Q. In a water supply scheme, for what purpose aeration is carried out?

A
to remove taste and odour
B
for complete elimination of colloidal matter
C
for killing pathogenic bacteria
D
for coagulation
Solution:

Aeration helps prevent taste and odour problems by ensuring that oxygen concentrations remain high enough throughout the entire water column to prevent conditions of little or no oxygen (anaerobic). Aeration also helps prevent the release of phosphorus from sediments. This limits algae growth and reduces the amount of plant material present to ultimately die and decompose.
