of Legionella
Legionella
is a fairly common bacterium
found in water, which if inhaled
can cause pneumonia like
symptoms that can lead to severe
complications and even death.
The bacterium is transmitted to
humans in tiny water droplets
that are small enough to be
inhaled into the base of the
lungs. This is of importance
since cooling towers, by their
very nature, send a mist of
water into the air as part of
the evaporation process that is
used to cool the water. Listed
below are several suggestions to
help prevent a possible outbreak
of Legionaire’s disease.
- Insure
that the tower sump is free
of sediment.
- Make
sure that high efficiency
drift eliminators are in
place, and in good repair.
- Prevent
areas of stagnation.
- Use
proper microbiological
treatment. The suggested
treatment is to maintain
continual halogenation
(chlorine or bromine) with a
0.5 to 1.0 ppm free
residual. If halogenation is
intermittent then utilizing
a non-oxiding biocide is
also recommended.
Additionally, a
bio-dispersant will help to
penetrate any slime masses.
- Regularly
test the level of
microbiological activity and
add sufficient biocide (oxiding
or non-oxiding) to maintain
a total bacteria population
below 10,000 cfu/ml.
- Utilize
proper scale and corrosion
control products.
- Whenever
operations personnel are
working in or around cooling
towers a filter mask that
covers the nose and mouth is
suggested
