SYSTEM OPERATION
The Reef Pure RO Systems - 6 Stage Expert RO/DI System is a high-end RO/DI system designed to
produce up to 400 GPD (1514 Litres Per Day) or approximately 63 litres per hour of high quality, reef
grade, RO/DI water.
As this system includes a booster pump, excellent water pressure is assured, allowing the system to
perform e
ffi
ciently and effectively.
Most RO/DI systems are designed to work with a 4:1 wastewater to production water ratio. This means
that for every 1 litre of RO/DI water produced, 4 litres will be diverted to the wastewater line. This water is
not suitable for use in your reef aquarium as it contains all of the rejected salts that your RO membrane
has
fi
ltered out.
However, this system halves the wastewater ratio produced by regular RO/DI systems by adding a
second RO membrane, doubling the amount of RO/DI water produced from the same amount of
waste water.
Never use hot water (water warmer than 45
℃
). Using warm or hot water will cause
permanent damage to your RO membrane, requiring the membrane to be replaced.
Do not use the system in direct sun as it will deplete deionisation resin cartridges and
can quickly heat the system causing permanent damage to the RO membrane.
