Clean Air Scrubbers |
||||||
 |
||||||
 |
||||||
| The coal burned to power this wood processing plant emits gas waste laden with polluting particles. Anti-pollution devices called scrubbers (visible as metal pipes) are used to trap the particles from the gaseous emissions. The scrubbers prevent most of these particles from entering the atmosphere, where they can change into environmentally damaging compounds such as acid rain. | ||||||
