TP16-22: ASHRAE Legionella Standard 188: Evidence-Based Interpretation and Application Sidestream Softening

TP16-22: ASHRAE Legionella Standard 188: Evidence-Based Interpretation and Application Sidestream SofteningThe first U. S. standard for the prevention of Legionnaires' disease was publishedby the American Society of Heating, Refrigerating and Air conditioning Engineers (ASHRAE) on June 26, 2015. The normative sections of the standard include development of a Water Management Plan for building water systems and devices including open and closed circuit cooling towers and evaporative condensers. ASHRAE Standard 188 is a process standard and critical

conductivity

We have developed a proven system that allows a cooling tower to remain in operation with the basin drained so the above maintenance can be completed

a 5MW gas turbine generator in a combined cycle with a 39MW steam turbine-generator at the Rio Pecos Station located on the Pecos River

A major component of the makeup is evaporation of water from the cooling tower

Also in this paper an investigation is made using measurements of the mass transfer rates and pressure drops for a comprehensive range of PVC plastic packing producing an economic comparison to find the best geometry and range

chlorine dioxide

The CTI drift measurement code ATC-140 specifies that isokinetic measurements be employed for cooling tower drift emissions measurements

Proposed and present methods are compared

The paper presents the results of field tests at five plants with ACC's to determine the mechanism and magnitude of the effects

The structural design considerations for dead

these waters can successfully be utilized for cooling water makeup

and similar models to correlate water chemistry to corrosion rates and inhibitor dosage
