We are pleased to highlight the deployment of a specialized GN Decanter Centrifuge System for oilfield wastewater treatment at a project in Africa.

Mixing Module: Ensures optimal conditioning of the wastewater feed for effective separation.

Decanter Centrifuge Module: The core separation unit, utilizing high G-force to efficiently separate solids from liquids.

Chemical Dosing Module: Provides precise addition of flocculants or other treatment chemicals to enhance separation performance.

Clean Water Recovery & Transfer Module: Handles the conveyance of clarified water for safe disposal or potential reuse, closing the treatment loop.

At the heart of the system is GN’s advanced centrifuge technology. While the decanter centrifuge has operated on a consistent principle since the 19th century, GN elevates this proven technology through modern innovation. We design our centrifuges—including both two-phase decanters and three-phase models—around specific separation tasks and client requirements. The use of resilient, high-quality construction materials significantly enhances durability and performance in demanding applications.

A key GN advantage lies in our in-house control expertise. We operate a dedicated branch for designing PLC and electrical control systems. This vertical integration allows us to implement superior electrical components and sophisticated control technology. As a result, the performance, reliability, and operational availability of our decanter and three-phase centrifuges are substantially improved, ensuring consistent results with minimal downtime.

This system delivered to Africa is more than just equipment; it represents a holistic approach to wastewater management. By integrating mixing, chemical dosing, high-efficiency separation, and water handling into a cohesive unit, we help operators reduce environmental impact, recover valuable resources, and achieve cost-effective compliance.

GN remains dedicated to pushing the boundaries of separation technology, delivering customized solutions that combine proven principles with cutting-edge control and robust design for the global energy sector.

We are excited to announce the successful supply of a complete set of GN drilling cuttings treatment equipment to a valued customer in the Middle East. This shipment underscores our commitment to providing advanced, efficient, and reliable solids control solutions to the global oil and gas industry, particularly in key regions like the Middle East.

The order includes a powerful combination of primary drying and secondary processing equipment designed to handle drilling cuttings effectively:

Three Units of GNZS594K High G Force Drying Shaker

The GN High G Force Drying Shaker is engineered for superior primary solids control and cuttings drying. It effectively processes cuttings from primary solids control equipment, recovering valuable silts and ultra-fine sands. A key advantage of this system is its ability to discharge solids in a consistently stackable and conveyable form, significantly reducing waste volume and handling costs. Furthermore, this efficient drying process achieves excellent results without the need for expensive chemicals or polymers. With its adjustable G-force of up to 8.0 G, the shaker delivers optimal performance across a wide range of drilling conditions and fluid types.

Two Units of GNCD930G Vertical Cuttings Dryer

For final-stage processing and maximum liquid recovery, the package includes two GN Vertical Cuttings Dryers. This robust equipment utilizes high centrifugal force to thoroughly dry drilled solids in oil-based or synthetic-based fluids. Its operational principle is both efficient and durable: a stainless-steel screen bowl rotates at up to 900 RPM, generating a force of 420 G to separate liquids from solids. The liquid is forced through the screen, while the dried solids are conveyed upward by a scroll (angled flights) that rotates slightly slower than the bowl. Critical wear parts, like the scroll flights, are protected with tungsten carbide to withstand abrasive solids, ensuring a long operational life and maintaining the precise gap between the scroll and bowl essential for reliable operation.

This equipment suite represents a comprehensive solution for responsible waste management. By deploying the GN High G Drying Shakers and Vertical Cuttings Dryers, our Middle East client can achieve drier solids, maximize base fluid recovery, reduce overall waste disposal costs, and meet stringent environmental standards.

GN remains dedicated to innovating and delivering cutting-edge solids control and waste management technology, helping our clients operate more efficiently, economically, and sustainably.

In demanding drilling and fluid management applications, reliability and efficiency are non-negotiable. GN Solid Control offers robust pumping solutions designed to meet these critical demands. We are proud to supply our trusted GNSB Series Centrifugal Pump and innovative JQB Series Shear Pump to clients across Europe, supporting a wide range of industrial operations.

Versatile Performance: GNSB Series Centrifugal Pump

The GNSB Series Centrifugal Pump is a workhorse engineered for transferring slurry, mud, and water with exceptional durability. Its versatility makes it an indispensable component on any rig or job site, capable of serving in multiple roles:

As a feeding pump for desanders and desilters.

As a mixing pump for Jet Mud Mixers.

As a trip pump or a supercharging pump for rig mud pumps.

Built for longevity and easy maintenance, the GNSB pump features a tungsten carbide mechanical seal and high-quality brand-name bearings. A key design advantage is the open impeller, which reduces axial thrust loads and simplifies installation, repair, and maintenance. Furthermore, its spare parts are interchangeable with many leading international pump brands, simplifying your supply chain and minimizing downtime.

Efficient Mud Preparation: JQB Series Shear Pump

The JQB Series Shear Pump represents the next step in efficient and effective mud mixing technology. This advanced system is designed to rapidly prepare high-performance drilling fluid, delivering significant operational benefits:

Rapid Mixing & Complete Hydration: Effectively mixes and hydrates materials added to the drilling fluid, ensuring optimal performance.

Cost and Time Savings: Significantly reduces mud configuration time and saves valuable mud materials by minimizing waste.

Superior Fluid Performance: Provides the high-quality, consistent mud essential for successful well drilling operations.

A Complete Fluid Management Solution

Together, the GNSB Centrifugal Pump and JQB Shear Pump form a powerful combination for any project requiring reliable fluid transfer and superior mud mixing. By ensuring equipment durability, operational flexibility, and efficient material usage, GN helps operators reduce total cost of ownership and enhance on-site productivity.

GN Solid Control is committed to providing advanced, practical solutions for the global industry.
