Michael E. DeBakey VA Medical Center, Houston, TX USA, Chiller and Cooling Tower Water Treatment - Case Study
There are three main challenges for treating cooling water: Scale, Corrosion and BioGrowth.
WATER SYSTEM CHALLENGES
The traditional chemical treatment calls for chemicals to deal with these challengers. When scale is present, the condenser’s ability to transfer heat is reduced, causing higher pressure and higher temperatures hence more energy. Micobial growth induced corrosion which weakens components, reduces heat transfer efficiency and causes leakes, as well as reduces life expectancy of the equipment. There is another aspect of course, which is the hazards associated with the chemicals stored in the building.
The ScaleBuster technology enables the operator ro reduce chemicals while maintaining the system free of scale buildup, corrosion as well as Biological growth for maximum efficency while saving energy and reducing downtime.
In 2006, An EnviroTower system based on ScaleBuster® conditioning technology has been installed to treat the cooling system’s water.
In a short few months it was clear that the cooling system is in a better condition than before, most scale formation on the condenser (and other parts of the cooling system) were dissolved. The system had been scale-free since then! Operation costs (mainly energy, but also water, maintenance and of course chemicals) were cut drastically. System’s performance parameters were at their highest ever.
