Advanced sludge dewatering for sewage treatment plants
Sewage treatment plants face high costs due to the transport and disposal of sewage sludge. Efficient dewatering techniques can drastically reduce these expenses by increasing the dry substance percentage in dewatered sludge.
Reduce sludge volume and energy consumption
The Flottweg Xelletor Decanter is a cutting-edge centrifuge designed specifically for high-grade dewatering of sewage sludge. Unlike previous models, the Xelletor features a scroll with no scroll body, leading to maximum compression and separation efficiency. The innovative design reduces sludge volume by up to 10%, requires up to 20% less energy, and cuts down flocculant usage by up to 20%. The system’s sealed construction minimizes odors and sludge aerosols. The Xelletor integrates features like the Flottweg Recuvane® for energy recovery and the powerful Flottweg Simp Drive®. It offers automated regulation and real-time monitoring of bowl and differential speed. Suitable for extensive on-site testing or as part of complete plant solutions, the Xelletor system can also be retrofitted to existing Flottweg decanters. Dimensions and weights vary by model: X4E (3500x1100x1000mm, 2760kg), X5E (4100x1500x1200mm, 5030kg), and X7E (4800x1700x1400mm, 8200kg).
