SDOX REDUCES FOOTPRINT & COSTS OF REARATION

CHEESE PRODUCTION FACILITY

 

Technology: SDOX

Application: Rearation 

Location: Colorado

Goals: Meet DO Requirements | Minimize Plant Footprint 

 

INTRODUCTION

While constructing a new water treatment system, a cheese production facility was forced to redesign its industrial process in order to meet new state legislation, which called for a 6-mg/L dissolved oxygen requirement to the National Pollutant Discharge Elimination System (NPDS) permit. With limited space at the planned facility and a desire to minimize capital and operating expenses, the engineers began researching dissolution systems that could meet the DO requirements as well as fit within their facility’s blueprint.

 

METHOD

The majority of oxygen dissolution systems require a costly equipment, such as blowers and diffusers, as well as expensive infrastructure, such as concrete basins. Engineers at the plant selected BlueInGreen's SDOX® solution due to its sidestream technology. Because the oxygen is predissolved, the post-aeration can be accomplished in-pipe without the need for large concrete or steel structures. In addition to reducing the plant’s footprint, BlueInGreen’s system is also easy to install. Each skid-mounted SDOX unit comes fully equipped, including pump, motor, VFD, control panel with PLC and HMI, multiple operation modes and all associated piping, values and instrumentation.

 

THE FACILITY WAS ABLE TO MEET THE DISSOLVED OXYGEN REQUIREMENT WITHOUT ADDING ANY ADDITIONAL INFRASTRUCTURE.

 

RESULTS

After installing the SDOX and completing plant construction, the facility was able to meet the 6-mg/L DO requirement without adding any additional infrastructure. In addition to saving on construction costs, the facility also reduced operational costs. Unlike bubble diffusers, which allow oxygen to reach the service without being absorbed in stream, the SDOX features up to a 99 percent transfer efficiency rate, reducing oxygen usage, and power consumption.

 

CONCLUSION

Despite limited space in the new facility, the cheese production facility was able to complete construction at the new water treatment plant and consistently met the DO levels required by the NPDS permit. The SDOX also fit perfectly in the plant’s budget, reducing operational costs in both the short and long term.
