Performance Data Sheet
Model: RO-PURE
General Use Conditions
1. System to be used with municipal or well water sources treated
and tested on regular basis to insure bacteriological safe quality.
Systems certified for cyst reduction may be used on disinfected
water that may contain filterable cysts.
WARNING
!
DO NOT use with water that is micro biologically unsafe or
unknown quality without adequate disinfection before and
after the system.
2. This system is acceptable for treatment of influent concentrations
of no more than 65 mg/L nitrate and 5 mg/L nitrite in combina-
tion measured as N and is certified for nitrate/nitrite reduction only
for water supplies with a pressure of 350 kPa (50 psig) or greater
along with an internal built in booster pump.
3. Operating Temperature: Maximum: 100°F (40.5°C)
Minimum: 40° (4.4°)
4. Operating Water Pressure: Maximum: 85 psi (6.0kg/cm2)
Minimum: 40 psi (2.8kg/cm2)
5. pH
Maximum: 11
Minimum: 2
6. Maximum Iron present in incoming water supply must be less
than 0.2 ppm.
7. Hardness of more than 10 grains per gallon (170 ppm) may
reduce RO membrane life expectancy.
8. Recommend TDS (Total Dissolved Solids) not to exceed
1800 ppm.

Note:
Depending on incoming feed water conditions, replacement
time may vary.
While testing was performed under standard laboratory condi-
tions, actual performance may vary depending on water chemistry,
water temperature, and water pressure. 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. Recovery rating means the per-
centage 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. There is an average of 4 gallons of reject water for
every 1 gallon of product water produced.
