Did
you know?
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.

7. SWIMMING AND CHLORINE: PROTECTING YOUR SKIN AND HAIR
Water is one of the most important things for our bodies. In it's
most natural form that is. That in mind, one could think that swimming
-- immersing oneself in a pool of water-- is a healthy thing. The health
benefits of swimming are wonderful. However, the very things put in water
to protect us from infection are responsible for some adverse effects
on our skin, hair and even teeth. The primary enemy? Chlorine, a gaseous
greenish-yellow element used for its disinfecting power. There are ways
to combat this, as explained below.
One of the most common-- and obvious-- problems affects blondes. Blonde hair is known to turn green because of the exposure to copper (pipes)
and chlorine. Skin problems can also occur in frequent swimmers. If
you think about it, skin is the largest organ in the body. While technically
water-proof, the skin can absorb contaminants from water. While chlorine
is said to cause cancer and other ailments, problems to skin and hair
are usually not life-threatening. Irritation can occur on the skin and
scalp, making for a dry, itchy body and head. Additionally, the Pacific
Center for Health says that chlorine can also destroy much-needed proteins
in our bodies. Depleted of protein, skin and hair can become very dry. Hair can become unmanageable and color-treated hair can be ruined.
While swimming in a chlorinated pool can heighten the chances of
these affects, showering with a filter that remove the chemical can greatly
lower the effects of it. (This type of filter also helps in general for
households who also may have chlorine.) Also, wetting the hair with non-chlorinated
water prior to swimming will lessen that amount of the element that can
be absorbed. Also, there are several types of shampoo on the market,
such as UltraSwim, and pre-swim conditioning treatments that can help
keep hair healthy when swimming. Finally, although not the most attractive
accessory, bathing caps are well-suited from totally protecting hair-
and as noted above- can help protect blondes from becoming greens. For
those with long hair, caps can also help hair from dragging along during
laps! Post-swim, keeping up with hair can include shampooing, not using
the high setting on the blow dryer and using a wide-tooth comb instead
of a brush.
Chlorine isn't the only pool culprit. Water itself (ironically)
removes moisture from the skin. There is a layer of oil present on all
of our bodies, but once immersed in water, it disappears. This allows
for the dryness to set in. To combat this, after showering (following
the swim), apply a moisturizer- either a lotion or cream.
And a final tip about swimming and chlorine- don't swallow the
water! That could be a whole other article on the effects of that!
