Question

The device which can remove particulate matter present in the exhaust from a thermal power plant is :
(1) Catalytic Convertor (2) STP (3) Incinerator (4) Electrostatic Precipitator

Accepted Answer

Correct Answer: D — Electrostatic PrecipitatorStep-by-step Solution:An Electrostatic Precipitator (ESP) removes particulate matter (fly ash, dust, soot) from industrial exhaust gases. It works by charging the particles using electrodes and then collecting them on oppositely charged plates. It can remove up to 99% of particulate matter and is widely used in thermal power plants.Why other options are wrong:Catalytic Convertor — removes gaseous pollutants such as CO, NOx, and unburnt hydrocarbons from vehicle exhaust; not used for particulate removal in power plants.STP (Sewage Treatment Plant) — treats liquid wastewater/sewage; unrelated to air pollution control.Incinerator — burns solid waste at high temperatures; it generates exhaust rather than removing particulate matter from exhaust.Key Concept: Electrostatic Precipitator — removes particulate pollutants from air/exhaust by electrostatic attraction. It is the most effective device for controlling particulate air pollution from industries.

The device which can remove particulate matter present in the exhaust from a thermal power plant is : (1) Catalytic Convertor (2) STP (3) Incinerator (4) Electrostatic Precipitator
