MISSION CRITICAL PROJECT No. 8:
INITIAL CONDITIONS:
The Anheuser Busch Carterville facility is one of the largest of its kind and one of the most advanced in north America. It has its own wastewater pre-treatment plant that has been operating since 1993, handling brewery process wastewater as well as local municipal flows. Typical treatment capacity is 2.5 to 3 mgd (i.e. Millions of gallons per day). The plant never had a permit violation. This Anheuser Busch brewery is located in Cartersville, Georgia, USA.
The plant included digester facilities and equalization basins frequently exposed to the toxic, flammable, and highly corrosive H2S (hydrogen sulfide gas) in the operating range of 500 and 2000 ppm. Because of the severe amount of H2S in these processess areas, significant corrosion quickly started to destroy the structural integrity of the concrete and created leakage problems. The initial corrosion prevention product applied when the structure was built, failed shortly after installation. In 1998, and after approximately five years of extensive research and coatings evaluations, Anheuser Busch decided to apply Warren Epoxy.
Due to the outstanding corrosion and structural integrity protection provided by the Warren Epoxy coating at the subject facility, this product has since been applied to other Anheuser Busch Wastewater plants and facilities nationwide.
