FAQs on Water Treatment using Aeration & Activated Carbon Video Lecture - Environmental Engineering - Civil Engineering (CE)
| 1. What is aeration in water treatment? |  |
Ans. Aeration in water treatment is the process of adding air or oxygen to water in order to remove dissolved gases, such as volatile organic compounds (VOCs) and hydrogen sulfide. This is achieved by introducing air or oxygen into the water through various methods, such as diffusers or mechanical aerators. Aeration helps in improving the taste and odor of water, as well as removing harmful substances.
| 2. How does aeration contribute to water treatment? | |
Ans. Aeration contributes to water treatment by oxidizing and removing dissolved gases and volatile organic compounds from water. It helps in reducing the concentration of harmful substances, such as iron, manganese, and hydrogen sulfide, which can cause taste and odor issues. Additionally, aeration enhances the effectiveness of subsequent treatment processes, such as activated carbon filtration, by pre-treating the water and improving the overall water quality.
| 3. What is activated carbon in water treatment? | |
Ans. Activated carbon is a highly porous form of carbon that is commonly used in water treatment. It is derived from organic materials, such as coal or coconut shells, and has a large surface area that allows it to effectively adsorb contaminants from water. Activated carbon is used to remove organic compounds, chlorine, pesticides, and other harmful substances, improving the taste, odor, and overall quality of water.
| 4. How does activated carbon filtration work in water treatment? | |
Ans. Activated carbon filtration works by adsorbing contaminants from water onto the surface of activated carbon particles. As water passes through a bed of activated carbon, the porous structure of the carbon traps and immobilizes impurities, effectively removing them from the water. This process is highly effective in removing organic compounds, chlorine, volatile organic compounds (VOCs), and certain heavy metals, resulting in cleaner and safer drinking water.
| 5. What are the advantages of using aeration and activated carbon in water treatment? | |
Ans. The advantages of using aeration and activated carbon in water treatment include improved taste and odor of water, removal of volatile organic compounds (VOCs), reduction of harmful substances like iron and manganese, enhanced removal of chlorine and organic compounds, and overall improvement in water quality. Aeration helps in pre-treating water by removing dissolved gases, while activated carbon filtration further removes contaminants, providing clean and safe drinking water.
