South Digester Improvements
Design-Build
Project Overview
This project consisted of preparing design documents and construction of emergency repairs to The City of Elmhurst Digester No. 2. The need for these improvements resulted from the failure of the existing cover.
Project Location
Elmhurst, IL
Project Scope
The South Digester cover was a spirally guided gasholder with outdated gas injection mixing equipment. The decision was made to replace the cover in kind, but to use the cover replacement as an opportunity to update the mixer to improve mixing, reduce grit deposition in the digester, promote better digestion performance, and reduce power consumption. Specifically, the linear mixer technology marketed by Ovivo was selected to replace gas injection.
