TRASAR® Technology
is the only program that provides real-time, on-line
monitoring capability. It can save water and energy,
and the improved system performance leads to better
efficiency, reliability and productivity.
TRASAR® is a versatile technology
that allows Nalco to determine where its products
are going during the treatment process and how effectively
they are working. It solves two typical problems with
today's industrial water treatment systems: overfeeding
and underfeeding. TRASAR® eliminates the application
of unnecessary chemicals, saving the customer money.
TRASAR® also prevents underfeeding, thus eliminating
poor performance and extending equipment run life.
Direct, real-time control by
TRASAR® measures the actual chemical level in the
system. Chemical injection systems linked to the
TRASAR® controller keep the treatment at the target
levels, continuously making automatic adjustments.
The results include: greater accuracy, tighter
control and better reliability than indirect control.
TRASAR®
Technology uses a patented fluorescent measurement
technique that works as follows:
- A specific ingredient (a "tracer") is blended into TRASAR® treatment products at precise concentrations
- The product is fed
and a sample measured by a fluorometer. Inside
the fluorometer, the sample flows through a
flow cell in an on-line controller or it is
contained in a sample cuvette in a benchtop
fluorometer
- The sample is exposed to a filtered
light source that causes optical excitation
of the fluorescent molecule and ultimately emits
a fluorescent light that is read by a detection
device. The quantity of emitted light is proportional
to the amount of treatment chemical
- In an automated system, the signal generated
is used to monitor and control chemical additions
on a "real-time" basis
