Smart Polymer Dosing System — Enhancing Dewatering Efficiency

In any sludge dewatering process, the polymer dosing system plays a decisive role. Proper flocculant preparation and accurate dosing directly influence the formation of strong, stable flocs, which ultimately determine the separation performance of a decanter centrifuge. For this project, GN has supplied a fully automated, three-tank polymer preparation unit, equipped with precise dosage control and real-time adjustment features.

The intelligent dosing system works seamlessly with the GNLW224 centrifuge. By monitoring feed flow, sludge characteristics, and centrifuge load, the control logic automatically adjusts polymer concentration and dosing rate. This ensures optimal floc formation under varying operational conditions, helping the centrifuge achieve higher dryness, cleaner centrate, and lower polymer consumption. For end users, this means lower operational costs and more stable long-term results.

GNLW224 — Compact but Powerful Dewatering Centrifuge

The GNLW224 model is GN’s compact-size dewatering centrifuge widely used for municipal sludge, industrial wastewater, and small-scale treatment systems.

When paired with the intelligent dosing unit, the GNLW224 becomes a complete, plug-and-play dewatering package suitable for overseas installations where local commissioning resources may be limited.

Smooth Integration and Easy Operation

The entire system—including the centrifuge, dosing unit, pumps, and control cabinet—is pre-installed, wired, and tested on the skid before FAT. GN engineers simulate on-site working conditions to verify mechanical operation, control logic, safety interlocks, and communication between the dosing system and centrifuge. This integrated design allows the end user to achieve quick installation, fast startup, and minimal operational tuning.

Ready for FAT and Global Delivery

With all mechanical and electrical checks completed, the equipment is now ready for the final FAT procedure with our overseas client. After FAT approval, the system will be packed and shipped, continuing GN’s mission of delivering reliable separation technology to partners worldwide.

GN disc stack separator is an advanced piece of equipment used for high-speed, efficient separation of three-phase materials—liquid, liquid, and solid. Unlike traditional separators, the three-phase disc separator can simultaneously separate two liquids of different densities while also discharging solid materials. This makes it an essential tool in industries requiring precise separation, such as food processing, chemical engineering, and wastewater treatment.

Superior Separation Efficiency

One of the key advantages of the disc stack separator over other separation technologies, like decanter centrifuges, is its significantly higher G-force. With a G-force of up to 12,000G, compared to the 3,000G of a decanter centrifuge, the disc stack separator ensures a more thorough separation of liquids with different specific gravities, resulting in clearer liquid phases.

How It Works: The Disc Stack Design

The separator features a series of rotating discs, creating separation intervals where the material is processed under strong centrifugal force. The heavier liquid phase moves outward along the disc wall, while the lighter liquid phase moves towards the center. These phases are discharged through separate pumps, and the heavy slag accumulates and is periodically ejected.

Durable and Efficient Construction

Constructed entirely from high-grade stainless steel, the separator minimizes chemical interaction between the material and the machine surfaces. It operates with low noise and minimal energy consumption, thanks to a combination of hydrodynamic coupling and belt or helical gear drives.

Automation for Continuous Production

The PLC-controlled automatic discharge system ensures consistent performance, making it a highly automated, adaptable, and reliable solution for continuous industrial production. The separator also features overload protection, stable speed increases, and easy operation, enhancing its reliability in various industrial settings.

Conclusion: A Valuable Industrial Tool

In summary, GN disc stack separator stands out for its high efficiency, automation, and ability to handle complex separation tasks. Its versatility and reliability make it a valuable addition to any industry requiring precise liquid-solid-liquid separation.

Introduction

The mining industry is a sector that is heavily reliant on advanced technology to enhance efficiency and productivity. One such technology that has proven to be invaluable is the centrifuge. GN Centrifuges play a pivotal role in various processes within the mining industry, from mineral processing to environmental management.

Dewatering before further refinery

In mineral processing, GN centrifuges are primarily used for solid-liquid separation. They are highly effective in dewatering fine particles, which is a common challenge in mining operations. By spinning at high speeds, centrifuges generate a force that separates the solid particles from the liquid, resulting in a drier product that is easier to handle and transport. This process is crucial for improving the efficiency of downstream processes such as smelting and refining.

Classification and Extraction of Valuable Metals

Another significant application of centrifuges in mining is in the extraction of precious metals like gold and platinum. These metals are often found in low concentrations within ore, making their extraction a complex and costly process. Centrifuges are used to separate these valuable minerals from the waste material, increasing the yield and purity of the extracted metals.

Waste Water Treatment

Furthermore, centrifuges are instrumental in environmental management within the mining industry. They help in the treatment of wastewater generated during mining activities. By removing suspended solids and other contaminants, centrifuges ensure that the water is clean enough to be discharged back into the environment or reused in the mining process, thus promoting sustainability.

In conclusion, GN centrifuges have become an indispensable tool in the mining industry. Their ability to efficiently separate solids from liquids, extract valuable minerals, and treat wastewater makes them a versatile and essential piece of equipment. As technology continues to advance, the role of centrifuges in mining is likely to expand, further enhancing the industry’s productivity and environmental stewardship.
