Question

An electrostatic precipitator is an electric device to remove suspended impurities from water

• A. True
• B. False

Answer 1

The correct option is B False

The above statement is false.

Explanation

1. An electrostatic precipitator (ESP) removes particles from a gas stream by charging them positively or negatively with electrical energy. This directs that it works on a gas stream rather than a water medium.
2. It works either on solid or liquid particles.
3. The charged particles are then drawn to collector plates that are charged in the opposite direction.
4. The collected particles can either be removed as dry material (dry ESPs) or washed away from the collector plates using water (wet ESPs).
5. Collection efficiencies of more than 99 percent are possible using ESPs.
