New AirKnowledge Training Materials

EPA’s AirKnowledge program develops training material focused on the Clean Air Act. New materials are now available:

• A new self-instructional course describes the role, industrial use, components, operation, performance parameters, and design variables of cyclones, fabric filters, electrostatic precipitators, and wet scrubbers.
• An updated self-instructional module explains what greenhouse gases are, in the context of their effect on climate.
