Results from experimental cooling tower tests and field tests confirm that corrosion rates and pitting rates generally decrease as the Ryznar Index decreases. The effects of slug dosages of cyanide or sulfide were also investigated. Fouling was a problem when no scale inhibitor was used, when polyphosphates were added at pH values greater than 8, or when the mild steel corrosion rates were high.
