Efficient Wastewater Treatment with GN Separation’s Dewatering Decanter Centrifuge

At GN Separation, we pride ourselves on providing advanced solutions for wastewater treatment, and our dewatering decanter centrifuge is a prime example. Designed specifically to meet the rigorous demands of both municipal and industrial wastewater treatment, our T series decanter centrifuge stands out in terms of performance, reliability, and efficiency.

Why Choose GN’s T Series Dewatering Decanter Centrifuge?

The GN T series dewatering decanter centrifuge, with a beach angle of 8.5 degrees, is specifically engineered for dewatering and thickening applications. It excels in handling various materials, including those with large particle sizes, significant density differences between solid and liquid, low viscosity, high concentration, and high treatment capacity. The T series ensures higher dryness in the discharged solids compared to traditional methods.

One of the key advantages of our decanter centrifuge is its versatility. It is effectively used in a wide range of applications, such as:

  • Drilling Mud and Oily Sludge
  • Environmental Protection Sewage
  • Cutting Fluid and Sand Washing Water
  • Mineral Washing and Industrial Wastewater
  • Municipal Sewage and River Sludge

Advanced Engineering for Optimal Performance

The GN T series decanter centrifuge is built using high-quality materials and cutting-edge manufacturing techniques:

  • Durable Construction: The bowl and shaft caps are made from duplex stainless steel (SUS2205 or SUS2304), superior to SUS304 and SUS316 in terms of performance and corrosion resistance.
  • Enhanced Screw Design: The screw blade, formed by CNC equipment, offers higher slag conveying efficiency. The gradual change type screw blade improves the dewatering efficiency, making the solids drier.
  • Optimized Beach Angle and Pitch: This design separates the dewatering zone from the sedimentation zone, leading to clearer separated liquid and larger processing capacity.
  • Energy Efficiency: The deeper liquid pool design reduces kinetic energy loss, enhancing energy efficiency while maintaining high clarity in the discharged liquid.
  • Wear Resistance: The solid discharge port is equipped with a tungsten carbide sleeve for high wear resistance, ensuring long service life.
  • Convenient Adjustability: The overflow weir plate allows for flexible adjustment of the liquid pool depth to meet various material requirements.

Safety and Monitoring

Safety and operational efficiency are paramount in our designs. Our centrifuges come with comprehensive monitoring and alarm systems, ensuring automatic protection against overload, short circuit, and other operational anomalies. The system monitors parameters such as centrifuge speed, bearing temperature, vibration, and motor current in real-time, providing timely alerts for any abnormalities.
