?Abington Wastewater Treatment Plant- Biosolids Management Report. This study took a holistic approach to biosolids management decision making. This residential community in the Philadelphia suburbs had been plagued with odor complaints and escalating costs. The comprehensive study evaluated digester operation and recommended operating and mechanical changes, evaluated bench test results of various dewatering equipment, identified and evaluated end use and disposal alternatives, conducted an odor audit and conceptual design of odor control equipment, estimated costs for digestion, dewatering and end use of the biosolids. Some questions that were addressed in the report were: Does the cost of digestion offset the cost of downstream processing and end use or disposal? How can we eliminate odor complaints from the neighbors? Which is better: belt press or centrifuge dewatering? A paper was co-authored with the client and presented at the 2000 WEF Residuals and Biosolids Specialty Conference. |
