Abstract. Although the wet electrostatic precipitator or WESP, operates on the same basic principles as the dry type of unit, the major difference is that the charged particulates, on arriving at the collector, are removed by a flushing liquid rather than by mechanical rapping. Otherwise they both function in the same manner.
