wastewater treatment facility

what does it do?
The Baton Rouge Refinery and the adjacent Chemical Plant each have wastewater treatment facilities that treat process wastewaters received from more than 50 miles of piping.

how does it work?
Primary treatment process consists of solids removal and neutralization which prepares the wastewater for biological treatment. 

Secondary treatment is the biological degradation of soluble organic compounds by microorganisms, commonly referred to as the “bugs.” 

After biotreatment, the microorganisms are separated from the water in a final clarification process, and the water is sampled as it is eventually discharged into the Mississippi River.

far better than the permitted limits
The Baton Rouge Refinery and the Chemical Plant both have an excellent compliance record. The outflow to the Mississippi River not only meets the standards set by the Louisiana Department of Environmental Quality (LDEQ) but is far better than the permitted limits.
