GN Solids Control has successfully supplied three packages of HDD Mud Recycling Units to a European trenchless construction contractor, supporting multiple horizontal directional drilling projects across the region. The project includes two sets of GNMS-400C mud recycling systems and one set of GNMS-200C system, designed to meet different drilling capacities while maintaining consistent performance and fluid quality.

Horizontal Directional Drilling projects demand reliable and efficient mud recycling solutions to ensure stable borehole conditions, reduce drilling fluid consumption, and minimize environmental impact. GN’s compact yet powerful mud recycling units are specifically engineered for HDD, pipe jacking, and microtunneling applications, making them an ideal choice for European infrastructure projects where space, efficiency, and compliance are critical.

The GNMS-400C Mud Recycling Unit is designed for medium-capacity HDD operations. Each system integrates a high-performance shale shaker with a desander and desilter module, allowing effective removal of sand and fine solids from drilling fluids. This configuration helps maintain proper mud viscosity and density, improving drilling efficiency and protecting downstream pumps and tools from excessive wear.

The GNMS-200C Mud Recycling Unit serves smaller drilling operations or pilot holes, offering a compact footprint without compromising separation efficiency. Despite its smaller size, the system delivers reliable solids removal, making it suitable for urban construction sites where limited space and mobility are key concerns.

All three units feature modular skid-mounted designs, allowing for easy transportation, fast installation, and flexible operation across different job sites. The systems are equipped with durable centrifugal pumps, wear-resistant cyclones, and high-quality vibration components to ensure stable performance under continuous operation. GN’s engineering approach emphasizes simplicity and robustness, reducing maintenance requirements and downtime during critical drilling stages.

Environmental protection is another major advantage of GN mud recycling systems. By efficiently cleaning and reusing drilling fluids, the systems significantly reduce fresh water consumption and waste slurry disposal volumes. This aligns well with Europe’s strict environmental regulations and sustainability goals for trenchless construction projects.

In addition, GN provides technical support, system customization, and commissioning guidance to ensure seamless integration with the client’s HDD equipment. From system layout optimization to operational training, GN works closely with customers to maximize project efficiency and return on investment.

This delivery of 3 package HDD mud recycling units highlights GN Solids Control’s strong capability in providing reliable, field-proven solutions for trenchless construction worldwide. With a wide range of system capacities and configurations, GN continues to support infrastructure development projects by offering efficient, cost-effective, and environmentally responsible mud management solutions.

For HDD contractors seeking dependable mud recycling technology, GN remains a trusted partner for both standard and customized solids control systems.
