16-11: Using ATC-128 For Sound Testing & Verification In The FieldThis paper will evaluate the standard and published data for small towers per ATC 128 with respect to usability for acoustical consultants. Through testing of fully operationally field installed units and test stand towers some challenges and opportunities have been identified to help improve the use and accuracy of ATC 128. Using ATC 128 in the field has distinct challenges associated with height, distance, and background noise. The paper includes a

and heat transfer resistance

Make-up waters with elevated calcium hardness tend to increase the risk of scaling in circulating cooling systems where the concentration of calcium increases through higher Cycles of Concentration (COC)

concrete core sampling and laboratory testing are used to characterize materials quality and durability

The cleaning and diversion while maintaining tower operation and plant operation has never before been attempted anywhere in Canada and is possible the first ever done anywhere in the world

This paper is based on 6-7 years of field experience with zero blowdown systems

While the extent of deactivation varied with each biocide

Dolphin "pulsed power" water treatment was found to perform as well or better than chemical treatment when judged by the appearance of the chiller and tower fill

A recurring problem of industrial cooling systems is deposition of particulates brought into the cooling system from outside the unit and those particulates generated within the system

Drift eliminators are commonly incorporated in wet cooling towers to reduce the amount of water droplet losses

the results of which can be (1) reduced effectiveness of the chiller
