Bag filters are used for removal of pollutants from

Options

A. Exhaust emissions
B. Effluent water
C. sewage water
D. Both B and C

Answer

**Step-by-Step Solution:**

1. **Understanding Bag Filters**: Bag filters are devices used to remove pollutants from air or gas streams. They are commonly employed in various industrial applications to control air pollution.

2. **Identifying the Pollutants**: The question asks about the removal of pollutants from specific sources: exhaust emissions, effluent water, and sewage water. We need to analyze each option to determine where bag filters are applicable.

3. **Exhaust Emissions**: Exhaust emissions refer to the gases and substances released into the atmosphere from the combustion of fuels. This includes emissions from vehicles, industrial processes, and power plants. Bag filters are effective in capturing particulate matter from these emissions.

4. **Effluent Water**: Effluent water is wastewater that is discharged from industrial or domestic sources. It typically contains various pollutants, but bag filters are not primarily used for treating water; they are designed for air filtration.

5. **Sewage Water**: Sewage water is a type of wastewater that comes from households and communities. Similar to effluent water, it contains organic and inorganic pollutants. Bag filters are not typically used for sewage treatment.

6. **Conclusion**: Based on the analysis, bag filters are specifically used for the removal of pollutants from exhaust emissions, as they target airborne particulates. Therefore, the correct answer to the question is that bag filters are used for the removal of pollutants from exhaust emissions.

**Final Answer**: Bag filters are used for the removal of pollutants from exhaust emissions.
