20-04: Using an Ultrasound Measurement Technology to Monitor Real-Time Biofilm OzoneMicrobial (MB) growth management in cooling systems requires an integrated approach to control both suspended (planktonic) and sessile bacteria (biofilm) through proper chemical treatment and monitoring. Technologies are now moving toward in situ monitoring of microbial growth in the cooling system. This paper reviews an advanced technology to monitor and, ultimately, to optimize the chemical usage for MB control. The core of the integrated MB control

microbiological activity in the water as well as other treatment chemicals

by key technical and economic factors

and in cold climates freeze-thaw deterioration

high efficient PVC drift eliminators and optimized distribution system

This paper discusses the current state of the art in applying ozone as a solo treatment and with supplementary cooling tower treatments

6-bis (ethylamino) -s-triazine) simultaneously

Silica removal is maintained at less than 100 ppm

This is a follow on to the Cost of Noise paper presented in 2008 (TP08-16)

Investigation into the cause of the catastrophic collapse and resulting methodology for evaluating the structural integrity of similar towers on the AEP System will be reviewed

This filter type also accumulates particles of high specific gravity within its housing causing the eventual costly replacement of its media
