Faced with an aging wastewater treatment facility (WWTF), Wheaton College in Norton, Mass., needed a master plan that would resolve permit requirements, improve reliability and efficiency, and plan for future capacity needs. Meanwhile, however, interim solutions were called for to optimize treatment while reducing operating costs. During 50 years of operating an extendedaeration package plant, Wheaton College had never needed to thicken its waste activated sludge before it was hauled away. But as flows and loads to the plant and the resulting sludge-hauling costs increased, the college looked for a process modification to save money. The resulting do-ityourself settling and decanting system uses simple components and reduces the WWTF's sludgehauling costs by as much as 50 percent per year. The system includes a live-feed video camera that enables operators to visually monitor and control the decanting process from anywhere there is Internet access - even the living room. Source
