Difficulty: EasyEnvironmental Pollution: Types, Causes and Control Measures

Match the environmental pollution control devices listed in List-I with their primary targeted pollutant or function in List-II:

  • Electrostatic PrecipitatorParticulate matter from industrial flue gases
  • Catalytic ConverterCarbon monoxide and unburnt hydrocarbons in vehicle exhaust
  • Wet ScrubberGaseous emissions such as sulfur dioxide (SO2SO_2)
  • IncineratorThermal disposal of hazardous solid and medical waste

Answer

Electrostatic Precipitator matches with Particulate matter from industrial flue gases; Catalytic Converter matches with Carbon monoxide and unburnt hydrocarbons in vehicle exhaust; Wet Scrubber matches with Gaseous emissions such as sulfur dioxide (SO2SO_2); and Incinerator matches with Thermal disposal of hazardous solid and medical waste.
Electrostatic Precipitators are designed to capture solid suspended particles from industrial flue gases. Catalytic Converters reduce vehicular exhaust emissions by converting carbon monoxide and unburnt hydrocarbons into less harmful compounds. Wet Scrubbers clean exhaust streams by dissolving gaseous pollutants like sulfur dioxide in liquid spray. Incinerators thermally break down solid hazardous and biological wastes.

Step-by-Step Solution

1
Match Electrostatic Precipitator with its primary application.
Electrostatic Precipitators trap charged particulate matter from flue gases.
High-voltage electrodes charge dust particles which collect on grounded plates.
2
Match Catalytic Converter with its targeted emissions.
Catalytic Converters target toxic vehicle emissions such as carbon monoxide and hydrocarbons.
Noble metal catalysts facilitate complete combustion of exhaust gases.
3
Match Wet Scrubber with its targeted pollutant type.
Wet Scrubbers target acidic gas emissions such as SO2SO_2.
Liquid absorbents spray and dissolve gaseous pollutants.
4
Match Incinerator with its primary waste treatment role.
Incinerators handle thermal destruction of hazardous solid and infectious wastes.
Controlled high-temperature burning decomposes organic hazardous materials.
