Question

Which one of the following will not control particulate pollutants?

• A. Incinerator
• B. Arrester
• C. Scrubber
• D. Filter
• E. Electrostatic precipitator

Answer 1

The correct option is A Incinerator

Incineration is also called as a thermal process, it involves combustion of organic substances contained in waste material. It converts the waste material into ash, gases, particles and heat which are then put into the application for generation of electricity. The incinerator is the device where waste is burnt e.g. furnace. Now incinerators are equipped with systems to reduce the emission of highly toxic gases during the process. The output of incinerator is gases, particles and heat thus for controlling particulate pollutant filtration and precipitators are installed to clean out the gases as a result of incineration. These do not have any control over particulate pollutants.

Hence the correct answer is 'Incinerator'.
