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
And Health
The
role of water in dieting.
Drinking
water may be the most important piece to the weight loss puzzle. Water
contains no calories, fat, or cholesterol and is low in sodium. It is
nature's appetite suppressant, and it helps the body to metabolize fat.
Current research shows that low water intakes yield an increase in fat
deposits. Conversely, a high water intake reduces the amount fat deposits.
Without enough water, the kidneys cannot function properly.
As a result,
some of their workload is pushed off onto the liver, in turn preventing
the liver from operating at peak levels.
How does
all this tie into weight loss? Because metabolizing fat is a primary function
of the liver, and because the liver can't function at peak levels when
taking on the added workload from the kidneys, less body fat is metabolized
and more is stored. This leads to either weight gain or reaching a plateau
of weight loss.
When dieting,
we restrict the calories we take in, to some degree. By doing so, we lessen
the total amount of water available to our bodies since about 30% of the
average person's water intake comes from the food they eat. This gives
us even more reason to raise our water intake.
Can water
Help Me Lose Weight?
There's debate
as to how efficiently water exercise burns calories. Katz says there's
some evidence that water exercise isn't as effective as land exercise
for losing body fat. One reason is that the big muscles in the legs and
buttocks don't have to work as hard in water. Nevertheless, she says,
water exercise can contribute to weight management. Strenuous exercise
curbs appetite and promotes relaxation, factors in controlling compulsive
eating. Also, studies of water walking have showed that the number of
calories burned increases with the depth of the water.
Katz says
a half-hour of deep-water running burns 300 calories, compared with 200-250
for running on land, 150 for tennis, and 150-200 for aerobics. Also, a
150-pound person swimming at his or her target heart rate burns about
600 calories per hour.
