At the recently concluded IE EXPO CHINA 2025, GN Separation garnered significant attention, successfully forging new business collaborations and facilitating in-depth technological exchanges with both familiar and new industry contacts. The event served as an ideal platform for GN Separation to highlight its cutting-edge equipment designed specifically for environmental water treatment and solid waste management.

During the exhibition, GN Separation showcased three flagship products: the Solids Vacuum Pump, the Fully Hydraulic Decanter Centrifuge, and the 3 Phase Decanter Centrifuge. Each of these devices was engineered to tackle pivotal challenges in environmental engineering, spanning municipal sludge dewatering to intricate oil-water-solid separations.

Solids Vacuum Pump: A Multi-Faceted Solution for Material Handling

The fully pneumatic Solids Vacuum Pump stood out as a groundbreaking innovation, renowned for its reliable and efficient handling of a wide array of materials. Its applications extend across municipal and industrial sectors, encompassing:

• Sewage Sludge Removal: Ideal for clearing sedimentation tanks in wastewater treatment facilities.
• Construction Slurry Transport: Efficiently managing heavy mud from construction sites.
• Solid Waste Disposal: Capable of conveying granular solids such as sand and powdered residues.

Designed for durability, the pump operates without any electrical components, ensuring safety in potentially explosive environments and reducing long-term maintenance expenses. Its ability to adapt to varying material densities and particle sizes renders it a versatile solution for dynamic waste streams.

Fully Hydraulic Decanter Centrifuge: A Customized Dewatering Solution

The Fully Hydraulic Decanter Centrifuge by GN Separation distinguishes itself from conventional electric dewatering centrifuges by dynamically adjusting torque based on the characteristics of the feed material, thereby optimizing performance across a range of solid contents. Its key advantages include:

• Adaptive Torque Control: Ensures consistent cake dryness across diverse sludge types.
• Maintenance-Free Hydraulic Gearbox: Eliminates the need for routine servicing, thus lowering operational costs over time.
• Explosion-Proof Design: Certified for use in hazardous environments, including oilfields and chemical plants.

These features position it as a top choice for municipalities and industries seeking reliable and cost-effective dewatering solutions.

3 Phase Decanter Centrifuge: Precision Separation for Complex Waste Streams

The 3 Phase Decanter Centrifuge addresses the escalating demand for advanced separation technologies in environmental applications. Engineered to separate light liquid, heavy liquid, and solid phases simultaneously, it excels in:

• Kitchen Waste Oil Recovery: Extracting edible oils from food processing byproducts.
• Oil-Water Separation: Enhancing the efficiency of wastewater treatment in industrial settings.
• Oily Sludge Treatment: Recovering oil from contaminated sludge in refineries and petrochemical facilities.

By minimizing waste volume and recovering valuable resources, this centrifuge supports the principles of a circular economy while ensuring compliance with stringent environmental regulations.

Strategic Collaborations: Forging Alliances with Industry Pioneers

Beyond product demonstrations, GN Separation’s team engaged in comprehensive discussions with visitors, exploring potential partnerships in emerging markets and research endeavors. The company’s dedication to innovation was further emphasized through collaborations with universities and R&D institutions, focusing on the development of sustainable separation technologies.
