Now you can have your own mini water treatment plant right under or next to your own sink! Your system will utilize a two to four stage treatment process, including reverse osmosis and sediment & carbon filtration, for very thorough contact time and full spectrum reduction of contaminants. Water is oxygenated and cleaned molecule by molecule, leaving you with the freshest, best tasting water available!

Whether you are interested in home or office systems, under the sink or countertop, the drinking water systems sold at U.S. Pure Water Corporation use a combination of the following stages of treatment (described in detail below) in various configurations. The combination of reverse osmosis (RO) and carbon filtration when configured precisely correctly and with high quality supporting parts, removes the broadest spectrum of contaminants possible, while maintaining a fresh "just squeezed taste". The process cleans and polishes your drinking water molecule by molecule, stripping it of harmful contaminants and unpleasant odors and tastes. It would be hard to find a purer, fresher water anywhere, in bottles, or in streams, rivers, or even in springs in France, than this water that you can have at your fingertips at your very own kitchen sink!

Sediment Filtration

Municipal Water at your tap is diverted from your cold water line into your system. It first passes through a 5 micron sediment filter which traps debris and turbidity down to a particle size of 5 microns (about the size of a grain of flour).

CARBON BLOCK Filtration

(This Stage May Occur After or Before and After the Reverse Osmosis Stage)

As water is forced through the micro pores of the carbon filter, organics in the water adhere, or "hang on" to (or molecularly bond with) the carbon. This is known as "adsorption". Activated carbon has earned a name for its effectiveness in reducing chlorine and low molecular weight organics (VOCs), such as THMs, TCE, pesticides and herbicides and other chemicals found in industrial waste. Carbon also virtually eliminates bad taste and odor. Because carbon reduces light weight gaseous volatile chemicals (which are some of the most toxic), and not heavier weight contaminants (minerals and metals) we call this partial spectrum treatment. Our carbon filter is manufactured using a method of extrusion that allows the free formation of the carbon in a highly uniform fashion. Because of the excellent porosity, permeability and uniformity of the media in these filters, contact with the media is assured, allowing a very thorough adsorption of chlorine, THM's, TCE, vinyl chloride, carbon tetrachloride, bad tastes and odors, pesticides, herbicides, VOCs (volatile organic chemicals), and more. As these molecules are some of the most toxic of the chemical contaminants found in tap water AND they are not removed by reverse osmosis (the molecules are too small to be removed by the straining action of the ultra filtration feature, and due to their light weight they are not repelled by the selective permeability feature of the membrane), it is important that carbon filtration be used in conjunction with reverse osmosis. The pore size of the carbon block filter is available in a range of 10 micron to sub-micron depending on your system and your needs.

REVERSE OSMOSIS FILTRATION

The water then undergoes the process of reverse osmosis (RO), which has 2 functions. First, it is the ultimate mechanical filter, straining out virtually all particulate matter, turbidity, bacteria, microorganisms, asbestos and heavier organics. It's pores are .0005 of a micron (or .0000002-two ten millionths of an inch-smaller than can be seen by the best optical microscopes (one bacteria may measure in at .02 to 1 micron, which is 40-2,000 x larger than the membrane pore size!)

REVERSE OSMOSIS SELECTIVE PERMEABILITY

The second function, is its removal of dissolved impurities (i.e. heavy metals & mineral salts)- even those smaller than the water molecules themselves. When water is forced across a semipermeable membrane, molecular forces allow only pure water molecules (H2O) and oxygen to diffuse through and collect on the other side of the membrane, while charged non water molecules are repelled from the surface of the membrane and diverted aside, leaving you with only the purest and freshest water available.

What RO Removes:

1. Particulate matter, turbidity, sediment
2. Colloidal Matter
3. Total Dissolved Solids
4. Toxic Metals
5. Radioactive elements
6. Microorganisms
7. Fluoride/fluorine
8. Asbestos
9. Pesticides and Herbicides
10. Heavier organic molecules (MW>300)

Granular Activated Carbon (GAC Filtration)

(Operative in Selected Systems-or Indicated in Special Circumstances)

Water will then goes on through a granular activated carbon block filter (GAC) which is a form of charcoal formulated in small granules. As water passes around each little particle of carbon, the organics in the water adhere to the particles of carbon. This is known as adsorption. One pound of granular activated carbon has a total surface area of about 125 acres. GAC reduces low molecular weight volatile organics such as THM's, TCE, vinyl chloride, carbon tetrachloride, etc., some of the most toxic of the chemical contaminants found in tap water, as well as chlorine, pesticides and herbicides. It's advantage is it's enormous surface area. It's disadvantage is that water can create paths through it and "channel". It is used in areas with high sediment content and Carbon Block Filters may clog.

FINAL POLISHING-LAST PASS CARBON BLOCK

To ensure maximum freshness, water traveling from the tank to the faucet goes through a 1 or 5 micron carbon block filters for a final polishing and adsorption of any possible bad tastes or odors or toxics remaining.

THE COMBINATION

When you combine carbon filtration with reverse osmosis, you get the benefit of full spectrum purification.
