Rejection rate test
You can test the efficiency (mineral rejection rate) of the RO
membrane as follows:
•
Turn off the Feed Water Valve.
•
Turn off the Tank valve.
•
Release system pressure by opening the faucet valve over
the sink.
•
Turn on the Feed Water Valve.
•
Slide the switch to the FEED position and hold the faucet
open until the reading stabilizes. This is the feed water TDS.
•
Slide the switch to the RO position and hold the faucet open
until the reading stabilizes. This is the RO water TDS.
•
Compute the mineral rejection rate = 1 – (RO water TDS /
feed water TDS).
•
Recording the mineral rejection rate over time shows the
“health” of the RO membrane. This directly affects the
amount of 000 TDS water produced by a set of DI filters.

The Mineral Mizer is now ready for use. To check the
mineral content, slide the Water Quality Monitor’s
switch to the
FEED
position. Turn the monitor on by
pressing its ON/OFF switch. The display shows the
water’s mineral content, expressed in ppm TDS. This
number will normally be in the 000 - 002 range. If the
number is higher than 004, allow the tank to fill until
the display is consistently in the 000 – 002 range and
then discard the water as before. This should take no
more than a few minutes. It will take about 3 hours to
fill the Tank, depending on local water pressure and
temperature.
