11-10: AWT’s ASHRAE Liaison Report: NCDs and Biological Control in CoolingAWTs (ASHRAE) Liaison Report presents and summarizes the recent ASHRAE research project, 1361 RP, on biological control in cooling water systems using non chemical treatment devices. The report presents the result of ASHRAEs controlled, independent, and scientific evaluation of several classes on non chemical treatment devices (NCDs) for efficacy in reducing planktonic (bulk water) and sessile (Biofilm) microbial populations within a pilot scale

Within the PVC family it will discuss regrinds

the process of removing and replacing packing (fill) in a cooling tower involves working at height in most cases

metal surfaces

produces a real hazard

selection of critical parameters and performance standards

which attract molybdate anions and bind them loosely by what may be regarded as week hydrogen bonds

on-demand generation of MIOX (mixed oxidant disinfecting solution) provides several advantages for the cooling tower industry

Pitting corrosion rates obtained by potentiodynamic polarization techniques will be presented in addition to general corrosion rates obtained by linear polarization techniques

These alternate tube designs were analyzed under a variety of flow conditions in controlled settings

This paper will focus on research efforts

their components must be tested individually in test cells designed to that effect

and what role jurisdictions such as OSHPD play
