After completion of this course, learners will be able to describe the role, industrial use, components, operation, performance parameters, and design variables of fabric filters, electrostatic precipitators, cyclones, and wet scrubbers. While this course does not cover all stationary source control technologies for particulate matter, it does cover control technologies that are key to controlling particulate matter emissions. The wet scrubber module will be updated soon to improve the learning experience.
