Its consistent performance ensures that plants can operate sustainably while meeting local wastewater treatment requirements.
In summary, the GN Dewatering Screw Press offers an efficient, reliable, and cost-effective solution for treating food plant wastewater overseas. Its robust construction, high dewatering efficiency, and ease of maintenance make it an ideal choice for operators seeking to optimize wastewater management while minimizing environmental impact.

As drilling operations become more complex and safety requirements continue to tighten, effective gas control in drilling fluids has become a critical factor for successful project execution. In response to these challenges, GN Solids Control has supplied **nine sets of drilling mud vacuum degassers** to a European client, delivering a reliable solution to enhance both operational stability and safety performance.

Rather than being viewed as a standalone piece of equipment, the vacuum degasser plays a vital role within the entire solids control system. Gas intrusion into drilling fluid can occur at various stages of drilling, especially when encountering gas-bearing formations. If not properly removed, gas-cut mud can lead to reduced fluid density, unstable circulation, and increased risk of well control incidents. By integrating efficient degassing technology, operators can maintain consistent drilling parameters and avoid costly disruptions.

GN’s vacuum degassers are designed to function as a **stabilizing unit within the drilling fluid circulation system**. Installed downstream of primary solids control equipment, the degasser continuously processes returning drilling fluid, removing both free and entrained gases before the fluid proceeds to subsequent treatment stages. This ensures that downstream equipment such as desanders, desilters, and centrifuges can operate under optimal conditions without gas interference.

The system operates by creating a controlled vacuum environment, allowing gas to separate rapidly from the liquid phase. This process not only restores the density of the drilling fluid but also improves its overall rheological properties. As a result, drilling performance becomes more predictable, and the risk of pressure fluctuations within the wellbore is significantly reduced.

From a project management perspective, supplying **nine identical units** provides the client with a standardized equipment fleet. This standardization simplifies installation, operation, and maintenance across multiple rigs or drilling sites. Operators benefit from consistent performance, while spare parts management and technical training become more efficient and cost-effective.

Another important aspect of this project is GN’s focus on **long-term reliability and ease of maintenance**. The vacuum degassers are built with durable components and optimized internal structures to handle continuous operation in demanding drilling environments. The simplified mechanical design allows for quick inspection and servicing, helping reduce downtime and maintain steady production schedules.

In addition, GN’s equipment can be configured to meet European safety and compliance requirements, ensuring that the degassers are suitable for use in both standard and hazardous environments. This flexibility allows the client to deploy the equipment confidently across a range of drilling applications.

Through this delivery, GN Solids Control once again demonstrates its commitment to providing system-oriented solutions rather than individual equipment. By ensuring effective gas removal and supporting stable drilling fluid performance, GN vacuum degassers contribute directly to safer, more efficient, and more reliable drilling operations.

With proven technology and global project experience, GN continues to support drilling contractors worldwide with practical solutions that address real operational challenges.

As large-scale urban infrastructure projects continue to expand in South Korea, shield tunneling technology plays an increasingly important role in constructing underground transportation networks, utility pipelines, and municipal infrastructure. To support these demanding projects, GN Solids Control has supplied six packages of TBM slurry separation plants designed for slurry balance tunnel boring machines.

In slurry balance TBM operations, the excavation process generates large volumes of slurry containing soil, sand, gravel, and fine particles. If not properly treated, these solids can affect slurry performance, increase equipment wear, and disrupt the tunneling process. A reliable slurry separation system is therefore essential to maintain efficient TBM operation and ensure stable excavation conditions.

GN’s slurry separation plants are engineered to handle high-capacity slurry treatment requirements, with processing capacities of 500 m³/h and 750 m³/h. These systems are designed to continuously separate excavated solids from drilling slurry and recycle the cleaned fluid back into the tunneling circulation system. This recycling process reduces the consumption of fresh water and bentonite while lowering overall waste disposal costs.

