ABSTRACT:
A method and apparatus are disclosed wherein an a.c. signal charges droplets sprayed into a chamber as the droplets are formed. The frequency of the a.c. signal is high enough so that the individual droplets are charged differently than their neighbors. The differently charged droplets create a nonuniform electric field within the chamber. The nonuniform electric field causes particles, entering the chamber in a fluid medium such as air, to be attracted to and attach to the droplets thereby precipitating out of the fluid medium.
