Following is a detailed description of each of the steps in our purification process. While this material
is fairly technical, this piece is intended for a general audience. Those readers with additional questions
about DrinkMore Water's technology may directly contact the engineer who designed the system
(who also happens to be our founder!), Bob Perini, at (301) 417-9333.

1. Sediment Filter

Our complex purification process begins with a simple, pleated-paper sediment filter. This filter traps relatively
large particles which may be present in the water-things like dirt, sand, slime and grit. It's necessary to start the
process with this basic step in order to remove these large particles which could foul or clog the more sensitive
equipment used at later stages.

(A classic before and after picture -hard to believe that’s only Step 1! )

Our initial sediment filter is rated at 10 microns (a micron is one-millionth of a meter, or 1/25,000th of an inch.)
How small is that? Well, the human eye can only see particles 20 microns in diameter or larger. You'd be very
surprised at what we see when we change these filters.

2. Ion Exchange

The next step is the removal of various metallic elements through a process known as ion exchange. Sometimes
referred to as water "softening," ion exchange utilizes large tanks which are filled with a special, negatively-charged
resin. The resin serves as a reservoir for large numbers of positively charged sodium and potassium ions.

As water passes through the ion exchange system, metallic ions, which carry a strong positive charge, displace
the more weakly charged sodium and potassium ions. The metallic ions are thus trapped via electromagnetic
attraction to the resin particles. The ion exchange beds are then automatically cleansed and regenerated at prescribed
intervals based on water volume.

Ion exchange provides highly effective removal of the metals responsible for pipe scaling and deposits.
The process also removes various heavy metals, such as lead, mercury, iron, and cadmium, which have been
associated with well-publicized health concerns.

From DrinkMore Water's perspective, it is important to remove metals early in the purification process to protect
the more sensitive technology used in later steps, since high levels of metals can damage this equipment.

3. Activated Carbon

Once the water passes through the ion exchange sys-tem, it moves into an oversized granular activated carbon bed.
Carbon filtration (also known as charcoal filtration), which utilizes a process known as adsorption, is a particularly
effective technique for chlorine removal. Pesticides, herbicides, and other organic contaminants
(especially volatile organics) are also removed at this stage.

Carbon also does an excellent job of removing trihalomethanes (THMs) from the water. THMs are a class of chemicals
which result from the interaction of chlorine and decaying organic matter in the public water supply. These chemicals
are known carcinogens, and the high levels found in local water supplies have been a cause for concern in recent years.
Granular activated carbon filtration is the most common technology used in home filter systems. Unfortunately,
these home systems are often poorly maintained. In some cases, filters are not cleaned properly, or filter elements
are not changed at appropriate intervals. Over time, effectiveness declines, and in some cases the contaminants in
an over-loaded filter actually begin to discharge back into the water.

Furthermore, there have been numerous instances of bacterial contamination associated with poorly maintained home
filter systems. At DrinkMore Water, our carbon filters are "backwashed" on an automatic cycle every 24 hours.
Maintenance and filter replacements are carried out by trained engineers in accordance with a predetermined schedule.

4. Five Micron Carbon Block Filter

The five micron carbon block filter is designed to capture extremely small particles present in the water. The five micron
size designation indicates that particles larger than five millionths of a meter will be captured by the filter. The filter itself
is composed of an extruded block of carbon, providing an additional measure of adsorptive capacity for the removal of
chlorine and organic contaminants. The extruded carbon block filter is manufactured to very tight tolerances, thereby
providing optimal permeability and porosity characteristics for adsorbing and removing contaminants.

5. One Micron Carbon Block Filter

The one micron carbon block filter immediately follows its five micron counterpart. At this stage, particles as small
as one millionth of a meter are trapped and removed from the water.

Filters of this extraordinarily small pore size are capable of eliminating even the cryptosporidium cyst, an organism
responsible for numerous waterborne illness outbreaks. As you may recall, cryptosporidium was the organism that
Washington, DC feared was contaminating the water supply during the 1993 "boil water alert."

Cryptosporidium in the water supply comes encased in an oocyst, or egg, an egg which doesn't hatch until it
finds a suitable host, such as the human gastrointestinal tract. It's important to note that one of the biggest
concerns with organisms of this type is that they cannot be eradicated via conventional chlorination and sand
filtration techniques commonly employed by municipal water systems. However, these oocysts are between
4 and 6 microns in diameter, so they can't pass through the one micron carbon block filter (nor can they pass through
step 6, 7, 8, 9 or 10 of the DrinkMore Water process.)

Once the water has passed through the one micron filter, virtually all of the suspended particles have been trapped
and removed. However, dissolved substances can still remain in the water. Dissolved solids cannot be removed
via conventional filtration. A purification technology, such as the reverse osmosis technology employed by
DrinkMore Water later in this process, must be used to eliminate these types of dissolved impurities.

