Oasis DP RO operation explained
Reverse osmosis is by far the most advanced water purification technology in use today. A special
semipermeable membrane structure similar in its properties to the membrane of a living cell is
capable of purifying drinking water from virtually all harmful impurities. The membrane can be thought
of as having tiny pores, 200 times smaller than viruses and 4000 times smaller than bacteria.
Reverse osmosis membranes harness the principle of body’s metabolism on a cellular level.
Only molecules of certain size can penetrate cellular membrane.
The Oasis DP is a five-stage filtration unit. Using the feed water adapter and feed valve the
water supply is connected to the pre-filtration housing head. Incoming water passes through pre-
filter cartridges (5 micron polyspun, Granulated activated carbon, 5 micron carbon block) designed
to remove solids (such as rust, sand, silt, etc), residual chlorine and organochlorines from water.
After undergoing pre-treatment in the pre-filters, water enters into the fourth (and most important)
stage: the reverse osmosis membrane installed in a special housing.
The inlet of membrane housing is connected through the feed side of auto shut-off valve. One of
the two outlets supplies purified water (permeate), and the other carries away water with rejected
impurities (concentrate). The membrane purifies water at the molecular level by passing
through its pores only the water molecules and the molecules of dissolved oxygen.

size, pure water

Inside the membrane, water is separated into two streams: concentrate, which is discharged
into drain, and permeate, which enters pressure tank for storage.
The tank is connected to the output through the membrane auto shut-off valve and check valve
built into the transition fitting that is installed in the permeate outlet of membrane housing. After
the auto shut-off valve is installed the union tee, through which the tank is connected to the filter
The pressure tank accumulates purified water. Without it, the reverse osmosis membrane wouldn’t be
able to produce sufficient flow for direct water consumption. Thus, the tank stores a supply of
purified water and delivers it to the user as needed, and then the unit generates a supply of water.
Time required to fill empty tank can range from 1.5 to 3 hours. After the tank has been filled the
auto shut-off valve shuts off the water supply from the pre-filters and the unit stops.
Whenever purified water is drawn off, the pressure of water in the tank lowers, and the auto shut-
off valve automatically resumes the flow of water through the pre-filter cartridges to the membrane to
re-fill pressure tank. Water with retained impurities (concentrate) is dis-charged into drain through
the concentrate outlet which is installed on a drain pipe. In order to create the backpressure
which is required to maintain the operating pressure inside the membrane housing, a orifice
type flow restricter is installed.
Finally, water is drawn through a carbon block post filter and a remineralising cartridge which improve
the taste and add calcium and magnesium making the water suitable for drinking.

Key Points
Because the processing speed of RO is very slow (around 130 to 750ml a minute) the unit is
supplied with 1a 2L pressure vessle to store the processed water for when it’s needed.
When in use, stored processed water is drawn from tank. The tank is recharges between use.
•A 12L tank holds 4L, so if unit used a frequently, production may seem low.
•Max processing capacity up to 190L a day.
•For every 1L of processed water, there is approximately 500ml of concentrate.

2.5 Production installation
➥Before installation, make sure the plumbing system has been installed as for the exhisting rules of the state of the art.
Install a bypass that permits unit's by-passing.
Install a check valve from the unit to the water mains.
For mains pressure over 8 bar (116 psi) a pressure reducer must be installed upstream from the product. Protect the
product against "water hammer" using an appropriate anti-water hammer system (expansion vessels, shock absorbers).
For mains pressure under 3 bar, install pump models (PUMP, PUMP-UV).
Presence and efficiency of the grounding of the power line.
Power line compatibility with the electrical specifications of booster pump (for PUMP models) and UV lamp (for UV models).
Power wires diameter over 1 mm.
Mains voltage stability (voltage peaks under 10%).

* If supply water pressure is below required value, purchase pumped model or fit your existing
filter with booster pump. If the pressure in the water system is above the limit, it is necessary to
install a pressure regulator on the main pipe.
** If pressure in tank bladder is outside this range, it is necessary to pump up or release the
pressure until it conforms to the requirement.
*** If supply water temperature is up in the range of +20…+30 °C (+68...+86 °F), rejection of
impurities will be decreased and system capacity increased, bringing about an increase in TDS.
Using the product with supply water temperature in excess of
+30 °C (+86 °F) is not recommended.
SUPPLY WATER QUALITY REQUIREMENTS*
Do not use with water that is microbiologically unsafe or of unknown quality without adequate
disinfecon before or aer the system.
* If water supply does not meet the requirements, service life of membrane and/or pre-lter cartridges may be shortened.
** If your home is supplied with raw wellwater, perform laboratory test of your water before installing a reverse osmo-
sis filter. If any of your water indices exceed the limit, consider using a water treatment system to correct supply water
quality. Refer to water treatment specialists or companies for advice and proper equipment selection.
