FACILITY SAVES MILLIONS WITH AERATION  

DEL MONTE FOODS

 

Technology: SDOX

Application: Post-Aeration 

Location: Arkansas

Owner: Del Monte Foods

Goals:

  • Meet DO Requirements
  • Reduce Operating Costs

 

INTRODUCTION

Plant managers at Del Monte Foods in Northwest Arkansas 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. 

 

METHOD

After reviewing possible solutions, project engineers selected BlueInGreen’s SDOX system. 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. 

 

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

 

 

 

RESULTS

After installation and optimization, the SDOX reduced BOD and TSS levels to comply with 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.

CONCLUSION

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