Reverse Osmosis is the process of which normal City Water gets
filtered to make it very save, and healthy for drinking. Below
is a detailed graph of each step of the whole process.
RO - Step 1 -
Activated Carbon Filter removes Chlorine and Odors.
RO - Step 2 -
Micron Filter removes dirt, rust, and other particles.
RO - Step 3 -
Reverse Osmosis removes salts, lead, and impurities.
RO - Step 4 -
Post Carbon Filter which improves the taste of the water.
RO - Step 5 -
Ultraviolet Light which is the process repeated to ensure
safe, high quality drinking water.
The Result is Fresh, Great Tasting Water using
Reverse Osmosis.

What is Reverse Osmosis
Reverse
Osmosis, also known as hyper filtration, is the finest filtration known. This
process will allow the removal of particles as small as ions from a solution.
Reverse Osmosis is used to purify water and remove salts and other impurities in
order to improve the color, taste or properties of the fluid. It can be used to
purify fluids such as ethanol and glycol, which will pass through the Reverse
Osmosis membrane, while rejecting other ions and contaminants from passing. The
most common use for Reverse Osmosis is in purifying water. It is used to produce
water that meets the most demanding specifications that are currently in place.
Reverse
Osmosis is capable of rejecting bacteria, salts, sugars, proteins, particles,
dyes, and other constituents that have a molecular weight of greater than
150-250 Daltons. The separation of ions with reverse osmosis is aided by charged
particles. This means that dissolved ions that carry a charge, such as salts,
are more likely to be rejected by the membrane than those that are not charged,
such as organics. The larger the charge and the larger the particle, the more
likely it will be rejected. Reverse Osmosis uses a membrane that is semi
permeable, allowing fluid that is being purified to pass through it, while
rejecting the contaminants that remain.
Most
Reverse Osmosis Technology uses a process known as cross flow to allow the
membrane to continually clean itself. As some of the fluid passes through a
membrane the rest continues downstream, sweeping the rejected species away from
the membrane. The process of Reverse Osmosis requires a driving force to push
the fluid through the membrane, and the most common force is pressure from a
pump. The higher the pressure, the larger the driving force. As the
concentration of the fluid being rejected increases, the driving force required
to continue concentrating the fluid increases.
Only very
small molecules are able to pass through the pores of an RO membrane. Even
dissolved mineral molecules are too large to penetrate the pores. For example,
pesticides, bacteria, and viruses are unable to pass through the pores of the
membrane, and therefore are flushed down the drain.
RO
filtration can remove up to 99% of most contaminants including arsenic,
nitrates, radium, chromium, fluoride, and dissolved solids such as sodium,
calcium, iron, magnesium, copper, etc. Please see the following link for a full

RO systems
come with filters that can process about 4,000-5,000 gallons of pure water.
Average usage of approximately 10 gallons of pure water per day would allow
these filters to last more than one year. However, even if you use less than the
standard 10 gallons per day, we recommend filter replacement each year to
maximize the effectiveness of your Reverse Osmosis Water Filtration System.
