Economic solution for sludge dewatering
The new Xelletor Series of sludge-dewatering decanters is designed to dry sludge more efficiently and reduce disposal costs for treatment-plant operators. The decanter features a uniquely designed rotor and scroll, and consumption of polymer flocculant is significantly reduced, due to an entirely new intake configuration. Depending on sludge quality, the device can save about 20% on energy and polymer consumption, increase throughput by up to 15% and reduce the volume of biosolids by as much as 10%, according to the manufacturer. The Series’ extra-deep pond concept further contributes to energy savings. Compared to conventional high-performance centrifuges, the Xelletor can achieve a 2% increase in dry-matter content, reducing overall sludge volume. Booth 6439 — Flottweg SE, Vilsbiburg, Germany
