86-19: A Chrome/Zinc-Based Cooling Water Treatment for Systems Operating Natural Draft Towers

86-19: A Chrome/Zinc-Based Cooling Water Treatment for Systems Operating Natural Draft TowersWhere the use of hexavalent chrome is permissible, chrome zinc based cooling water programs are perhaps the most cost effective means of treatment. Chromate and zinc, however, offer only limited protection against the pitting type corrosion associated with iron deposition on cooling system surfaces. Under reducing conditions the effectiveness of chrome zinc based programs for corrosion control is severely limited. Reducing conditions generally require
