Many cooling tower designs now require special consideration to reduce their impact on the environment and facilitate site permitting. Unique designs will be discussed including: low noise applications; injectional scrubbed flue gas into natural draft cooling towers; drift requirements as low as .0001%; new EPA testing methods, environmentally critical thermal performance; removal, redesign and replacement of asbestos products with alternate materials; water conservation; zero discharge towers and elimination of plume through the use of a wet/dry cooling tower.
