SPECIFICATIONS – 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 (414kPa) and 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, 25°±3°C, and 717 mg/l 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.
Non-potable Water Sources: Do not attempt to use this product to make safe drinking water from non-potable water sources. Do not use the system on
microbiologically unsafe water, or water of unknown quality without adequate disinfection before or after the system. This system is certified for cyst reduction and may be used on
disinfected water that may contain filterable cysts.
Arsenic Reduction: This system shall only be used for arsenic reduction on chlorinated water supplies containing detectable residual free chlorine at the system inlet. Water systems
using an inline chlorinator should provide a one minute chlorine contact time before the reverse osmosis system.
Nitrate/Nitrite Test Kit: This system is acceptable for treatment of influent concentrations of no more than 27mg/L nitrate and 3mg/L nitrite in combination measured as N. It is certified
for nitrate/nitrite reduction only for water supplies with a pressure of 280 kPa (40 psig) or greater. This system is supplied with a nitrate/nitrite test kit. Product water should be monitored
periodically according to the instructions provided with the test kit.
Product Water Testing: The Reverse Osmosis System contains a replaceable membrane cartridge critical for the effective reduction of total dissolved solids (TDS). Re-
placement of the reverse osmosis membrane cartridge: The reverse osmosis system contains a replaceable membrane cartridge critical to the efficiency of the system. This
membrane should be replaced every 18 months, or more often based on your local water. Only replace the reverse osmosis membrane with a part approved for use in your
Reverse Osmosis system.
