89-01: Reducing Copper Corrosion and Discharge Via a Novel Inhibitor andThe A. B. 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.

in wet-dry mode and zero visible plume in dry mode

During the past decade

0 ppm of poly DADMAC is effective for removal of turbidity up to 300 NTU and higher concentration

This specification offers recommendations for classification

the paper provides recommended design concepts for future reuse cooling towers where biological or hydrocarbon fouling risks are anticipated

Operational data will be presented explaining how these stresses were managed using a comprehensive treatment

more environmentally friendly yellow metal corrosion inhibitors

A major factor in the success or failure of any cooling water treatment program is the control and monitoring strategy used

we will review the advantage from being able to run at higher cycles of concentration

other plastics have the reputation of high flammability
