Abstract

This research was undertaken to determine the feasibility of dewatering digested sludge using vacuum filters or centrifuges followed by land spreading as opposed to the present method of sludge hauling and disposal. The objectives of these experiments were to: 1 Determine whether the sludge from the Sioux Falls Wastewater Treatment Plant with the addition of a selected polymer could be dewatered by means of a vacuum filter. 2. Determine whether the sludge from the Sioux Falls Wastewater Treatment Plant with the addition of a selected polymer could be dewatered by means of a solid bowl centrifuge. 3. Establish capita costs for sludge dewatering and disposal by means of vacuum filtration, centrifugation and the existing method of lagoons and drying beds with land application.4. Establish operation and maintenance costs for sludge dewatering and disposal by means of vacuum filtration, centrifugation and the existing method of lagoons and drying beds with land application. 5. Compare the average annual costs of the three mentioned dewatering and disposal methods.
