A)as electricity to power air pumps for aeration
B)as electricity to illuminate UV lamps
C)as heat to run distillation equipment
D)as electricity to power hydraulic pumps for reverse osmosis
E)none of the above

Question

Quizplus · Accepted Answer

Most of the energy required for secondary wastewater treatment is consumed as electricity to power air pumps for aeration, which is necessary for the biological breakdown of organic matter in the wastewater. This process requires continuous aeration to maintain aerobic conditions for the bacteria, and the air pumps consume a significant amount of energy. The other options, such as UV lamps, distillation equipment, and reverse osmosis, may be used in tertiary treatment, but are not typically used in secondary treatment.
