Question

Which one of the following is not a device used to control a particulate matter?

• A. Arresters
• B. Scrubbers
• C. Filters
• D. Electrostatic precipitator
• E. Incinerator

Answer 1

The correct option is E

Incinerator

Explanation for correct option

(E) Incinerator

Particulate matter

• Small, suspended solid particles or liquid droplets make up particulate matter.
• They are different chemically from one another and are air pollutants.
• A thermal procedure cannot be used to handle these matters.

Incinerator

• When organic waste products are burned, it is referred to as an incineration, which is a thermal operation.
• The incinerator produces gases, particles, and heat as its output.
• Therefore particulate pollutants must be filtered and precipitators must be constructed to remove the gases produced by combustion.
• These in no way control emissions of particulates by incinerator.
• Waste is converted into ash, flue gas, and heat during incineration.
• The majority of the waste's inorganic components are what make up the ash, which can appear as solid lumps or as tiny particles transported by the flue gas.

Explanation for incorrect options

• Arresters, Scrubbers, Filters and Electrostatic precipitator are the devices which used to control a particulate matter.
• Hence, all the other option (A), (B), (C) and (D) are incorrect.

Therefore the correct option is (E) Incinerator.
