Treatments and Programs for Cooling Water

This development was further accelerated when, in the late 1970s and early 1980s, chromates began to fall out of favor (for both environmental and occupational health reasons), and thus the need arose to find suitable (organic) alternatives for use as effective corrosion inhibitors. Various stabilized phosphate and zinc/organic programs were developed at this time 

These changes are primarily in response to the need for improved economic benefit and competitive advantage. Modem organic formulations may be used, for example, to meet the demands of the customer for new cooling water programs that can perform under greater operational efficiency, or, as a result of improved customer education, initiated by both the service companies and their suppliers of specialty, organic, and formulatory chemicals. 

It should also be noted that now, in the late 1990s, the most recent chemical introductions to the marketplace tend to be even more specialized and effective inhibitors (but are correspondingly more expensive) and 

This chapter will look at some of the most useful early cooling water treatments and later discuss many of the common inhibitor materials used plus various more modem programs, including their formulations and application.
