How does the Blue Plains sludge treatment system work?
The system generates high quality sludge that is used as soil amendments (200,000 tons/year). A portion of the sludge is processed in an anaerobic digestion system which generates 10 MW of electricity that is used elsewhere at the treatment plant. The original Blue Plains facility opened in 1937 as a primary treatment facility.

With the $950 million project complete, Blue Plains will produce effluent with some of the lowest levels of nitrogen in the country. At 4 mg/L, it is extremely low, and is considered near the limit of conventional treatment technology.
What is Blue Plains doing about nitrogen?
Blue Plains was the first plant in the region to achieve that goal. Furthermore, in every year since the full-scale implementation of the biological nitrogen removal (BNR) process was completed in 2000, Blue Plains has every year successfully achieved and exceeded that goal of a 40 percent reduction.
