GN Separation recently completed the manufacturing and shipment of a sludge dewatering centrifuge package to an overseas environmental protection company. This project demonstrates GN’s capability to deliver reliable and efficient sludge treatment solutions for international wastewater treatment applications.
The package is designed to support the client’s requirements for municipal and industrial sludge dewatering, ensuring stable performance, reduced sludge volume, and compliance with environmental standards.
Overview of GN Dewatering Decanter Centrifuge (T Series)
The core equipment in this project is the GN Dewatering Decanter Centrifuge (T Series).
GN dewatering decanter centrifuge is a T series decanter centrifuge with a beach angle of 8.5 degrees, specifically designed for sludge dewatering and thickening applications.
Thanks to its optimized structural design, the T series centrifuge is widely used in:
-
Municipal wastewater treatment
-
Industrial wastewater treatment
-
Environmental protection projects
Working Principle and Application
The GN T series decanter centrifuge is ideal for materials with:
-
Large particle size
-
High density difference between solid and liquid
-
Low viscosity
-
High concentration
For sludge containing fine particles, flocculants are typically added to aggregate fine solids into larger particles before entering the centrifuge. This significantly improves separation efficiency and dewatering performance.
Typical Applications
GN dewatering decanter centrifuge is suitable for a wide range of industries and materials, including:
-
Municipal sewage and river sludge
-
Food and organic wastewater
-
Oily sludge and oil sand separation
-
Drilling mud and construction slurry
-
Mining and mineral processing wastewater
-
Chemical and pharmaceutical wastewater
-
Printing and dyeing wastewater
-
Aquaculture wastewater
It is also widely used for solid-liquid separation of materials such as:
-
Calcium carbonate, bentonite, silica
-
Titanium dioxide, barium sulfate
-
Kaolin, aluminum hydroxide
-
Various industrial slurries and fine particles
