Advanced sludge dewatering for sewage treatment plants
Optimize sludge dewatering with a centrifuge that enhances separation efficiency, reduces operational costs, and minimizes environmental impact.

The Xelletor Decanter Centrifuge from Flottweg redefines sludge dewatering efficiency for applications ranging from municipal sewage treatment to industrial waste management. Utilizing a novel scroll design without a traditional scroll body, it ensures maximum separation efficiency with minimal wear. Capable of processing various slurries, the Xelletor achieves up to 15% more throughput and reduces sludge volume by up to 10%. Fully automated, it integrates seamlessly into continuous operations, supported by real-time monitoring and automatic flocculant dosing. Energy consumption is reduced by up to 20% with the Flottweg Recuvane® technology. Built with robust wear protection, it promises a long service life, minimizing maintenance costs. Ideal for environments requiring durable and efficient separation, it’s available in various customizable configurations to match specific processing needs.
