Q01.
What is PURe-PURe Reverse Osmosis (R. O.) Water System? |
| |
PURe-PURe
R. O. Water System is a Home Drinking Water System that uses the principle
of Reverse Osmosis to remove 95-99.9% of all the mineral and chemical contaminants
from raw tap water. PURe-PURe R. O. Water System gives you the quality of
bottled water with the convenience of a faucet mounted on your kitchen sink. |

Q02.
How does Reverse Osmosis differ from a water filters? |
| |
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. |

Q03.
What is 'Membrane'? |
| |
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 to 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
PURe-PURe 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. |

Q04.
What is '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. |

Q05.
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. (More...) |

Q06.
What is the actual process of PURe-PURe R. O. Water 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. FILTER
4 The Reverse Osmosis membrane (TFC) which will separate 95-99.9% of the
dissolved contaminants from the water molecules. The contaminants are then
washed down the drain. The next stage of the PURe-PURe R. O. Water System
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
PURe-PURe R. O. Water 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). |

Q07.
What is 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. |

Q08.
What contaminants does Reverse Osmosis Remove ? |
|
The
PURe-PURe R. O. Water 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, a
partial list of other contaminants removed by the Re1812-70 TFC membrane
is shown here. The
percentage of removal shown is a conservative estimate. |

Q09.
Will Reverse Osmosis 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. |

|
Q10.
Can Reverse Osmosis 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. |

|
|
|
|
Q11.
How does PURe-PURe R. O. drinking water taste like? |
| |
The
taste of the PURe-PURe R. O. 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).
|
| |
|
| |
|
|
|
| |
Q12.
How will PURe-PURe R. O. 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, concentrated juices, and beer
as an alternative to bad-tasting tap water. Also, PURe-PURe 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. |

Q13.
Don't we need minerals from the water ? |
| |
Cells
in our bodies must be furnished with the mineral nourishment they need,
in order to accomplish their work. The minerals in natural water from springs,
wells, rivers, lakes and from the faucet, are incompatible with cell needs.
Water containing nothing but hydrogen and oxygen is pure water, and this
is the only kind of water, which the blood and the lymph can use in their
work. PURe-PURe R. O. collects and removes the inorganic minerals which
have been rejected by the cell of the body. The most constructive minerals
are those, which are contained in the raw vegetables, fruits, herbs, nuts
and seeds. These mineral are an integral part of the live organic water
of the juices of these natural raw products. |

Q14.
Where is PURe-PURe R. O. Water System going to be installed? |
| |
The
PURe-PURe R. O. Water 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. |

| |
Q16.
Can we connect PURe-PURe R. O. Water System 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 PURe-PURe R. O. Water System to all of their
bathrooms. |
| |
|
| |
|
|
|
| |
Q17.
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 T can be overcome TDS 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 PURe-PURe R. O. Water System include RE1812-70 The Thin Film Composite (TFC) membranes
combine the best of these characteristics and are considered the finest membrane in the world.
|
|
|
| |
|
|
|
|
Q18.
How much water can PURe-PURe R. O. Water System produce? |
|
Under
ideal conditions, the RE1812-70 TFC membrane is rated at 70 gallons of production
per day (70 gpd at 60 psi, 95 gpd at 100 psi). 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.
|
|
|
| |
|
|
|
|
Q19.
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 PURe-PURe R. O.
Water System.

Q20.
What guarantee is offered to PURe-PURe R. O. Water System? |
| |
PURe-PURe R. O. Water System (excluding filters) is guaranteed for 1 years for material and workmanship. The defective
parts will be replaced free within the first year. The membrane has a one year pro-rated guarantee. (more...)
|
| |
|
| |
|
|
|
| |
Q21.
What is the maintenance schedule for PURe-PURe R. O. Water 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 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 pre-filters. Just
order the needed filters from us and all systems come with the housing wrench
to open the filter housings, so you can maintain your system yourself and
feel confident about your drinking water. |
| |
|
| |
|
|
|
| |
Q22.
When do I need to change the membrane? |
| |
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 helps you to know when you should change
the R.O. membrane or the best buy unit (RO103TDS). |
