95-14: Iron Rot - The "New" NemesisIron rot has been with us all along, however, it has increase in significance since the changes in water treatment procedures brought about by the EPA's banning of the use of chromate. It is a reason for major repair work, and is starting to rival internal fungus attack as a causative factor. Where to look for, and how to recognize iron rot is reviewed. This paper covers the mechanisms of this type of attack, and ways to avoid or minimize iron rot.

This document serves as a guideline for techniques and instrumentation that can be used to measure airflow and other fan performance parameters on induced draft in situ heat rejection equipment having axial fans

The cleaning involved structural modifications of nine (9) of the eleven (11) cells and a diversion of 100

are used to project a life expectancy of the tower at a given level of probability

It will also cover flame spread ratings

This guideline offers recommendations for the use of Portland cement concrete in the use of mechanical draft cooling towers

When operated to duplicate conventional cooling tower output for a given application

A third phase

Our studies demonstrate a need to revisit current biocide dosing practices in order to meet the new guidelines for Legionella control in industrial water systems

This paper discusses how the plant designed and implemented a trial to determine the costs and effects of improved microbial inhibition practices

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

We discuss training

They may be integrated with clarification and other treatment methods to achieve the desired cooling tower makeup quality
