GN Solids Control recently delivered a Hydrovac Slurry Separation System to a client in the United States, marking another step in the company’s mission to provide environmentally responsible and cost-effective solutions for the excavation industry. This delivery highlights GN’s capability to support contractors dealing with the unique challenges of hydrovac operations.

Hydrovac excavation, widely used in North America for exposing underground utilities, trenching, and pipeline installation, generates substantial volumes of slurry. This slurry, composed of soil, clay, sand, and water, must be processed before disposal or reuse. Traditional methods—such as direct hauling of liquid waste—are costly, time-consuming, and environmentally unsustainable. GN’s system changes the equation by enabling on-site slurry separation and recycling.

Breaking Down the System
The delivered unit includes four key processing modules:
Coarse Screening Module: Removes large particles and debris, protecting downstream equipment and improving system reliability.
Fine Screening Module: Employs high-performance shale shakers to separate medium solids such as sand and silt, ensuring smoother processing.
Desander Module: Hydrocyclones remove particles down to around 40 microns, producing cleaner slurry and extending centrifuge lifespan.
Large Bowl Decanter Centrifuge Module: This high-speed centrifuge handles the fine separation stage, delivering clarified water for reuse and compact solids for easier disposal.
Together, these modules form a complete processing chain that allows contractors to manage slurry at the jobsite instead of relying solely on disposal facilities.

Advantages for Contractors
The benefits of GN’s Hydrovac Slurry Separation System go far beyond equipment performance:
Operational Savings: By separating water and solids on-site, contractors can significantly cut down hauling and disposal costs.
Regulatory Compliance: Local authorities increasingly enforce strict waste handling and discharge standards. GN’s system helps clients meet these requirements with confidence.
Water Recycling: Clean water recovered during the process can be reused in excavation, reducing the consumption of fresh water.
Mobility & Modularity: Each module is designed for flexible transport and quick installation, making the system suitable for both short-term and long-term projects.
Reduced Downtime: Reliable GN equipment ensures continuous operation, even in demanding conditions.

A Commitment to Sustainable Solutions
The successful delivery to the U.S. market reinforces GN’s growing presence in North America. More importantly, it demonstrates GN’s ongoing commitment to supporting sustainable construction practices. By helping contractors minimize environmental impact and optimize resource use, GN contributes to a more efficient and eco-conscious excavation industry.
As urban infrastructure expands and environmental regulations tighten, the demand for effective slurry management solutions will only grow. GN Solids Control is well positioned to meet this demand with proven technology, global service support, and extensive application experience.
