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. Higher Performance RO membranes Begin With Shorter Leaves
Flow Rate of Reverse Osmosis Systems All reverse osmosis systems are rated (and priced) by their flow rates (Gallons of Product Water Produces Per Day). The effectiveness and productivity of RO systems increase with greater water pressure and temperature. The actual flow rate (in GPD) of any reverse osmosis system depends on your home water pressure and temperature. This is why all of our systems are named as they are, for example: 36/45 GPD means it is rated at 36 GPD at 50 psi of water pressure, 45 GPD at 60 psi. While the industry standard* is set at 60 psi, we know that not everyone's cold water is at 60 psi and 77 degrees F. Instead of misleading customers into thinking that a 45 GPD system will guarantee a flow rate of 45 GPD, we remind you that you might get less than 45 GPD —perhaps 36 GPD or even less if your pressure and temperature are very low! So when flow rate is critical for you, you need to consider all these factors. *Please
note that the industry standard is not necessarily followed by all vendors. We
have seen other RO systems claiming 100 GPD at 100 psi —very unrealistic
input water pressure! So do check on these facts before you make a buying decision.

The
heart of a reverse osmosis system is, of course, its membrane. Yet not all membranes
are made the same. Different manufacturers fabricate their membranes differently.
For example, spiral-wound membranes are comprised of membrane "leaves" —individual
sheets of membrane through which feed water passes and is filtered. Some membrane
brands have fewer and larger leaves. Some have more and shorter leaves. Short-leaf
design costs more to fabricate, but is advantageous because less pressure is required
to deliver water to the end of each leaf, and more uniform flux is maintained
from one end of the leaf to the other. The result is a highly efficient membrane
—one that provides safer drinking water and a longer
life. For example, APEC's high quality water is achieved by advanced
