Schreiber Foods Cuts Chemical Costs with BlueInGreen's CDOX® Solution

Introduction

At Schreiber Foods' wastewater treatment plant in Utah, mineral acids had been used for pH control in the past but were discontinued due to safety and handling issues. With an average daily flow of 250,000 gallons, the cheese and yogurt facility struggled to meet discharge permit requirements. Facility owners desired a safer, more cost-effective solution that would provide automatic control over process pH levels.


Project Goals

  • Reduce Carbon Dioxide (CO2) Usage

  • Provide Precise pH Control


Method

BlueInGreen’s CDOX® technology was sought out for its highly efficient process of automatic pH control and its ability to utilize process water as the carrier stream. BlueInGreen’s proprietary process makes it possible to deliver large quantities of gas in very small quantities of water – as much as 10 times less than the closest competitor. Because BlueInGreen provides a fully integrated, skid-mounted system, the unit was installed by plant staff with relatively little effort.

Results

After start-up and tuning of the CDOX® system, the Equalizing (EQ) basin effluent pH was brought under control in a pH range more conducive to microbial activity, automatically making adjustments for changes in water quality and flow rates. By reducing the amount of carbon dioxide needed for treatment, the facility saved over $57,000 in chemical costs alone in two consecutive years.


BLUEINGREEN’S CDOX TECHNOLOGY DEMONSTRATED EFFECTIVE PH CONTROL WITH FAST RESPONSE TO INFLUENT WATER QUALITY AND QUANTITY CHANGES.

Conclusion

In conclusion, BlueInGreen’s CDOX® technology demonstrated effective pH control with fast response to influent water quality and quantity changes at Schreiber Foods' cheese and yogurt facility. The process is highly efficient, having excellent mass transfer capabilities and near 100 percent utilization of vaporized gas. Combined with a fully-integrated control scheme that is unmatched in the industry, the CDOX® excels at carbon dioxide delivery.


BY REDUCING CARBON DIOXIDE USAGE, THE FACILITY SAVED OVER $57,000 IN TWO YEARS.
