Which method is best for the separation of suspended particulate matter? Why?

Asked by Topperlearning User 4th June 2014, 1:23 PM
Answered by Expert

Suspended particulate matter can be best separated through electrostatic precipitators.

(1) In an electrostatic precipitator, gas or an air stream containing dust, smoke soot and other particulate matter is passed through a chamber containing electrically charged plates.

(2) The particles may get charged naturally when they pass through the charged plates.

(3) The electrically charged particles stick to the charged metal plates inside the precipitator.

(4) Knocking on the plates drops the particles into a hopper tray for disposal. Clean gas or air passes out of the precipitator.

(5) Upto 90% of particulate matter in thermal plants can be removed by electrostatic precipitators.
