New centrifuge is designed for biosolids dewatering
Xelletor (photo) is a new open-scroll centrifuge technology for water treatment application. Optimized for dewatering of biosolids, the Xelletor’s new design enables higher capacities, drier cakes and lower polymer consumption, says the company. Drier cakes mean lower transportation costs, and the Xelletor can provide cakes with 10% lower volume by delivering 2% higher total dry solids. Depending on the capacity of the plant, a 1% increase in dry substance in the dewatered sewage sludge can represent significant cost savings. Xelletor also delivers polymer cost savings by using up to 20% less polymer. Furthermore, says the manufacturer, 20% lower energy consumption is expected with Xelletor, as well as higher capacity with up to 15% more throughflow.
