Question

During wastewater treatment, the secondary treatment requires continual aeration to
A) suppress microbial growth.
B) select for anaerobic heterotrophs.
C) stimulate abiotic degradation.
D) increase microaerophilic filamentous bacteria.
E) maximize breakdown of molecules to CO2and nitrates.

Accepted Answer

Continual aeration during secondary treatment helps to maximize the breakdown of molecules to CO2 and nitrates through the process of aerobic respiration by aerobic heterotrophic bacteria. This helps to remove organic pollutants and nitrogenous compounds from the wastewater.
