DuPont Biological Wastewater Treatment Facility

DuPont awarded Fluor the detailed design and procurement of a wastewater bio-treatment facility for its Victoria, Texas plant. The plant's new wastewater treatment complex treated hazardous wastes generated at the petrochemical plant and eliminated the need for deepwell disposal. The project also returned over three million gallons per day of clean, safe water to the surrounding environment.

Client's Challenge

The project was part of the $140 million Deepwell Elimination Program that DuPont was executing to deliver on its Texas 2000 Program and its Corporate Environmental Goal commitment to eliminate deepwell injection for hazardous waste. The program included 13 pretreatment projects at the Sabine River Works and Victoria Plant.

Fluor's Solution

Fluor was involved in all of these projects and provided program management. The first part of this project was the detailed design and procurement of a wastewater bio-treatment unit.

The second part was the derivative of PHA on the bio-treatment. It consisted of the following activities:

New vent header design from "B", CSM and acid eq. tank to the existing 10" vent header
New liquid lines to segregate "A" wastewater
Bio analyzers
Copper analyzers

There was segregation of hydrocarbon contained liquid with nitric acid contained liquid to avoid explosive liquid mixture.

Conclusion

The Victoria wastewater bio-treatment plant was successfully completed and operational in 2000.
