The City of Spring Hill Wastewater Treatment Plant in Spring Hill, Tennessee is experiencing increasingly long downtime due to maintenance needs on their existing dewatering belt filter presses, polymer blender, and sludge day tank which pushed them to pursue replacement centrifuge dewatering equipment. The existing building, designed to house presses, not centrifuges, was abandoned for a new building. The new dewatering facility will house two duty centrifuges with space for a third. The cake handling will be by screw conveyors offloading into a two-truck loadout facility with scales. Other aspects of this design include sludge density meters, polymer storage and blending, truck traffic routing, storm swale construction, and upgrades to sludge feeding and handling for the new dewatering facility. The existing facility is a 5 mgd Carrousel® Bardenpho® oxidation ditch plant with aerobic digestion. Current plans are to increase the capacity of the facility to 10 mgd with provisions for more. The resulting dewatering facility was designed to allow for easy expansion through increased operation and/or additional equipment. After this expansion, the new dewatering facility will no longer be a bottleneck in their facility, providing both a consistent return stream and a consistent product. This presentation will be focused on three aspects of centrifuge design and one of general design: Robustness, Redundancy Criteria, Accessibility, and the Unique Needs of Centrifuges. Those design aspects led, in part, from replacing the belt filter presses with centrifuges in the existing building to constructing a new facility. This presentation is for those that are interested in exploring new or rehabilitated dewatering facilities and specifically centrifuge facilities.
