In the field of modern wastewater treatment, industries face increasing pressure to reduce environmental impact while improving operational efficiency. Whether in municipal sludge handling, chemical separation, food production waste, or mining tailings, choosing the right dewatering solution is critical. Decanter centrifuges have become a trusted technology — compact, continuous, and highly effective.
As a leading manufacturer of separation equipment, GN Separation offers high-performance decanter centrifuges designed for complex industrial challenges. Our machines are widely used in wastewater treatment, chemical processing, food industry waste, and mining slurry management, delivering consistent results even in harsh environments.
High-Efficiency Dewatering with a Compact Footprint
Decanter centrifuge separates solids and liquids using high-speed rotation — a process that’s especially efficient for sludge generated after biological or chemical treatment. Compared to traditional dewatering methods such as filter presses, drying beds, or belt presses, centrifuges offer continuous operation, smaller space requirements, and less manual labor.
This leads to lower operational costs, faster processing times, and easier system integration. Whether for municipal sludge or industrial effluent, GN centrifuges deliver stable performance with minimal maintenance.
Built for Tough Jobs: Materials and Precision
Durability starts with design. GN Separation uses high-grade stainless steel, either centrifugal cast or forged, to build the bowl and screw — the core components of the centrifuge. Tungsten carbide hard alloy protection is applied to wear parts, extending service life in abrasive or corrosive conditions such as oily sludge, mining waste, or chemical residues.
To ensure top-tier precision, we use advanced CNC lathes, vertical machining centers, and gantry milling machines. This level of machining accuracy ensures optimal balance, tight tolerances, and long-term reliability.
We go one step further by applying high-speed dynamic balancing to both the screw and the bowl — not just at low speed, but at actual working speed. This reduces vibration, enhances safety, and increases bearing life under real operating conditions.
A Versatile Solution Across Industries
GN’s decanter centrifuges are trusted by global customers in wastewater treatment plants, oil refineries, food production lines, and mineral processing facilities. With energy-efficient drives, PLC-based automation, and modular installation options, our systems are easy to integrate into new or existing treatment processes.
Whether you’re separating sludge from a food plant, recovering water from tailings, or treating chemical waste, GN centrifuges offer a scalable and sustainable solution.