Each of the six systems is equipped with three essential treatment modules: a scalping screen, a desander, and a desilter. These components work together to achieve multi-stage separation. The scalping screen removes oversized particles and debris at the initial stage, protecting downstream equipment and ensuring smoother processing. The desander module then uses hydrocyclone technology to separate medium-sized sand particles from the slurry. Finally, the desilter stage further removes fine particles, improving the overall slurry quality and enabling effective reuse.

One of the notable features of GN’s slurry separation technology is its modular system architecture. Each module is built as a self-contained unit, allowing easy transportation, quick installation, and convenient maintenance. This modular design also provides flexibility for project engineers to arrange the system layout according to site conditions, which is especially valuable for tunneling sites where available working space may be limited.

The compact footprint of the system is another key advantage. Despite its high processing capacity, the equipment is designed to occupy minimal space, allowing efficient use of construction areas. Fast assembly and disassembly further reduce project preparation time and help contractors maintain tight construction schedules.

In addition to operational efficiency, durability is a core consideration in GN’s equipment design. Shield tunneling slurry often contains highly abrasive particles that can cause significant wear to separation equipment. GN uses high-quality materials and robust structural designs to ensure long-term reliability and stable performance under continuous operation.

The successful delivery of six TBM slurry separation plants to South Korea demonstrates GN Solids Control’s growing presence in the global tunneling and trenchless construction market. With advanced separation technology, flexible modular systems, and proven reliability, GN continues to support infrastructure projects worldwide.

Diamond core drilling projects often operate in remote areas where access to stable electrical power is limited and operating conditions can change rapidly. For these challenging environments, GN Solids Control has delivered three packages of hydraulic drive mini centrifuge units designed to provide reliable solids separation with maximum operational flexibility.

Unlike conventional electrically driven centrifuges, these units are powered through a diesel-driven hydraulic power system. The diesel power pack supplies hydraulic oil to a hydraulic motor, which then directly drives the decanter centrifuge. This drive configuration significantly reduces dependency on electrical infrastructure and makes the system especially suitable for off-grid drilling locations.

One of the main advantages of hydraulic drive technology is its ability to deliver high torque at low and variable speeds. In diamond core drilling, drilling fluid properties and solids loading can fluctuate as drilling progresses through different formations. The hydraulic motor responds smoothly to these changes, maintaining stable centrifuge operation and protecting mechanical components from overload or shock.

The mini centrifuge units are designed with portability and ease of deployment in mind. Their compact structure allows them to be transported alongside drilling rigs and quickly installed at site with minimal civil preparation. This is particularly important for exploration drilling projects that require frequent relocation as new boreholes are drilled.

Operational control is another area where hydraulic drive systems offer clear advantages. Centrifuge speed and differential torque can be adjusted by regulating hydraulic flow and pressure, allowing operators to fine-tune separation performance without complex electrical controls. This straightforward control method simplifies training requirements and reduces the risk of operational errors in the field.

From an efficiency standpoint, the hydraulic drive mini centrifuge plays a vital role in improving overall drilling fluid management. By removing fine solids from the drilling fluid, the system helps maintain consistent fluid properties, reduce wear on drilling tools, and extend the service life of downstream equipment. Recovered drilling fluid can be reused, reducing both water consumption and waste disposal volumes.

Durability is a key design consideration for GN’s hydraulic drive centrifuge units. All major wear components are manufactured from abrasion-resistant materials, ensuring long service life even when handling fine, abrasive solids commonly generated during diamond core drilling. The robust mechanical and hydraulic structure also minimizes routine maintenance and supports continuous operation in harsh field conditions.

Supplying three independent centrifuge packages gives the drilling contractor greater operational flexibility. The units can be deployed individually or in parallel depending on project scale, drilling depth, or fluid volume, providing a scalable solution that adapts to different project requirements.

Through this project, GN Solids Control once again demonstrates its expertise in developing application-specific solids control solutions. By combining diesel-powered hydraulic systems with compact decanter centrifuges, GN delivers reliable, flexible, and field-proven equipment that supports efficient diamond core drilling operations worldwide.
