What is the primary function of an aerator in water treatment?

• A. To cool down the water
• B. To increase oxygen transfer to enhance water quality
• C. To filter out solid particles
• D. To remove harmful chemicals

Answer: (B)

The primary function of an aerator in water treatment is to increase oxygen transfer to enhance water quality. Aerators introduce air into the water, which facilitates the exchange of gasses, specifically adding oxygen to the water. This process is crucial because oxygen supports the growth of beneficial aerobic bacteria that help break down organic matter and other contaminants in the water. By improving the dissolved oxygen levels, aerators enhance the biological processes that contribute to the purification of water, thereby improving overall water quality for consumption and environmental discharge. The other functions mentioned in the options do not directly relate to the core purpose of an aerator. For instance, cooling down water, filtering out solid particles, and removing harmful chemicals involve different processes and equipment specifically designed for those tasks, such as chillers, filters, and chemical treatment systems.
