Denitrification in sewage treatment systems requires

Question

Quizplus · Accepted Answer

Denitrification is a process where nitrate (NO3-) is converted to nitrogen gas (N2) in an anaerobic environment. This process requires the absence of oxygen (O2). Therefore, Option C is the correct choice. Option A (the bubbling of oxygen into waste sewage) is incorrect because denitrification requires the absence of oxygen. Option B (the addition of water to waste sewage) is not directly related to denitrification. Option D (an aerobic environment) is incorrect because denitrification requires the absence of oxygen.
