Legionellosis Guideline - GDL 159 TestingThe purpose of this guideline is to provide practices that reduce the risk of exposure to Legionella from evaporative head rejection systems, specifically evaporative condensers, closed circuit cooling towers, and open circuit cooling towers. December 2021
The modifications consisted of installation of Munters D-15 eliminators over the existing eliminators
with one tower equipped with means of cycling AC direct drive fan motors off and on
The culture method is a poor fit for routine assessment of operating risk of Legionella in cooling water systems because operators cannot make timely decisions about corrective actions
The new program has a wide application range for calcium (15 to 1000 ppm as CaCO3) and pH (7
cleaned up algal masses and reduced biofilms in the cooling systems
we will present some of our polyelectrolyte application experiences at various industrial locations
During the test batch Na-hypochlorite dosing was unable to mitigate the biofilm significantly
Low Pressure Axial flow fans
This new inhibitor performs well across a wide range of hardness conditions and pH values
Changes in cooling Tower design and water treatment practices are
such as the various restrictions due to water air pollution control and how we are trying to live with these
and limited water resources
