Prior
to
the
installation
of
HydroFLOW,
the
conductivity
of
the
cooling
tower
was
maintained
at
roughly
1,500
µS
via
constant
blow
down
(opened
drain
valve).
The
goal
was
to
maintain
conductivity
between
1,500
to
1,800
µS
while
reducing
water
usage
by
up
to
50%
and
keeping
the
cooling
tower
free
of
scale
accumulation.
Note:
Since
the
automatic
blow
down
mechanism
was
not
opera;onal,
blow
down
was
reduced
by
slightly
closing
the
valve
every
1-2
weeks.
Other
readings:
Iron
-
Fluctuated
between
0.00
to
0.07.
Alkalinity
-
Started
at
240.
One
week
after
HydroFLOW was
installed
it
reduced
to
180
and
remained
at
that
value.
Nitrate
-
Fluctuated
between
560
to
640.
Results:
1.
Lime
scale
accumulaVon
stopped
as
soon
as HydroFLOW was
installed.
2.
Anti-scalant
and
Anti-corrosive
were
completely
discontinued
after
1.5
months.
3.
ExisVng
scale
and
biofilm
deposits
were
gradually
removed.
4.
After
reducing
the
biocide
by
75%,
the
total
bacteria
counts
conVnued
to
be
minimal.
5.
Blow
down
was
reduced
by
75%.
Note:
Blow
down
can
be
reduced
further
with
10%
side
stream
filtration.
6.
Efficiency
of
chillers
was
maintained
(no
scale
and
biofilm
accumulaVon
in
chiller
tubes).
7.
Under
one
year
Return
on
Investment
(ROI).
