Cloud Chamber Scrubber (CCS) technology, offered by Tri-Mer^® Corp., is sometimes confused with electrostatic precipitation (ESP) because both use electric charge. Aside from this similarity, the technologies are strikingly different. CCS uses charged droplets. Wet ESPs work by charging the particles in a gas stream, causing them to migrate through an electrostatic gradient to collectors, usually tubes or plates, where they are washed by a continuous film of water into a sump.

In contrast, CCS technology charges only the collector (that is, the water droplets) and moves the collectors to the particles. When a particle passes within 20 microns, the droplet charge induces a dipole force on the particle, which causes the particle to move the short distance to the droplet for capture and collection. The charged droplet “cloud” is able to handle even heavy particle loading with high efficiency.
