Which set of conditions will most effectively removed nitrogen containing compounds from wastewater to reduce eutrophication?

Question

Quizplus · Accepted Answer

Aerobic conditions with the addition of nitrifiers can convert ammonia to nitrate, which is less harmful but still contributes to eutrophication. Denitrifiers can then convert nitrate to nitrogen gas, which is non-toxic and can be safely released into the atmosphere. However, both processes require oxygen, which can limit the efficiency of the treatment. Anammox bacteria, on the other hand, can convert ammonia to nitrogen gas directly, without the need for oxygen. This makes them ideal for treating wastewater under aerobic conditions, as they can lower the oxygen demand and improve the overall performance of the system. Therefore, the best choice is C, which combines nitrifiers and anammox bacteria under aerobic conditions.
