At the time, the Delphos plant was the largest Ovivo MBR facility in the world.
DESCRIPTION
The City of Delphos evaluated several treatment options, including an oxidation ditch, when considering how to upgrade their aging trickling filter facility. Some of the factors considered in the decision making process included current and future permit compliance issues, fluctuating loading conditions, and treatment capacity. The City selected an Ovivo MBR System. Since startup in September 2006, the plant has already been put through its paces and demonstrated its capability to reliably meet permit limits.
