Qualified
System
Performance
Because
the performance of
a Reverse Osmosis
Membrane
is
highly dependent
upon pressure,
temperature
and
TDS,
the following should be used for comparison purposes only.
1
Industry standards
measure RO
Membranes performance with
no
back pressure
on
the
product
water, at 60
psig (4i4l<Pa) and
77°F
(25°C). Further conditions
on
the above
are 250
ppm
TDS
and
a
30.6%
recovery
rate.
Production
rate
and
TDS
reduction figures
are
for
a new
Membrane that has been rinsed for
24
hours. The production
rate
of
a new
Membrane
can
decrease by
10%
per year
or more,
depending
upon the
scaling and fouling tendencies of the
Feed
Water.
2
Measured
at
50
psi, 77°+2°F, and 717 mg/I
TDS
per
NSF/ANSI
Standard
58.
3
Efficiency rating
means
the
percentage
of the influent
water to
the
system that is
available
to
the
user as reverse osmosis
treated
water.
Under operating conditions that
approximate
typical daily usage.
4
Recovery rating
means
the
percentage
of the influent
water to
the membrane portion of
the system that is available
to
the user as reverse osmosis treated
water
when the
system
is
operated
without
a storage
tank
or
when the storage tank is
bypassed.
/j\
Do
not use
with
water
that is microbiologically unsafe
or
of unknown
water
quality
without adequate disinfection before
or
after the
system. Systems
certified for
cyst
reduction
may
be used
on
disinfected
waters
that
may contain filterable cysts.
/5\
Filter is only
to
be used with cold
water.
Systems certified for cyst reduction may be
used
on
disinfected
water
that
may contain filterable cysts.
