University of Mississippi Upgrades Wastewater System to Handle Variable Flows

Problem: The University of Mississippi needed to upgrade to its wastewater facility built in 1972 as a dual-basin extended aeration plant. Flows varied widely with swings in on-campus population, from near zero at the Christmas break to extreme flows during home football games. Solution: ESI converted one basin to a 0.75 mgd oxidation ditch (Lakeside Equipment), replacing the existing clarifier and recirculation pumping, upgrading the headworks and converting the other aeration basin to flow equalization. The Closed Loop Reactor process consists of reactors with a single feed for raw wastewater and return activated sludge. The simple racetrack configuration provides a straight-line
