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.
