92-07: Biocidal Aspects of Ozone for Cooling Water Treatment - Probable Impacts DriveshaftsSome ozone suppliers claim Biocidal benefits of ozone throughout the cooling systems. Yet the short half life of ozone coupled with the high ozone demands of cooling waters make it unreasonable to expect that any residual ozone will be present shortly after its application. Most cooling intake waters contain bromide ion (from traces up to 1. 5 mg L). Oxidization of bromide ion with ozone is known to produce the hypobromous acid hypobromite ion (HOBr

and water leakage

Choosing the correct biocide program for your particular system requires assessing factors other than free chlorine levels and planktonic microbe counts

and how it can be controlled before and after the tower is assembled

It has also shown excellent compatibility with other commonly used corrosion inhibitive chemistries

Common causes of system failure unrelated to water treatment include: (a) Operational Issues

These subjects are addressed with case history documentation

fouling deposition

The latter is often desirable for both cost of treatment and the effectiveness

elevating the exposure

Improved products often have to overcome a certain resistance

After a series of tests and trial cathodic protection systems

suggest ways these hazards/risks could be mitigated
