What do wastewater treatment facilities primarily depend upon for the breakdown of pathogenic organisms and organic materials in wastewater?
A)lots of chlorine bleach
B)decomposers and detritus feeders
C)the neutralizing effects of high levels of oxygen
D)large amounts of antibiotics and disinfecting chemicals

Question

Quizplus · Accepted Answer

Wastewater treatment facilities primarily depend upon decomposers and detritus feeders for the breakdown of pathogenic organisms and organic materials in wastewater. These organisms break down organic matter into simpler compounds, making it safe for discharge into the environment. Chlorine bleach, antibiotics, and disinfecting chemicals are used for secondary treatment and disinfection, respectively, but they are not the primary method for breaking down organic matter. The neutralizing effects of high levels of oxygen are important for the aerobic digestion of organic matter, but they are not the primary method for breaking down pathogenic organisms.
