95-03: The Devil You Know Versus The Devil You Don't - An Evaluation ofWhen evaluating options for control of impending infestation of Zebra mussels, all too often decisions are made solely based on using chemistry historically added for general biological control. Is this the right treatment? This paper reviews the option of a non oxidizing biocide in direct comparison to chlorine in zebra mussel control applications.

The present paper shows the key points for French utilities

A detailed description of both the design and operation will be given

and conventional power (surface and salt water cooled)

In the past

The paper deals with cooling tower replacement

• Are environmental discharge limitations satisfied

cooling towers control the calcium concentration in circulating loops by adjusting the volume of liquid blow-down

wet bulb temperature

much of the procedure has application for wood towers as well

the chemistry of the cooling water does not support the growth of Legionella pneumophila

This document discusses some of the methods associated with practical control of corrosion in cooling systems

when poorly controlled
