Slash operating costs for sludge dewatering with this centrifuge
Flottweg
The new Xelletor series decanter centrifuge (photo, p. 68) is said to provide better sludge-dewatering performance with lower energy consumption. The rotor, and especially the scroll, have a design never seen before. Consumption of polymer flocculant is significantly reduced in the Xelletor series thanks to an entirely new intake configuration. Depending on sludge quality, the centrifuge can save about 20% on energy while providing significantly better performance over traditional systems, says the company. Additional benefits include: more power, which increases throughput by up to 15%; drier cake, which can reduce the volume of biosolids by as much as 10%; and reduced operating costs by 20% due to lower energy consumption and polymer consumption.
