Principles of Wet Electrostatic Precipitator (WESP) Technology:
Electrostatic precipitation is made possible by the corona discharge. Through an effect known as the avalanche process, the corona discharge provides a simple and stable means of generating the ions to electrically charge and collect suspended air particles. Once charged, the particles are driven to the ground surface. The particles are then rinsed from the vertical collection surface with an irrigating liquid to the bottom sump where they are collected and discharged from the system.
In contrast to the up-flow system, the down-flow WESP system offers:
