86-04: Experience With Galvanized Cooling on Alkaline Treatment Programs Cooling Tower ConversionThe trend toward high pH cooling water treatment programs and their effect on hot dip galvanized cooling towers is discussed. Included are typical ranges of cooling water quality, corrosion rates experienced in the systems and deposit composition when experienced. The effects of concentration cells on galvanized steel in high solids water will be addressed. Also included are observations and experiences for maintaining trouble free operation.

Biofilms or microbiological growth on surfaces can negatively impact the operation of cooling systems in many ways by impeding efficient heat transfer in heat exchangers

communicate lessons learned from field installations and give the reader a practical guide to the installation and use of this type of motor

The modifications consisted of installation of Munters D-15 eliminators over the existing eliminators

has necessitated the use of cooling towers over the traditional once-through systems

is irreversible and often results in premature and costly wood replacement

The cooling water treatment program is designed to control CaCO3 scaling at Langelier Saturation Index values approaching +3

injectional scrubbed flue gas into natural draft cooling towers

OEM's and suppliers are facing lower and lower near and far field noise limits with respect to their equipment

including the makeup to cooling towers

Case histories are provided from Dow Chemical that outlines results of Kimre units in operation for 1½ -2 years

While factory-assembled cooling towers are compact enough to be tested and certified in environmental test chambers
