17-12: Current Microbiological Control Techniques in Cooling Tower Water SystemDue to the recent out breaks of Legionnaires Disease such as in New York City it was decided to investigate how and why this could have occurred by cooling tower water systems that were chemically treated. Cooling tower water systems are normally treated by the traditional method of applying microbiocides and often monitored with traditional total bacteria monitoring methods. This has prompted a detailed review of the traditional microbiological

Improving these inflow conditions allows an increase in the overall airintake of the tower and thereby improves its cooling capability

A Total Quality Management (TQM) Program consists of at least three topics: Quality Function Development

These limits place an impact on the type of water treatment used in the majority of cooling-tower water systems

A new treatment technology designed for acid free high LSI cooling system operation is described

cost effective

which is consisted of all wet and wet/dry lanes

In addition to comparing their design similarities and differences

and addressing individual environments

Prediction of recirculation allowances is generally provided by CTI (Cooling Technology Institute

which comes with inherent hazards of pushing plant equipment to unscheduled downtime associated with extensive fouling and/or failure

air-cooled heat exchangers require too much capital cost
