74-12: Evolution of Non-Polluting MicrobicidesThe criterion of efficiency in every single phase of industry today is without question. Any operation that does not function at optimum represents a loss of energy that cannot be tolerated. Included as a basic part of industry is process cooling by means of cooling tower systems. In order for industrial processes to be carried on efficiently, these cooling systems must also operate efficiently, and this is a difficult and challenging assignment, in

Vibrations levels in the region of the natural frequency are empirically determined for composite drive shafts and multiple test methods for determining the natural frequency are described and compared

With the greater restrictions on drift emissions that are now required in many locales

Some of these features are not obvious to the casual observer and if not chosen correctly can adversely affect tower performance

workmanship and methods of testing glass-fiber reinforced plastic panels in various profiles intended for use as casing

The plant chemical processes are cooled by 3 mechanical draft-cooling towers with a combined recirculation rate of 267

Because of the direct impact that a cooling tower has on the system in which it is to be used

This was a unique test

and polymer dosage-and their effects on the dispersion of colloidal silt and iron oxide particles-are discussed

Chromate-based inhibitors have been widely used in cooling systems for corrosion control for many years

The Paper will address an innovative technique for assessing the condition of reinforced concrete elements in Mechanical Draft Cooling Towers while on-line and off-line
