Question

Cyclone collectors and electrostatic precipitators are meant for controlling.

• A. Sewage pollution
• B. Air pollution
• C. Pesticide pollution
• D. Natural pollution

Answer 1

The correct option is B Air pollution

A cyclonic separation is a method of removing particulates from an air stream, without the use of filters, through vortex separation.

An electrostatic precipitator is a device that removes suspended dust particles from a gas or exhaust by applying a high-voltage electrostatic charge and collecting the particles on charged plates.

Both are instruments in controlling air pollution in industries.

So, the correct option 'Air pollution'.
