Sludge dehydration decanter X series

centrifugalhorizontal

Up to 10% less sludge thanks to innovative scroll-free technology
Increased efficiency: lower energy and polymer consumption
Maximum dewatering with over 99% separation efficiency and higher throughput

Sewage sludge dewatering offers enormous potential savings for the operators of sewage treatment plants. The costs of transport and disposal of the dewatered sewage sludge frequently make up 80% of operating costs.

Depending on the capacity of the plant, 1% more dry substance in the dewatered sewage sludge can represent cost savings in the five- to six-digit range.
Sewage Sludge Dewatering the New Way – Xtra Performance With Less Consumption

Flottweg has developed a unique centrifuge concept specifically for high-degree dewatering of sewage sludge: the Flottweg X Series.

Flottweg X Series: the Most Economical Solution for Your Sewage Sludge Dewatering

Xtra dewatering performance: Up to 10%* less sludge volume due to up to 2% higher total dry solids in dewatered sludge.
Xtra polymer savings: Up to 20%* less flocculant needed.
Xtra energy savings: Up to 20%* lower energy consumption.
Xtra clean: The separation degree is greater than 99%.
Xtra capacity: Up to 15%* more throughflow.

The Secret of the Xelletor System: A Scroll With No Scroll Body

On the hunt for maximum separation efficiency, our engineers and technicians continually and radically question our existing centrifuge concept. Inspired by the lightweight construction of high-performance sports cars and motorcycles, they came up with the idea of a novel centrifuge design. The heart of the new design, the rotor and decanter scroll, were redesigned from the ground up.
