00-09: First Field trials of Single-Feed, Liquid Bromide Biocide for CoolingThis paper describes the results obtained in the first field trials of a new single feed, liquid bromine biocide. Several different water treatment service companies applied the product to a number of comfort cooling towers. The testing program embraced a variety of cooling tower designs and types of fill. Performance was measured in a diverse number of ways, and with varying degrees of sophistication, ranging from maintaining a pre set ORP in the

In June of 1982 a revised version of ATC-105 was published because several changes and additions were necessary to improve the code

the existing laws governing the discharge of molybdate are reviewed and the future disposition of this material scrutinized

developed by EVAPCO

there is a great need to specify a cooling tower to optimize the system

especially since we face a population explosion and an unheard of industrial expansion

the high price of carbon fiber at that time precluded industrial applications

Such legislation has resulted in the steady de-emphasis of chromate-based treatments in favor of more environmentally safe programs

(2) the existence of a legal duty by a chemical water treater to test for or "control" Legionella bacterium

This paper will present both field and laboratory test data independently obtained from operating cooling tower water systems that rely solely on PEFDs for microbiological control

This paper will utilize the main strategies of ‘green’

This paper documents thermal performance improvements in large industrial crossflow cooling towers through the innovative application of film fill
