The Archer Western-Stantec design-build team has been selected to complete Phase 1 of a Class A Process Optimization for Wastewater Energy Recovery project and wastewater treatment plant upgrades for the city of Chattanooga Moccasin Bend Environmental Campus. Archer Western Construction will serve as the lead contractor while Stantec will lead design and engineering.This progressive design-build project is expected to incorporate a thermal hydrolysis process facility, anaerobic digestion upgrades, and conversion of a high purity oxygen facility to a membrane aerated biofilm reactor. Upon completion, the project will be the largest MABR facility in the world. MABR is an energy-efficient, intensified nutrient-removal process that will allow the city to utilize its existing tanks rather than having to build new ones—while meeting future nutrient limits in effluent discharged from the Moccasin Bend Environmental Campus.
