90-12: Comparison of Two Isokinetic Drift Measurement Methods Legionella

90-12: Comparison of Two Isokinetic Drift Measurement Methods LegionellaA recent major cooling tower installation included a requirement for a very low drift rate guarantee and testing by the EPA stack gas sampling method 13A, modified on cooling tower application, and significant scatter in results have been reported. A study was commissioned with both Environmental Systems Corporation and Midwest Research Institute to conduct modified Method 13A, tests over a variety of eliminators. The tests were conducted under

The paper describes the behavior of supersaturated moist air in the space above the cooling tower where the formation of the

fan or stack size or type

Parish lake made the construction of cooling towers essential with the last two generating units

plant processes

sometimes referred to as Propeller fans

The basis for these concerns relate to measurable amounts of copper that can be detected in cooling waters in contact with copper in the incoming water

Some case histories are also discussed

Yellow metallurgy (copper and its alloy including admiralty brass) has been widely used in heat exchangers due to its high thermal conductivity

for use as fill and cladding in cooling towers

Non-Chemical Devices (NCDs) have great appeal when talking of the impact of treatment chemicals
