GN Solids Control is pleased to announce the successful delivery of a GNTBM-500B Slurry Separation Plant to a major tunneling project in the Middle East. This advanced system is specifically engineered for slurry balance tunnel boring machines (TBMs) and pipe jacking operations, where efficient and reliable slurry management is critical to project success.

The GNTBM-500B is designed to deliver a robust processing capacity of 500 cubic meters per hour (2200 GPM) , ensuring continuous and effective treatment of excavated slurry. This high-throughput capability makes it an ideal solution for medium to large-scale tunneling projects requiring consistent separation performance.

Comprehensive Multi-Stage Separation Process

The GNTBM-500B incorporates a complete multi-stage separation system to ensure thorough slurry purification. The integrated treatment train includes:

Vibrating Screens (Shale Shakers) – The primary stage removes coarse particles and large debris from the incoming slurry. The system is equipped with high-efficiency vibrating screens featuring enhanced vibration force to maximize solid-liquid separation.

Desander Unit – The second stage eliminates medium-sized sand particles, protecting downstream equipment from abrasive wear.

Desilter Unit – The third stage achieves fine solids removal, delivering clean slurry ready for recirculation back to the TBM.

Decanter Centrifuge (Optional) – For projects requiring advanced dewatering or removal of ultra-fine particles, GN provides decanter centrifuges in combination with chemical dosing units. When aged or waste slurry needs to be discharged or requires removal of extremely fine particles, GN’s large-bowl decanter centrifuge can be deployed with flocculants from the chemical dosing system to dewater the slurry, discharging clean water that can be reused or returned to the system.

Modular Design for Rapid Deployment

Understanding the demands of busy construction sites, the GNTBM-500B features a compact and modular design. This allows for a smaller footprint, faster assembly and disassembly, and easier transportation between job sites. The system is truly ready for rapid deployment, minimizing downtime and maximizing productivity.

Supporting Middle East Infrastructure Development

The Middle East region continues to see significant investment in tunneling and underground infrastructure. GN Solids Control has established GN Solids MENA in the UAE to provide enhanced local sales, technical support, and spare parts availability for projects across the region. This local presence enables faster response times, improved logistics, and closer technical collaboration with clients. GN’s slurry separation plants are engineered to handle demanding conditions, including high temperatures and abrasive solids common in desert environments.

This delivery to the Middle East further demonstrates GN Solids Control’s capability to deliver specialized slurry separation solutions that meet the rigorous demands of underground engineering projects worldwide. We remain committed to providing innovative, reliable, and efficient equipment to support the global infrastructure industry.

GN Solids Control is pleased to announce the establishment of GN New Chem, a specialized company focused on chemical products and process solutions for oil and gas drilling, oilfield production, waste treatment, mining, and environmental applications.

Middle East. This delivery demonstrates our continued commitment to providing essential solids control equipment for the region’s demanding drilling operations.

ZCQ Series Vacuum Degasser

The ZCQ series vacuum degasser is a specialized device designed for the effective treatment of gas-contaminated drilling fluids. It can quickly remove various invasive gases from drilling fluids, making it a critical component for maintaining drilling fluid integrity.

Key features and benefits include:

Rapid gas removal: Effectively eliminates entrained gases such as methane, carbon dioxide, and hydrogen sulfide from drilling fluids.

Restores mud properties: Returns mud gravity to optimal levels and stabilizes viscosity, ensuring proper hydrostatic pressure and well control.

Cost reduction: Minimizes the need for costly chemical treatments and reduces non-productive time associated with fluid degradation.

Dual functionality: Can also serve as a heavy-duty agitator, making it a versatile component applicable to all types of mud circulation purification systems.

Scientifically designed structure: Achieves effective gas-liquid separation, filters out impurities, and ensures the exhaust pipe remains clear and unobstructed.

Shale Shakers

The shale shaker is the first phase solids control equipment in any drilling fluid processing system. As the key equipment in the drilling mud system, shale shaker performance directly affects the efficiency of the entire solids control system.

GN Solids Control offers comprehensive shale shaker solutions:

Customized configurations: GN can design double shakers and triplicate shakers on a single skid according to clients’ special requirements, and also supply relevant connecting manifolds.

Advanced technology: GN provides both third-generation linear motion shale shakers and fourth-generation balanced elliptical shale shakers to meet diverse operational needs.

Superior design: GNZS linear motion shale shakers incorporate advanced technology from domestic and international sources, combined with GN’s own design innovations. The complete series of shale shakers can meet customers’ variable demands.

Client feedback has consistently confirmed the advantages of GN shale shakers, including high G-force, wide screen area, compressed structure, and cost-effectiveness.

GN Solids Control is pleased to announce the successful shipment of a fully hydraulic drive decanter centrifuge and a vertical cuttings dryer to a valued client in Asia. This delivery demonstrates our continued commitment to providing advanced solids control and drilling waste management solutions across the region.

Fully Hydraulic Drive Decanter Centrifuge

The centerpiece of this shipment is the fully hydraulic drive decanter centrifuge. Unlike conventional electric motor-driven models, this centrifuge features a cutting-edge hydraulic drive system designed for demanding drilling operations.

The system drives both the conveyor and bowl from a hydraulic pump unit through two independent hydraulic oil circuits, enabling precise and flexible adjustment of bowl speed and scroll differential speed even during operation. This capability optimizes separation performance under varying feed conditions and makes the centrifuge particularly well-suited for high-temperature environments and heavy mud applications.

With fewer electrical components, the hydraulic system reduces the risk of electrical failures, simplifies troubleshooting, and minimizes downtime. The centrifuge, hydraulic drive system, and control panel are integrated on a single skid for easy rig-up and transport.

Vertical Cuttings Dryer

Complementing the centrifuge is a vertical cuttings dryer, a core piece of equipment for drilling waste management. Primarily designed to treat drill cuttings discharged from shale shakers when drilling with oil-based or synthetic-based mud, the dryer utilizes high-speed centrifugal force to effectively remove residual liquid from cuttings.
