The electrostatic precipitator is used for removing particulate matter from

Options

A. Exhaust of the thermal power plant
B. Exhaust from the automobiles
C. Industrial effluents
D. Kitichen wate

Answer

To solve the question regarding the use of an electrostatic precipitator, we will follow these steps:

### Step-by-Step Solution:

1. **Understand the Function of Electrostatic Precipitators**: Electrostatic precipitators are devices used to remove particulate matter from gases. They work by charging the particles and then collecting them on oppositely charged plates.

2. **Identify the Context**: The question asks from where the electrostatic precipitator removes particulate matter. We need to evaluate the options provided.

3. **Evaluate Each Option**:
- **Option A: Exhaust of thermal power plants**: Thermal power plants produce a significant amount of particulate matter in their exhaust, and electrostatic precipitators are commonly used in these plants to remove up to 99% of the particulate matter.
- **Option B: Exhaust from automobiles**: While automobiles do produce particulate matter, they typically use different technologies, such as catalytic converters and filters, rather than electrostatic precipitators.
- **Option C: Industrial effluents**: Industrial effluents may contain various pollutants, but electrostatic precipitators are not primarily used for liquid effluents.
- **Option D: Kitchen waste**: Kitchen waste does not involve the use of electrostatic precipitators, as it is not a gas phase that needs particulate removal.

4. **Conclusion**: Based on the evaluation, the electrostatic precipitator is primarily used for removing particulate matter from the exhaust of thermal power plants. Therefore, the correct answer is **Option A**.

### Final Answer:
The electrostatic precipitator is used for removing particulate matter from the **exhaust of thermal power plants**.