6. Ultraviolet Disinfection

Since the DrinkMore Water process removes all chlorine from the water, two forms of chemical-free disinfection
technology are employed to ensure that the purified water remains absolutely and completely free from any sort
of microbiological contamination. Ultraviolet disinfection is the first of these technologies.

At this step of the process, the water passes through a special chamber which houses a large ultraviolet
light source. This ultraviolet light acts as a powerful sterilizing agent. If any bacteria, viruses, or other
microbiological contaminants are present in the water, the ultraviolet light at this particular wavelength
destroys the genetic material within these organisms, eliminating the possibility of bacterial or
viral reproduction and proliferation. The organisms quickly die and are captured and removed
during the reverse osmosis purification process.

7. Dual-Pass Reverse Osmosis

Reverse osmosis is the centerpiece of the DrinkMore Water purification process. Many people
have heard about the process of osmosis. Osmosis is a naturally occurring process whereby
water passes across a membrane due to a pressure differential between one side of the
membrane and the other.

As osmosis takes place, the concentration of dissolved material on each side of the membrane moves
closer to an equilibrium state. That is, the more concentrated solution will tend to become more diluted,
and the more diluted solution will tend to become more concentrated. Many people are familiar with
osmosis as the process by which living cells receive nutrients and excrete wastes.

In reverse osmosis, high pressure is used to force water across a membrane while impurities are left
behind. In other words, the high pressure causes the impurities to become more concentrated on one
side of the membrane. Only the pure water is able to cross the membrane; even the dissolved impurities
which cannot be removed by conventional filtration are captured and eliminated by DrinkMore Water's
reverse osmosis purification system.

The reverse osmosis system featured at DrinkMore Water utilizes state-of-the-art technology for both
purified water production and quality control. Every drop of our purified water must pass through
approximately twenty layers of reverse osmosis membranes. The water which passes through the
first stage of reverse osmosis is then purified through a second set of reverse osmosis membranes.

If even a slight variation in quality occurs, an alarm is triggered and the entire system shuts down.
The result is a purity level that's second to none. In fact, we encourage you to compare our water
with any other water-spring water, mineral water, or filtered water.

8. Ozonation

The second phase of chemical-free disinfection is known as ozonation. Ozonation relies on oxygen
to ensure that our purified water remains free of any possible microbiological contamination.

The ozonation process takes basic molecular oxygen (O2) and passes it through a special chamber
in which it is exposed to a high voltage electrical charge. (This type of ozone generation is called
cold-plasma discharge.) The electricity causes the oxygen molecule to split and recombine in a
higher-energy form known as ozone (O3). This ozone is then continuously circulated through the purified water.

Ozone is a very powerful disinfectant and is capable of oxidizing a very broad range of contaminants.
In fact, ozone is highly effective against many types of impurities and organisms, such as cryptosporidium,
that are utterly impervious to chlorination. Just how powerful is ozone? First of all, it's about 1,500
times more effective than chlorine as an oxidant.

In real life, ozone is very effective at killing cryptosporidium. Tests have shown that at normal
concentration levels (1 part per million), ozone will destroy 99.99% of cryptosporidium oocysts given
five minutes of contact time. Chlorine, however, doesn't affect cryptosporidium oocyst viability at
concentrations of 30,000 parts per million for a period of eighteen hours. The standard concentration
of chlorine in tap water is around 3 parts per million-imagine what 30,000 parts per million would taste like!

Ozone is not a stable state for oxygen, and over the course of a few minutes it returns to its
natural O2 state. This state-of-the-art disinfection system is simple, yet extremely powerful.
And best of all, it relies on nothing more than all-natural oxygen-absolutely no strange chemicals or additives.

9. Storage & Recirculation

After the water has passed through the preceding eight steps it moves into the storage and
recirculation phase. This storage and recirculation system has been designed so that DrinkMore Water
will retain its exceptionally high purity and will not come into contact with any materials or substances
which could in any way compromise the quality of the water. DrinkMore Water features a storage system
made entirely of stainless steel. Many people are unaware that brass, a key component of many plumbing
systems, can be a primary source of lead contamination. By using only stainless steel, this problem, and the
problem of potential interactions with other substances, is completely avoided.

DrinkMore Water does not simply sit in storage after purification. Instead, the water continuously
travels through a recirculation loop. During recirculation, additional ozone is periodically added to
maintain the completely sterile and bacteria-free condition of the system.

10. Bottling /Purified Water Dispensing

When a bottle is filled at DrinkMore Water, the water is drawn directly from the continuous
recirculation loop and fed to our bottler. Like the water storage system, our water dispensers
utilize stainless steel on all water contact surfaces. You might want to check out the pictures of our new,
state-of-the-art bottling line. It's very cool!!
