Question:
Which equipment is most widely used for removing particulate matter present in industrial exhaust ?
Which equipment is most widely used for removing particulate matter present in industrial exhaust ?
Show Hint
It charges dust particles and collects them on plates.
Updated On: Nov 12, 2026
- Electrostatic precipitator
- Scrubber
- Filters
- Catalytic converters
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
Industrial exhausts such as those of thermal power plants carry particulate matter that must be removed.
Step 2: How the device works
An electrostatic precipitator gives dust particles a negative charge using high voltage electrode wires. The charged particles are attracted to grounded collecting plates and removed.
Step 3: Efficiency
It removes over 99 percent of particulate matter. Scrubbers mainly remove gases like \(\text{SO}_2\), and catalytic converters treat vehicle exhaust gases.
Step 4: Conclusion
The electrostatic precipitator is most widely used for particulate matter.
Final Answer:
The electrostatic precipitator is the most widely used device for removing particulate matter. \[ \boxed{\text{(A) }\text{Electrostatic precipitator}} \]
