Which risk increases when dissolved molecular oxygen concentration drops in wastewater treatment?

💡 Explanation

Anaerobic conditions promote sulfate reduction because sulfate-reducing bacteria use sulfate rather than oxygen as a terminal electron acceptor; therefore, sulfide production increases, rather than nitrification via aerobic bacteria reducing sludge volume in oxygen-rich conditions.
