Application Guidelines
Functional Description
Feed water enters the 5-micron pre-filter, which filters out suspended particles such as dirt or sediment. The filtered water
then enters the pre-carbon filter, which contains granular activated carbon, which removes any chlorine from the water.
The water then enters the reverse osmosis membrane. The membrane will allow only permeate (product water) to pass
through. The brine (waste water) goes to the drain.
Permeate then flows through a hydraulic shut-off valve to the storage tank. When the tank fills and the tank pressure
reaches approximately 40% to 65% of the inlet feed water pressure, the shut-off valve closes, which turns the system off.
When water is drawn from the faucet, permeate flows from the storage tank through the post carbon filter. This filter
contains granulated activated carbon, removing any taste and odor that has accumulated while stored in the tank. When
the tank empties, the shut-off valve opens, turning the unit on.
Please refer to the Flow Diagram on page 19 .
(1) Nominal product water ratings are based on the following conditions: Supply TDS of 250 ppm
softened tap water, 50 psi (0.36 Mpa), 77°F (25°C), pH 8 and 15% recovery with outlet to
atmosphere.
(2) Rejection percentages are dependent on the supply conditions and the substance being measured.
Notes: The performance of a reverse osmosis membrane is highly dependent upon pressure,
temperature and TDS. The actual volume of product water and rejection percentage will vary with
differences from the test conditions that membrane ratings are based upon.
These drinking water systems are not intended to be used for the treatment of water that is
microbiologically unsafe or of unknown quality.
