Flottweg Separation Technology’s Xelletor series of decanter centrifuges uses a new intake configuration to reduce the consumption of polymers and increase throughput, saving on sludge 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 Flottweg 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
