Primary & Secondary pollutant. Definition: A primary pollutant is an air pollutant emitted directly from a source. A secondary pollutant is not directly emitted as such, but forms when other pollutants (primary pollutants) react in the atmosphere.
The primary cleaner is normally a wet scrubber,which removes about 90 percent of the remaining particulate. The secondary cleaner is a high-energywet scrubber (usually a venturi) or an electrostatic precipitator, either of which can remove up to 90percent of the particulate that eludes the primary cleaner.
