electrostatic precipitation

electrostatic precipitation
a process that removes suspended dust particles from a gas by applying a high voltage electrostatic charge to the particles and collecting them on charged plates
Hypernyms: ↑industrial process

* * *

: removal of suspended particles (as dust and acid mists) from a gas (as air or blast-furnace gas) by charging the particles and precipitating them by applying a strong electric field (as by passing the gas between collecting and discharge electrodes in a precipitator) — compare cottrell process
