The Xelletor series of decanter centrifuges from Flottweg Separation Technology reduces the consumption of polymers and increases throughput, saving on disposal costs while maintaining a separation efficiency greater than 99 percent. It reduces the volume of biosolids by producing a drier cake. It offers fully automatic control of the bowl and differential speeds, even when there are fluctuations in the feed, using the Simp Control. Optional automatic flocculant dosing with real-time monitoring also helps reduce polymer consumption. It has closed construction, providing a shield against noise and sewage sludge aerosols. 859-448-2331; www.flottweg.com
