Reverse osmosis is the finest water filtration method known. This process will
allow the removal of particles as small as ions from a solution. It is used
to purify water and remove salts and other impurities in order to improve the
color, taste or properties of the fluid. R.O. uses a membrane that is semi-permeable,
allowing the fluid that is being purified to pass through it, while rejecting
other ions and contaminants from passing.
This technology uses a process
known as crossflow to allow the r.o. membrane to continually clean itself. This
is the reason of why an r.o. element can last many years before clogging or
need replacement. This
water purification process requires a driving force to push the fluid through
the membrane, and the most common force is household water pressure or pressure
from a booster pump. The higher the pressure, the larger the driving force and
efficiency.

Water can prevent and alleviate many of our symptoms
How
water regulates your inner cooling system.
Just like
your house, your body has an internal thermostat that it uses to regulate
your internal heating and cooling. This system is mostly influenced by
two systems, the integumentary and the circulatory system. The Human Body
is over 70% water and the skin (a water-tight collection of "dead" cells
at its surface) helps keep this percentage within acceptable ranges. This
narrow percentage range of acceptable values between fluid and tissue
is necessary to maintain a proper acidic environment for various chemical
reactions that sustain life.
The Integumentary
System consists of skin, hair and nails. Hair and nails have little to
with Emergency Medical Services (in spite of the fact that some females
"believe" that a 'bad hair day' or 'broken nail' constitutes justification
for calling an ambulance.) The skin is the largest organ in the human
body and that fact, coupled with its anatomical and physiological complexity,
practically warrants its treatment as a separate organ system.
The skin
serves three purposes. 1. Environmental protection 2. Temperature regulation,
and 3. Sensory input. The skin also provides environmental protection from
infection. This protection is breeched only when the skin is broken, highlighting
the necessity for antiseptic procedure when dealing with such circumstances.
Temperature control has a direct effect on metabolic rate, and metabolic
rate a direct effect of the "quality" of existence. The body's metabolic
process is an exothermic one, creating a significant amount of heat, and
in some external environments we are subjected to higher than optimal
temperatures.
Through a
process of evaporation, which produces a cooling effect, as an end result
of sweat production by the sweat glands in the skin, the human body can
control over-heating (whether from internal or external sources,) by routing
the blood into areas close to the surface of the skin, cooling the blood
and carrying that 'cooling effect' back to the interior of the body. On
the superior surface of the skull, where the skin is relatively thin and
immediately "backed-up" by the skull, the concentration of blood vessels
is relatively high, and consequently, major heat loss is experienced through
that region. It is also for this reason (the concentration of blood vessels)
that scalp wounds seem to bleed so profusely. When over heated (again,
from either internal or external sources) the patient will exhibit a flushed
or red appearance.
Please note
that it is not just the production of sweat that cools the patient. The
evaporation of that fluid is a necessary occurrence in the process. Consequently,
a sweating patient in a humid environment, where sweat is just collecting
on the skin, may still be overheated. In some external environments, patients
are exposed to colder than optimal temperatures, and the skin "helps"
maintain proper body temperature by first sensing the temperature variant
(the same as it might if the environment were too hot,) then shunting
the blood away from the exterior surface, thereby maintaining (or conserving)
body temperature. Patients experiencing hypothermia (to whatever degree)
will have a pale, or cyanotic appearance.
Of interest
at this point, is that the skin must "sense" the temperature variant,
then communicate that information to the brain, in order for the expected
outcome to be exhibited. The presentations as described above are "normal"
even though, under certain circumstances, they may be beyond acceptable
limits. If the environment, patient history and physical exam, and/or
other findings are dictating this "normal" presentation, but you "see"
something else, then the "communication" ability (Nervous System) or the
"sensory" ability (Integumentary System,) or sweat production ability,
may be compromised.
The human
circulatory system is called a Closed System because all of the blood
is contained within blood vessels and does not directly bathe body tissues.
Insects and other arthropods, as well as many other invertebrate animals
have Open Circulatory Systems wherein the blood flows from one or two
major vessels into body sinuses to directly bathe tissues. Oxygen is transported
indirectly through the body systems of arthropods through major sinus
cavities. The oxygen is bound sometimes to hemoglobin and sometimes to
other transport proteins such as hemocyanin (contains copper instead of
iron).
The blood
plasma plays a critical role in buffering the body's pH (blood pH values
usually are very close to 7.3), circulating antibodies from the immune
system, regulating osmotic balance, and even regulating body temperature.
It is the movement of water within your cellular system that transports
vital blood plasma. Blood plasma makes up 46-63 percent of the total blood
volume. Water accounts for 92 percent of the volume of plasma. Without
this delicate balance of water and plasma, your body would simply begin
to 'overheat'.
