3D TRASAR
5500 - Installation & Operation Manual
3. I'm already using TRASAR, why should I switch to 3D TRASAR Scale Control?
3D TRASAR Scale Control not only monitors product feed but also provides a superior level of
control by monitoring the active polymer level in the system and determining the scaling tendency of
the cooling tower. With 3D TRASAR Scale Control, scaling stress is automatically reduced by
maintaining the desired active polymer level in the system or by automatically blowing down the
system when needed.
• TRASAR provides only product feed set point control. It does not measure any scaling tendency
or system performance of the cooling tower.
• 3D TRASAR Scale Control employs a new improved Fluorometer with better accuracy for better
product feed control.
• 3D TRASAR Scale Control can maintain the desired residual tagged polymer level to minimize/
avoid scaling.
• 3D TRASAR Scale Control also allows one to determine if deviations from the learned normal
non-scaling operating condition is occurring in real time, so that corrective actions can be taken
automatically (blowdown or feed more scale inhibitor when needed) to minimize and/or prevent
scaling of critical heat exchanger surfaces.
4. What differences will I see when I run 3D TRASAR Scale Control compared to what
I do now?
• Polymer feed level will be constant while the TRASAR level may vary.
• Conductivity set point may automatically be adjusted in response to changes in scaling stress
(one-drum programs).
• Conductivity set point or tagged polymer product set point may automatically be adjusted in
response to changes in scaling stress (two-drum programs).
5. What are the unique benefits of 3D TRASAR Scale Control?
• Optimize water and chemical use by actively managing the system based on the stresses placed
upon it.
• Improve throughput by maintaining equipment at peak efficiency, even as operational factors vary.
• Reduce downtime and maintenance costs by preventing mineral scale and particulate fouling.
• Increase asset life and maintain asset reliability by preventing degradation during upsets and
process leaks.
6. Is 3D TRASAR Scale Control compatible with other components (Bio and
Corrosion inhibitors) of the cooling water treatment program?
Yes
. 3D TRASAR Scale Control can be run with 3D TRASAR Bio and Corrosion Inhibitor pro-
grams.
Note
: Nalco 90005 for algae may cause interference with 3D TRASAR Scale Control due to foam-
ing. The interference can be avoided/minimized by using antifoams.
