Cooling water, corrosion inhibitors monitoring

Industrial Cooling Water Systems Waters used for recirculating cooling systems can either be scaling or corrosive. Corrosive waters are treated with corrosion inhibitors which require monitoring for overall assessment of the treatment programme. 

However, azoles are commonly employed in cooling water formulations as yellow-metal corrosion inhibitors, and thus provide a potential source of interference. In addition, the technology monitors only the residual azole in the recirculating water and cannot directly provide an assurance of the integrity of the waterside metal, protective inhibitor film. Finally, TRASAR technology still requires periodic conventional wet tests for confirmation.
