91-14: Update on White Rust Corrosion and Control History of Cooling Towers

91-14: Update on White Rust Corrosion and Control History of Cooling TowersThe problem of "white rust" of galvanized steel cooling towers is defined. The available published literature is reviewed briefly. Laboratory work designed to determine the impact of several chemical and physical parameters are described. The nature of the protective layer which forms on galvanized steel surfaces in contact with different chemical environments is described. A generic procedure to minimize white rust in new galvanized cooling towers is

flexibility and finally price

minimum requirements for non-framework members

This paper will discuss the science behind the inherent burning characteristics of different polymers

actual results for the return water temperature will be compared

The new patent-pending chemistry has been evaluated for its performance in electrochemical tests

mitigation and where applicable

A comparison of field versus lab microbiological testing methods and results will be presented that indicate if proper Guidelines will be provided for field microbiological monitoring
