Frequently Asked Question
Q: What is PurePro Home Reverse Osmosis System ?
PurePro RO Systems is a Home Drinking Water System
that uses the principle of reverse osmosis to remove
95-99% of all the mineral and chemical contaminants from
raw tap water. PurePro products gives you the quality of
bottled water with the convenience of a faucet mounted
on your kitchen sink.
Q: How does Reverse Osmosis differ from a Water
Filter ?
Ordinary water filters use a screen to separate only
particles of dirt sediment from water. Reverse osmosis
employs a semipermeable membrane that removes not only
particles but also an extremely high percentage of
dissolved contaminants-molecule by molecule- from raw
tap water.
Q: What is the membrane and how does it work ?
The membrane consists of several thin layers or
sheets of film that are bonded together and rolled in a
spiral configuration around a plastic tub (This is also
known as a thin film composite or TFC membrane.) The
material of the membrane is semipermeable : it allows
water molecules pass through while acting as a barrier
to dissolved solids (i.e.: mineral chemical
contaminants). When the feed water stream passes across
the surface of the membrane, the PurePro molecules
penetrate the membrane surface, working their way around
the spiral and collecting in the center tube. The
remaining contaminants are concentrated and washed from
the surface of the membrane down the drain.
Q: Can you explain Osmosis ?
Assume a membrane is semipermeable, allowing water to
pass through while being closed to dissolved salts.
Place a membrane between two compartments in a container
as shown in the figure to the right. Then place a salt
solution in one half of the container and pure water in
the other half. Now a fundamental scientific principle
comes into play. That is, two different concentrations
of liquids within the same system will try to reach
equilibrium (i.e. the same concentration of
contaminants) on both sides of the membrane. Of course
the only way for this to happen is for pure water to
pass through the membrane to the salt water side in an
attempt to reach equilibrium is called OSMOSIS.
Q: What is Reverse Osmosis ?
Reverse Osmosis is the reversal of the natural flow
of osmosis. In a water purification system, the goal is
not to dilute the salt solution, but to separate the
pure water from the salt and other contaminants. When
the natural osmotic flow is reversed, water from the
salt solution is forced through the membrane in the
opposite direction by application of pressure-thus the
term REVERSE OSMOSIS. Through this process, we are able
to produce pure water by screening out the salts and
other contaminants.
Q: What is the actual process of the PurePro Home R.O.
System ?
The raw tap water first flows through a 5 micron
particle FILTER[1] to remove dirt, rust and other
sediment. The water then flows into a carbon briquette
cartridge FILTER[2] which takes out 98% of the chlorine
and organic chemicals. The next stage of the process is
FILTER[3] 1 micron sediment filter or the Block carbon
filter to filter multi-chemical compounds and
suspension. [4] The reverse osmosis membrane (TFC) which
will separate 95-99% of the dissolved contaminants from
the water molecules. The contaminants are then washed
down the drain. The next stage of the PUREPRO RO SYSTEMS
process is the small CARBON FILTER [5] removes the
remaining traces of chemicals, tastes and odors. Typical
Flow Chart
The R.O. water is stored in a 3.2 gallons TANK[6].
Inside the tank is a balloon-like rubber diaphragm,
pre-charged with 8-10 psi of air. As the tank fills, the
air pressure increases and pushes the water out when the
faucet is opened. The final element of the PurePro
Series system is a POLISHED CHROME FAUCET [7]. It is
installed on the kitchen counter or the sink. It is a
dual action faucet offering intermittent flow (to fill a
glass, hold the handle down) or continuous flow (to fill
a coffee pot, lift the handle up).
Q: How did Reverse Osmosis get its start ?
Although the idea of reversing osmosis has been
known for over 10 years, the practical application is a
recent development. In 1962 the U.S Government funded
the first R.O. plant which processed 1000 gallons clean
water per day. Today, there are more than 3000 large R.O.
treatment plants, each producing more than a million
gallons of drinking water each day. In 1991, the U.S.
Army bought 8,000 large membranes to their mobile water
purification units for troops in Desert Storm. In 1993,
the U.S. Government bought another 6,300 large membranes
to purify flood water in the Midwest.
Q: Will R.O. remove Sodium from the water ?
YES! Reverse Osmosis was originally designed to make
sea water drinkable for the navy. It is ideal for anyone
on a low sodium diet.
Q: Does R.O. remove Bacteria ? Cryptosporidium ?
YES! An R.O. membrane has a pore size much smaller
than bacteria virus, pyrogen or the cryptosporidium
parasite. When functioning properly it will remove all
microorganisms from tap water and produce sterile water
.
Q: What does the PurePro series drinking water tast
like ?
