Challenge: The Frackville Area Municipal Authority sought to upgrade and improve its aerobic digestion system. Solution: The engineering firm proposed retrofitting the two existing aerobic digestion tanks with a new aerobic digestion system to minimize operating and capital costs and provide maximum mixing and aeration efficiency of waste-activated sludge. Conclusion: The new system has improved digestion performance and substantially reduced energy usage without creating a need for additional tank volume. [ABSTRACT FROM AUTHOR]
