89-01: Reducing Copper Corrosion and Discharge Via a Novel Inhibitor and Cooling Tower Water Treatment Programs field-erected towers can only be

field-erected towers can only be tested on-site once built

workable preventative solutions

With the motor industry presently completing its transition to NEMA T frames

make-up water contains a low dissolved solids index and its main contaminants are aluminum and iron

Results show that the sensitive paper technique is still the most reliable method

Hopkins Generating Station operates under severe copper discharge limits of 30 ppb at the discharge point. A program of continuous feed of 3 ppm of Tolyltriazole reduced Admiralty Brass corrosion rates from 1. 5 mpy to 0. 15 mpy, and copper discharge from 400 ppb to 120 ppb. A new proprietary inhibitor, which is feed for 10 minutes every 3 weeks to 5 ppm active reduced corrosion rates to 0. 0w mpy and copper discharge to 20 25 ppb.
