Denitrification of high strength nitrate bearing acidic ...

Nitrate, containing ,acidic, wastewaters are generated in nuclear fuel cycle operations. These waters are often neutralized prior to either storage or biological treatment. In this study, treatment of high strength ,nitrate, bearing ,acidic, waters was investigated in a sequencing batch reactor. A six liter reactor was inoculated with activated sludge and operated in sequencing batch reactor mode by...

Ammonia must first be oxidized to ,nitrate,; ,nitrate, is then reduced to nitrogen gas. These reactions require different environments and are often carried out in separate areas in the ,wastewater, treatment system. The first step in the process, conversion of ammonia to nitrite and then to ,nitrate,, is called nitrification (NH 3 NO 2 + NO 3).
