Application Guidelines

(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

o

F (25

o

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..

Functional Description

Feed  water  enters  the  5-micron  pre-filter  (combination  5  micron/carbon  filter  in  2  sump  models),  which
filters out suspended particles such as dirt or sediment. The filtered water then enters the pre-carbon filter
(3  sump  models  only),  which  contains  granular  activated  carbon,  which  removes  any  chlorine  from  the
water. The two sump models utilize a combination 5-micron/carbon filter to filter fine particles and remove
chlorine. 

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 2/3 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.