The taste of the PurePro water depends on the amount
of contaminants in the tap water originally. If 95% of
dissolved minerals and chemicals are removed, the R.O.
water may taste like distilled water (no minerals),
bottled water (low mineral), or natural spring water
(moderate mineral content).
Q: How will the PurePro series water affect mixed
beverages ?
Because reverse osmosis removes invisible
contaminants that mask flavor, it allows the natural
taste of your beverages to come through. You will be
able to use less coffee and still get the full flavor.
Concentrated beverages like orange juice will taste
tangier. You will probably be drinking a lot more water
as well, since many people drink soda, Kool-Aid,
concentrated juices, and beer as an alternative to
bad-tasting tap water. Also, PurePro eliminates most of
the lime build up on drip coffee makers, preventing the
need for frequent cleaning. No longer will you find the
white scum on the inside of pans after boiling water.
Q: Don't people need minerals removed from the water
?
Most of the minerals that we receive are from the
foods we eat. Only a very small percentage comes from
the water we drink.
Q: Where is the PurePro series drinking water system
installed ?
The PurePro System is usually installed underneath
the kitchen sink. So installers prefer to locate the
equipment in the basement or in a crawl space since the
water may stay cooler there, and can be easily run up to
the kitchen sink, as well as to a refrigerator &
additional faucets in the home.
Q: Can the PurePro system be connected to an extra
faucet ?
It only takes a 1/4" tee and tubing to run the water
to a refrigerator or a extra faucet. Some families run
PurePro system to all of their bathrooms.
Q: What factors affect the quantity and the quality
of the water produced ?
There are four major variables to consider:
1. PRESSURE. The greater the water pressure, the better
the quantity and quality of the water produced. Water
pressure of 60 psi ideal. PurePro include one booster
pump can make sure the water pressure.
2.TEMPERATURE. 76*F is the ideal water temperature for
R.O. 40*F water will cause the production of R.O. water
to fall to half of that at 76*F. The maximum water
temperature recommended is 85*F.
3.TOTAL DISSOLVED SOLIDS (TDS). The higher the amount of
dissolved contaminants in the water, the lower the
quantity of water produced. A high level of TOTAL
DISSOLVED SOLIDS can be overcome with additional water
pressure.
4. MEMBRANE. Different membranes have different
characteristics. Some produce more water than others;
some have better contaminant rejection capabilities;
some have greater resistance to chemical abrasion for
longer life. PurePro system comes with TW30-1812-80 The
Thin Film Composite(TFC) membranes combine the best of
these characteristics and are considered the finest
membrane in the world.
Q: How much water does the PurePro system produce ?
Under ideal conditions, the TW30-1812-80 TFC
membrane is rated at 80gallons of production per day
(80gpd at 80~100psi). Under the average conditions, the
consumer can expect 70-95 gallons of product water per
day. But that's still a lot of water for the average
household's drinking and cooking requirements.
Q: Can the amount of water produced be increased ?
Yes. There are several ways: 1.At night, fill a
pitcher with water from the tank. The emptier the tank
the faster the water production. By morning the tank
will be filled with fresh water. 2. A second membrane
can be added. An additional membrane is required to
double the capacity of the PurePro System.
Q: What is the guarantee on the PurePro System ?
The PurePro System (excluding filters) is guaranteed
for 1 years for material and workmanship. All defective
parts will be replaced free within the first year. The
membrane has a one year pro-rated guarantee.
Q: What is the maintenance schedule for the PurePro
System ?
The three pre-filter cartridges should be changed
every 6 months. The first is a 5 micron sediment
cartridge. The second is a Carbon Cartridge. The third
is a 1 micron sediment filters. (some system comes with
the Extruded carbon filter.) Failure to change the
cartridge every 6 months may allow chlorine to destroy
the membrane. It is very easy to change the prefilters.
Just order the needed filters from us and all system
come with the housing wrench to open the filter housings
so you can maintain your system yourself and feel
confident about your drinking water.
Q:When should the membrane be changed ?
One indication is a gradual reduction in water
production caused by a layering of minerals and salts on
the membrane surface. Another is a gradual deterioration
in the quality of water being produced. You my notice a
different taste or more white scum on the inside of a
pan of water you are boiling. This might mean the R.O.
membrane is disintegrating and requires replacement.
(Note: Water Quality Tester TDSX1 help you to know when
you should change the R.O. membrane or the best buy unit
(RO103TDS).
Q: What contaminants does Reverse Osmosis Remove ?
The PurePro System contains a quality carbon filter
which will remove more than 98% of organic chemicals
from the water. These include THMs(chloroform), DBCP,
lindane, TCEs(trichloroethylene),
PCEs(tetrachloroethylene), carbon tetrachloride
chlorine, In addition to these organic chemicals, below
is a partial list of other contaminants removed by the
Re1812-70 TFC membrane. The percentage of removal shown
below is a conservative estimate.
