Aeration process is efficiently used to remove

Correct option is B

The aeration process is primarily used to remove volatile organic compounds (VOCs) from water or air. During aeration, water is exposed to air, allowing VOCs, which are highly volatile, to evaporate into the atmosphere. This process is not efficient for removing persistent organic pollutants (POPs), metals, or inorganic ions, which generally require different treatment processes.
Information Booster: 1. Volatile Organic Compounds (VOCs): Substances that can easily evaporate and are effectively removed through aeration.
2. Persistent Organic Pollutants (POPs): These are not effectively removed by aeration due to their stability and low volatility.
3. Metals and inorganic ions: Require specialized chemical treatments like precipitation or ion exchange for removal.
4. Aeration is often used in wastewater treatment plants to improve water quality by removing gases like carbon dioxide and VOCs.
5. Aeration also helps in increasing dissolved oxygen levels in water, supporting aquatic life.
6. It's a widely used technique in both water and wastewater treatment industries.
