2.0 MGD Two-Stage MLE Activated Sludge Wastewater Treatment System

We were hired by Koch Foods to design a new 2.0 MGD Two-Stage MLE Activated Sludge Wastewater Treatment System to meet newly mandated ELG limits which required them to reduce Total Nitrogen down to 150 mg/l.

The system included the following major system components:

  • Anoxic Reactor #1 with Jet aeration and mixing
  • Aerobic/Nitrification Reactor #2 with Jet aeration and mixing
  • Final Clarifier
  • UV Disinfection
  • Cascade Aeration
  • Automation and Controls
  • New Equipment Building with Lab and Office
