Del Monte Foods Saves Millions with BlueInGreen's SDOX® Solution

Introduction

Plant managers at Del Monte Foods in Siloam Springs, Ark. utilized a 14 million gallon facultative lagoon to provide treatment before applying the effluent on 500 acres of land nearby. However, the facultative lagoon was unable to meet the municipal pretreatment permit requirements, resulting in surcharges of $450,000 per month.


Project Goals

  • Meet Dissolved Oxygen (DO) Requirements
  • Reduce Operating Costs

Method

After reviewing possible treatment options, project engineers selected BlueInGreen’s SDOX® solution. In order to provide an aerobic treatment process, the SDOX® effectively saturated a sidestream of wastewater with dissolved oxygen before returning it to the lagoon for rapid liquid-to-liquid mixing.

Results

After installation and system optimization, the SDOX® reduced biochemical oxygen demand (BOD) and total suspended solids (TSS) levels to comply with local permit requirements, allowing the facility to avoid future penalties from the city. As a result, municipal surcharges dropped from $450,000 per month to $19,000 per month.

Monthly Surcharges

Dollars in thousands.

AFTER INSTALLING THE SDOX®, DEL MONTE WAS ABLE TO MEET PERMIT REQUIREMENTS AND SAVED $5 MILLION EACH YEAR AS A RESULT. 


Conclusion

Ultimately, the project saved Del Monte Foods approximately $5 million in annual surcharges, providing a complete project payback, with additional return on investment expected in the near future. The savings afforded by the SDOX® will also position the facility to remain in environmental compliance for years to come.
