Reverse Osmosis systems are recommended by the Centers for Disease Control and the EPA as one of the most effective ways of protecting residential drinking water!

 

WHAT IS REVERSE OSMOSIS?
 In order to reverse the natural tendencies of water and salt movement, and force clean water to flow from salty water, the osmonic pressure must be overcome, i.e. osmosis must be reversed. In order to reverse this flow of water, membrane systems, and Reverse Osmosis systems in particular, utilize a special constructed semi-permeable membrane element enclosed inside a pressure vessel. Pressure is applied to reverse the flow of water, the source of which is usually and existing, pressure is applied to the feed stream, water molecules are passed through the membrane, while salts are retained in the feed. Thus, utilizing the principles of water and salts movement, and combining them with pressure and membrane technology, the natural osmonic flow of solution is reversed.

HOW DOES REVERSE OSMOSIS WORK?
The RO process uses a semi-permeable TFC membrane to remove and reject up to 99% of impurities and contaminants from water. Contaminants such as iron, lead, nitrate, magnesium, copper, sodium, bacteria, viruses, and much more can be eliminated using only water pressure.

 WHY SHOULD SOMEONE CONSIDER PURCHASING A REVERSE OSMOSIS SYSTEM?
Reverse osmosis system should be purchased by anyone who is concerned about the quality, taste, odor or levels of dissolved minerals in their drinking water.

WHAT ARE THE SPECIFIC CONTAMINANTS THAT A REVERSE OSMOSIS SYSTEM REMOVES?
 A reverse osmosis system can treat for a variety of contaminants including:

Health Contaminants

Aesthetic Contaminants

Arsenic

(Taste, Odor, and Color Organic Molecules)
Asbestos Aluminum
Atrazine* Chlorides
Benzene* Chlorine*
Cryptosporidium Copper
Cyanide Silver
Fluoride Sodium
Giardia Sulfide
Lead  
Mercury  
Nitrates  
Radium  
Radon*  
Trichloroethylene*  
Total Trihalomethanes*  

*Additional treatment for these contaminants is provided through carbon filters included with our RO systems.

 

HOW DOES THE REVERSE OSMOSIS SYSTEM COMPARE TO JUST A FILTER?

The quality of the water is much better, your ice cubes will be clear and fresh, and the water will taste better. This is accomplished by using a combination of the three most effective water treatment technologies known. An expert from the office of Water Research and Technology said in the U.S. Dept. of the Interior Publication, 24-000-00855-0: "For general treatment (of water) to reduce both organic and inorganic loading to tolerable levels at lower energy costs, Reverse Osmosis (RO) offers significant advantages. It can accomplish the removal of many classes of contaminates to the desired degree of purity simultaneously. The significance of Reverse Osmosis (RO) is that it provides an additional processing tool with a broader capability, combined with lower energy costs, that has been available in the past.

 

WILL A REVERSE OSMOSIS WATER SYSTEM TASTE AS GOOD AS THE WATER I PAY $5.00 A BOTTLE FOR?

Yes! Sometimes better, depending how well the bottled water company is maintaining their purification equipment. Reverse Osmosis is the same process used by most major bottled water companies. Even some companies that use "spring water" still use Reverse Osmosis to insure purity.

 

I HAVE HEARD THAT REVERSE OSMOSIS AND WATER SOFTENING SYSTEM WASTE A LOT OF WATER!

Absolutely not! On the average, these systems will use less than 2% of your home's total water consumption. In addition, all Our Reverse Osmosis Systems use water conservation valves and our Water Softener Systems utilize a low water use piston.

 

HOW DOES MEMBRANE SEPARATE SUBSTANCES?
 Metals, Organic compounds, and other contaminants are either too large, or due to their chemistry unable, to pass through the reverse osmosis membrane.

HOW LONG DOES IT TAKE TO FILL A TANK?
It depends on; line pressure, storage capacity, membrane capacity, and temperature.
For a 3-Gallon Tank (at 50 psi, 25°C):

Membrane Capacity

Fill Time

25 Gallons Per Day Membrane Capacity

3.0 hours

35 Gallons Per Day Membrane Capacity

2.0 hours

50 Gallons Per Day Membrane Capacity

1.4hours

75 Gallons Per Day Membrane Capacity

.9 hours

Note: Individual performance of each membrane can be higher or lower, depending on the actual pressure used.
Size Comparison:

Comparatively, if a water molecule were the size of a tennis ball. Protozoa would be the size of Mount St. Helens.
Most metals and inorganic compounds would be the size of a softball. Bacteria would be the size of a pyramid.
Most organic compounds would be the size of a basketball. Viruses would be the size of a bus.

Typical Reverse Osmosis Contaminant Rejection
Contaminant Rejection Contaminant Rejection Contaminant Rejection
Sodium 85%-93% Iron 85%-93% Potassium 85%-93%
Aluminum 96%-99% Magnesium 96%-98% Fluoride 87%-93%
Lead 96%-99% Zinc 98%-99% Nickel 98%-99%
Copper 98%-99% Chloride 87%-93% Silver 93%-98%
Arsenic 94%-96% Nitrate 60%-92% Bicarbonate 90%-95%
Mercury 96%-98% Silicate 85%-90% Manganese 95%-98%
Sulfate 96%-98% Cyanide 86%-92% Ammonium 86%-92%
Calcium 96%-98% Sulphite 98%-99% Barium 96%-98%
Phosphate 96%-99% Bacteria 99% + Chromium 96%-98%

Actual results may vary depending on source water.
