive advantage for service providers.
Overall, this project showcases the practical value of advanced separation technology in tackling real-world challenges in oily sludge management. The GN GNLWS554 three-phase decanter centrifuge exemplifies how engineering solutions can help companies meet stringent environmental standards while delivering efficient, reliable, and cost-effective operations.
