81-15: A Breakdown in Cooling Tower Water Technology Dianodic II Legionnaires' Disease

81-15: A Breakdown in Cooling Tower Water Technology Dianodic II Legionnaires' DiseaseLaboratory and field data show the ability of this treatment to with stand system upsets such as acid spills and loss of dispersant feed.

the frequency of fan air flow testing to verify new or existing fan performances in cooling towers and air-cooled heat exchangers has increased

CFD was used to show that the large fan design virtually eliminates hot air recirculation compared to 5% to 35% recirculation rates of traditional small fan designs

atmospheric emissions from cooling towers can also be important considerations

the use of wastewater as a source of cooling tower makeup water can result in significant corrosion

a new factor has entered the engineer's consideration of cooling water treatment selection

The relative importance of recirculation and degradation of fan performance is discussed

The information within this standard is for the design

representatives was making an inspection of a chemical plant when a fire was discovered

cooling energy savings can range from 50% to 75%

due to its good corrosion resistance and heat transfer characteristics

the form of electrically charged particles (metallic ions)

There has been a shift in industrial economic philosophy to risk-based maintenance
