GN Trenchless Mud Recycling Systems for Overseas Engineering Company

As global infrastructure development accelerates, trenchless technology and tunnel boring machine (TBM) operations have become indispensable for constructing pipelines, utility networks, and underground transit systems with minimal surface disruption. A critical factor determining the success, cost efficiency, and environmental compliance of these projects is effective drilling fluid and slurry management. GN Solids Control, a professional manufacturer of solids control equipments and customized mud tank system, has established a strong international presence by delivering customized trenchless mud recycling systems and TBM slurry separation plants to overseas engineering companies all of the world.


GN trenchless mud recycling systems are engineered to recover and reuse drilling fluids (typically bentonite mud) in horizontal directional drilling (HDD), pipe jacking, and piling operations. These systems reduce waste disposal costs, minimize environmental impact, and protect high-pressure drilling equipment from abrasive solids.

The GN C Series represents a flagship solution for medium to large-scale drilling operations. Unlike basic economy models, the C Series integrates mud recycling, storage, and mixing functions into a single, self-contained package, eliminating the need for separate storage tanks and mixing equipment. Available models include:

GNMS-200C: 200 GPM (50 m³/h)
GNMS-400C: 400 GPM (100 m³/h)
GNMS-600C: 600 GPM (150 m³/h)
GNMS-1000C: 1000 GPM (200 m³/h)

For slurry shield tunneling and pipe jacking projects, GN manufactures complete TBM slurry separation plants designed to handle the large volumes of slurry mixed with sand and stones generated during excavation. These plants are engineered to deliver high-performance solid-liquid separation, maintaining tunnel face stability, reducing cutter wear, and ensuring smooth TBM operation.

GN TBM slurry separation plants are available in multiple configurations to suit different tunnel diameters and project scales:
GNTBM-260B: 260 m³/h processing capacity
GNTBM-360B: 360 m³/h processing capacity
GNTBM-500B: 500 m³/h processing capacity

4 Sets Drilling Mud Tank Cleaning Waste Water Treatment Unit for Africa

Recently 4 sets of drilling mud tank cleaning waste water treatment unit are ready for delivery to Africa.
The delivery of these four units marks a significant step in supporting sustainable drilling practices in Africa. In many African oil and gas operations, environmental regulations are becoming increasingly stringent. The improper disposal of tank cleaning wastewater which often contains heavy solids, oil, and chemicals will poses a significant environmental risk.

The four units of tank cleaning waste water treatment unit being shipped are engineered to provide a comprehensive zero- discharge solution. By effectively separating solids, oil, and water, the system allows for the recycling of the water back into the drilling process or its safe disposal, while recovering valuable drilling fluids.
The automatic tank cleaning unit can be made into complete skid system and 3 part system according to the footprint of the jobsite. The main components including strainer, suction pump, chemical doing unit, static mixer, inclined plate clarifier ( IPC), electrical membrane pump, buffer tank, centrifugal pump, and explosion proof control system.

Key Features of the Treatment Units:

High-Efficiency Separation: Utilizing advanced mechanical separation technology, the units effectively remove suspended solids and oil from the wastewater.

Compact & Modular Design: Designed for ease of transport and rapid installation, these units are ideal for remote drilling sites where space and logistics are critical.

Chemical Dosing System: An integrated automated dosing system ensures optimal treatment efficiency with minimal operator intervention.

Robust Construction: Built to withstand the harsh operating conditions typical of African oilfields, ensuring high reliability and a long service life

GN Solids control is a professional manufacturer of solids control and drilling waste management equipment. With a focus on innovation and sustainability, the company provides solutions to oilfields worldwide, helping the operators to reduce their environmental footprint and improve drilling efficiency.

GN Solids Vauum Pump and Decanter Centrifuge for Middle East Client

The Middle East and North Africa (MENA) region presents some of the most demanding operating conditions for oil and gas drilling operations anywhere in the world.
GN Solids Control, a global manufacturer of solids control and drilling waste management equipments, has been serving the Middle East market for many years. With a deep understanding of regional challenges and a proven track record of successful deliveries, GN provides integrated solutions that combine advanced solids vacuum pumps and decanter centrifuges to help clients achieve operational excellence.

GN Solids Vacuum Pump:

For Middle Eastern projects, the GN Solids Vacuum Pump is deployed to extract oily sludge from pits and separators. The pneumatic design is intrinsically safe, preventing ignition risks in explosive environments while ensuring compliance with international safety standards. This makes it particularly valuable for:

  • Pit cleaning and sludge removal: Efficiently transferring accumulated sludge from drilling waste pits
  • Waste mud transfer: Moving high solids content drilling waste across site
  • Tank bottom cleaning: Removing residual sludge from storage tanks and separators
  • Hazardous waste recovery: Safe handling of materials in Zone 1 hazardous areas

GN Decanter Centrifuge:
GN manufactures decanter centrifuges with bowl diameters ranging from 9 inches (220 mm) to 30 inches (760 mm), accommodating a wide spectrum of processing requirements. Key features include:

The use of Decanter Centrifuges in Drilling Operations:

Fine Solids Removal: After primary separation equipment such as shale shakers, desanders, and desilters remove larger cuttings, the decanter centrifuge tackles the fine and ultra-fine solids that remain suspended in the drilling fluid.

Barite Recovery: Barite is an expensive weighting agent used to increase mud density. The decanter centrifuge can recover barite from drilling fluids, significantly reducing operating costs. By separating high gravity solids from low-gravity solids, the centrifuge enables operators to reuse valuable weighting materials.

Waste Volume Reduction: By removing solids from drilling fluids, the decanter centrifuge reduces the volume of waste requiring disposal.
