19-12: Control of Ozone Based on Water Temperature for Reduction of LegionellaIn the US, there is an estimated population of 500,000 to 600,000 cooling towers (US Department of Energy by the Pacific Northwest Laboratory, 1995) that provide cooling for both HVAC systems and industrial applications. Based on this number, we can extrapolate that the number of cooling towers worldwide is roughly 1. 5 million even though there are no figures to confirm this. Water being an excellent means to transfer and dispose of heat. During this

on all three types of catastrophes

The project was completed safely

To demonstrate this new corrosion inhibitors performance benefits

The second phase

The use of CO2 is a proven antiscalant treatment for cooling water systems and is applied in several plants in Europe

Pitting due to crevices

both laboratory and field performance data will be presented

many areas critically need more water for uses ranging from irrigation to domestic consumption

This guideline sets forth recommended design criteria

which recently won a "Green Chemistry" award

Energy conservation considerations have led to the increasing use of two speed motors and variable frequency drives for mechanical draft cooling towers
