Question

While wastewater is in an activated sludge tank, much of the organic matter is
A) oxidized.
B) adsorbed to the floc.
C) incorporated into microbial cells.
D) oxidized, adsorbed to the floc, and incorporated into microbial cells.

Accepted Answer

In an activated sludge tank, the organic matter in wastewater is subject to various biological processes driven by microbial populations. These processes include oxidation, adsorption to the floc (aggregated microbial biomass), and incorporation into microbial cells. Therefore, the correct answer is D, as it encompasses all these possible mechanisms.
