GN Separation is pleased to announce the successful installation and commissioning of GN sludge dewatering decanter centrifuges at municipal sewage treatment plants (STP) in France. Relying on a strong and reliable local partner, the project has been completed smoothly, and the equipment is now operating stably with performance fully meeting the design expectations.
This project further strengthens GN’s presence in the European wastewater treatment market and demonstrates the reliability of GN decanter centrifuges in municipal sewage sludge dewatering applications.
The French sewage treatment plants handle domestic wastewater and generate large volumes of biological sludge. Efficient sludge dewatering is critical to reduce disposal volume, lower operating costs, and ensure compliance with environmental regulations.
To address these challenges, the end user selected GN decanter centrifuges as the core sludge dewatering equipment, based on their proven performance, robust design, and adaptability to varying sludge conditions.
Based on the actual sludge characteristics and required treatment capacity, GN Separation supplied horizontal decanter centrifuges specifically configured for municipal sewage sludge dewatering.
The GN decanter centrifuge applies high centrifugal force to continuously separate solids from liquid. Clarified liquid is returned to the treatment process, while dewatered sludge cake is discharged for transport or disposal. Adjustable bowl speed and differential speed allow the centrifuge to adapt to fluctuations in sludge concentration and flow rate, ensuring stable and efficient operation.
With the support of GN’s professional local partner in France, the installation and commissioning work was completed efficiently. The commissioning process included equipment installation, system checks, test runs with actual sludge, and fine adjustment of operating parameters.
The centrifuges are now running smoothly, achieving the expected dewatering performance, and have been highly recognized by the end users for their stability, efficiency, and ease of operation.
GN’s local partner in France has strong capabilities in installation guidance, commissioning, and maintenance of decanter centrifuges, providing reliable technical support and after-sales service. This local presence offers solid assurance for the long-term operation of GN decanter centrifuges in France and across Europe.
After commissioning, the GN decanter centrifuge system has delivered clear benefits, including:
Improved sludge dewatering efficiency
Reduced sludge volume and disposal costs
Stable continuous operation with low vibration and noise
Easy operation and maintenance for plant operators
The compact design also allows seamless integration into existing STP layouts without major civil modifications.
GN Separation has extensive experience supplying decanter centrifuges for municipal and industrial wastewater treatment projects worldwide, covering applications such as:
Municipal sewage sludge dewatering
Industrial wastewater sludge treatment
Oil sludge and high-solids waste streams
Environmental protection and recycling projects
With reliable equipment quality, flexible configuration, and strong local technical support, GN decanter centrifuges continue to gain recognition in the European market.
The successful installation and commissioning of GN decanter centrifuges in French sewage treatment plants once again proves GN Separation’s technical strength, product reliability, and ability to work closely with local partners. GN remains committed to providing efficient, stable, and sustainable sludge dewatering solutions for wastewater treatment plants worldwide.
