TP17-02: Can Rusted Surfaces be Effectively Passivated to Reduce Further Corrosion Codes and StandardsThe industry standard corrosion monitoring practice for cooling water systems involves inserting a clean, pre weighed, metal specimen into a coupon rack and exposing it to the flowing water for a period of time, generally 30 90 days. Following exposure, the coupon is removed from the system, carefully cleaned, and reweighed. The weight loss is then related to an overall loss of metal thickness, which is typically expressed in terms of mils per year
The paper also includes an introductory evaluation of a newly proposed thermal based method for non-accredited orientation measurements of drift for in-field measurements on real cooling towers
Isothiazolone biocides have been used effectively for decades to control microbial growth in a variety of industrial water treatment applications
