What is Reverse Osmosis ? |
|
|
Reverse Osmosis, also known as Ultra-Filtration by the industry, represents state-of-the-art in
water treatment technology. Reverse Osmosis (RO) was developed in the late 1950's under U.S. Government funding, as a
method of desalinating sea water. Today, reverse osmosis has earn its name as the most convenient and thorough method
to filter water. It is used by most water bottling plants, and by many industries that require ultra-refined water in
manufacturing. Now this advanced technology is available to homes and offices for drinking water filtration. |

How It Works ? |
|
|
In short, it is the process by which water molecules are forced through a 0.0001 micron
semi-permeable membrane by water pressure. Long sheets of the membrane are ingeniously sandwiched together and rolled
up around a hollow central tube in a spiral fashion. This rolled-up configuration is commonly referred to as a spiral
wound membrane or module. They are available in different sizes for processing different quantities of water. Typically,
a module for home water treatment is as small as 2" diameter and 10" long, while one for industrial use may be 4"
diameter and 40" long.
For the membrane to be usable it must be in some type of container (membrane housing) so pressure can be maintained on
its surface. It is this pressure that supplies the energy to force the water through the membrane, separating it from
unwanted substances. The most amazing aspect of RO is that the substances left behind are automatically diverted to a
waste drain so they don't build up in the system as with conventional filtering devices. This is accomplished by using
a part of the unprocessed water (feed water) to carry away the rejected substances to the drain, thus keeping the
membrane clean. This is the reason to why RO membranes can last so long and perform like new with minimum maintenance
even after years of operation. |

Water Quality : How is RO water compared to bottled water ? |
|
|
Just as good or even better. We use the same technology, reverse osmosis (RO), as other major
bottling plants use to filter water. Our drinking water has a sweet taste with a touch of minerals but not like the
flat taste of distilled or bottled water. The five-stage system is the most stable and complete RO process. The best
part is that you maintain your system and ensure your family's health yourself |

RO Filtration : How effective is Reverse Osmosis filtration compared to other methods ? |
|
|
RO is the most convenient and effective method of water filtration. It filters water by
squeezing water through a semi-permeable membrane, which is rated at 0.0001 micron (equals to 0.00000004 inch!). This
is the technology used to make bottled water, it is also the only technology capable of desalinating sea water, making
it into drinking water.
Non-RO water filters are much less effective, and the pore size on these filter media are much bigger, generally 0.5 -
10 micron. They can filter out coarse particles, sediments and elements only up to their micron rating. Anything finer
and most dissolved substances cannot be filtered out. As a result, water is far less clean and safe compare to reverse
osmosis filtration. |
