Question

Quizplus · Accepted Answer

Biological nutrient removal (BNR) is a wastewater treatment process that mainly targets the removal of nitrogen and phosphorous from wastewater. During BNR, microorganisms break down organic materials in wastewater to carbon dioxide, water, and nitrogen gas. Therefore, the ultimate conversion of organic materials in wastewater during BNR is into nitrogen, water, and carbon dioxide (Choice B).
