Cloud chamber technology uses electrically charged water droplets to attract fine particles and remove them from exhaust streams. At the Saint-Gobain Advanced Ceramics Boron Nitride (formerly Carborundum) plant in Amherst, N.Y., the technology has exceeded required performance criteria and helped a plant with an air pollution control problem remain a part of the local industrial community.
