99-07: Tweaking-The Art and Science of Successful Cooling Water TreatmentApplied cooling water chemical treatments are often accepted as the end of all and the cure for all system problems. In fact, environmentally accepted and safe to management cooling water treatments tend to not perform up to expectations without continuing tweaking. Furthermore, that which is tweaked must fit the cooling water chemistry, the system's needs and often the system's discharge needs. This manuscript specifically provides insight as to how

This paper discusses the PTC-11 Code and compares its requirements with measurement techniques currently being used in the moist environment of a wet cooling tower fan

This paper reports performance data and describes mechanisms for the following functions: 1) the control of microbial populations to very low levels

Current methodologies for using azoles to control yellow metal corrosion have existed for years with little advancement

Correlations between biofilm formation and measured water quality parameters were determined

other corrosion inhibitors have always been important

et cetera for cooling purposes

either fossil or nuclear fueled

as attempts are made to determine responsibility and to seek compensation for these failures

But to take full advantage of this life expectancy the designer must be aware of certain design parameters unique to composites that must be addressed

concrete surface treatments

and operators of mechanical and natural draft cooling towers with information related to corrosion of these critical structures

a series of thermal capacity tests were performed in both the controlled environs of a thermal laboratory and at an operating industrial refrigeration facility
