Q: What is the correct answer for CUET UG Biology Q11?

The correct answer is a. The correct sequence of sewage treatment is:1. Primary treatment involves physical removal of large and small particles through filtration and sedimentation. This begins with the removal of floating debris and grit (B).2. The primary effluent is then passed into large aeration tanks and agitated mechanically (D) to allow the growth of aerobic microbes.3. Aerobic microbes (flocs) consume organic

The correct sequence of sewage treatment is:1.  Primary treatment involves physical removal of large and small particles through filtration and sedimentation. This begins with the removal of floating debris and grit (B).2.  The primary effluent is then passed into large aeration tanks and agitated mechanically (D) to allow the growth of aerobic microbes.3.  Aerobic microbes (flocs) consume organic matter, which reduces the BOD of the sewage (A).4.  Once BOD is reduced, the bacterial flocs are allowed to sediment in a settling tank (C).5.  The effluent after secondary treatment is released into natural water bodies (E).So, the sequence is B-D-A-C-E.
