GN Solids Control has successfully delivered 3 sets of self-contained HDD mud recycling systems to a European client, including 2 units of GNMS-400C and 1 unit of GNMS-200C — both belonging to the brand’s Self-Contained Mud Recycling series.
The GNMS C series (represented by GNMS-400C) is an all-in-one solution, integrating mud recycling, storage, and mixing functions to suit space-constrained HDD job sites. Key specs differentiate the two models: the GNMS-400C offers 100 m³/h (440GPM) capacity, equipped with a GN cleaner (GNZS594K-S8NK) and mixing hopper. The GNMS-200C provides 45 m³/h
(200GPM) capacity, paired with its own cleaner (GNZJ754K-S4NK) and matching hopper.
Tailored for European HDD projects, these systems optimize mud treatment efficiency, reduce waste, and cut on-site costs. This shipment reinforces GN’s status as a trusted provider of specialized HDD mud solutions for global trenchless construction sectors.

A complete wastewater treatment system manufactured by GN Solids Control has been shipped to an African oilfield to support drilling and produced-water treatment. The package integrates four major functional modules: the Pre-Mixing module, the decanter centrifuge module, the chemical dosing system, and the clean-water recovery and transfer module. This modular design ensures reliable solids-liquid separation and stable operation in demanding oilfield environments.
The process begins with the Pre-Mixing module, which homogenizes incoming wastewater containing mud, fine solids, and oil residue. Proper Pre-Mixing greatly improves downstream separation efficiency and helps maintain consistent feeding conditions for the decanter centrifuge.
The second stage features the high-speed decanter centrifuge, which generates strong G-force to remove fine and ultra-fine solids. GN’s centrifuge technology ensures continuous operation, low maintenance, and high clarity of discharged liquid.
To enhance separation performance, the chemical dosing module prepares and injects flocculants automatically. Accurate dosing helps the centrifuge capture ultra-fine particles and produce cleaner water suitable for reuse.
Finally, the clean-water recovery module collects and transfers clarified water to storage or reuse points. This reduces freshwater consumption and improves the environmental footprint of the oilfield operation.
With integrated Pre-Mixing, decanter centrifuge, chemical dosing, and water-recycling technologies, GN Solids Control continues delivering reliable solutions for global wastewater treatment challenges.

GN Solids Control has successfully shipped a new package of drilling cuttings treatment equipment to a long-term Middle East customer. The shipment includes three GNZS594K High-G Drying Shakers 
and two GNCD930G Vertical Cuttings Dryers, which together form a highly efficient drilling waste management solution for demanding drilling operations.
and two GNCD930G Vertical Cuttings Dryers, which together form a highly efficient drilling waste management solution for demanding drilling operations.The three GNZS594K high-G units are designed for heavy-duty dewatering and fast solids removal. Each drying shaker features strong vibration performance, a large screen area, and a reinforced structure to handle high mud loading in both land and offshore drilling projects. By applying adjustable G-forces, the drying shaker effectively reduces moisture content in discharged cuttings, lowering waste volume and improving overall mud recycling efficiency.
The two GNCD930G vertical dryer units play an equally important role in
handling oil-based and synthetic-based drilling cuttings. Each dryer provides high liquid recovery, stable operation, and long service life, making it a preferred choice for drilling contractors. The dryer significantly minimizes the discharge of oil-contaminated cuttings and helps operators meet strict environmental regulations in the Middle East region.
