75-02: Environmental Considerations in Cooling Tower TreatmentSince the beginning of this decade, a new factor has entered the engineer's consideration of cooling water treatment selection. This factor, our environment, has made many of us make significant change in our thinking and the method of treatment in cooling towers. The days of feeding any corrosion inhibitor, biocide or other treating agent without considering its effect on the environment is gone forever. What has caused this change, what have we been

water consumption and GHG emissions each of which will be delineated

water treatment

and operational reliability for evaporative cooling equipment

A comparison of air cooled verses water cooled systems will be approached from several vantage points

and life-cycle costs

A large semi-closed cooling water system was created ten years ago and since has had aggressive corrosion attack particularly on carbon steel surfaces

The understanding of structure-biodegradability correlations has led to the development of new

we will discuss the value of non-oxidizing biocides and industry best practices to control biofouling in cooling systems

extensive environmental sampling programs are maintained

and indicate that significant economic advantages can be realized

The main computer program options are then discussed
