Which one of the following is an anaerobic process?

  • A.Trickling filter operation
  • B.Rotating biological contact
  • C.Sludge digestion
  • D.Activated sludge aeration

Answer: C

Correct answer: Sludge digestion

Digestion is carried out in a sealed tank by anaerobic organisms, ending in methanogenesis. The other three all depend on oxygen: a trickling filter draws air through its media, a rotating contactor lifts its biofilm into the air, and activated sludge is aerated deliberately.
