Clean water is becoming an increasingly valuable resource, which is why the importance of urban sewage and drinking water treatment continues to grow worldwide. Sludge generated during water and wastewater treatment must be separated and reduced as efficiently as possible to minimize disposal costs and environmental impact. Continue reading

Some Operational Recommendations for Decanter Centrifuges
To achieve optimal separation performance and ensure stable, long-term operation of the decanter centrifuge, GN Separation provides the following operational recommendations:
1. Maintain Stable Feed Conditions
To ensure stable and continuous operation, it is essential to keep the feed flow rate, solids concentration, and temperature as consistent as possible. Stable feed conditions allow the decanter centrifuge to operate smoothly, ensuring constant liquid clarity and solids discharge, while also enabling downstream equipment to function reliably and maintaining overall system stability.
The Thickness of Liquid-Ring Layer in Decanter Centrifuge Operation
The thickness of the liquid-ring layer is a critical operating parameter in decanter centrifuge optimization. It directly influences the effective settling volume inside the bowl and the length of the drying (beach) zone, thereby affecting the overall sludge dewatering performance. Continue reading
Key Considerations for Selecting a Decanter Centrifuge
Selecting an appropriate decanter centrifuge not only helps resolve production challenges and improve operating efficiency, but also reduces overall production costs and operational risks. The following factors should be carefully considered during the selection process:
