The United States first WWTP that is both ecologically and economically sustainable

Watercycle reference

Reducing impact of wastewater treatment on Clemens Foods profit margin, while complying with effluent demands. 

The nation’s first WWTP that is both ecologically and economically sustainable. Clemens Food wastewater treatment plant in Coldwater, MI sets a new standard in operating costs for the meat industry.

The treatment costs are significantly lower (over half) than the average US slaughterhouses.

The Coldwater WWTP features state-of-the art flotation clarifiers, exceptionally energy efficient aeration, non-chemical pretreatment, COD-NH4-NO3-MLSS controlled processes, fat recovery, protein recovery, effluent re-use while ensuring that the remainder is not discharged cleaner than need be.

Results:

  • Protein and fat are recovered (revenue source), rather than decomposed (costs)
  • Effluent is treated to allow (partially) re-use
  • Fully automated system to ensure maximum performance minimizing labor requirement
  • Designed for minimal operating costs. Over half the costs compared to conventional systems currently in operation at most US slaughterhouses
