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.

5. DRINKING WATER AND WEAK IMMUNE SYSTEMS
Contaminated water could be harmful to anyone, even more so for
those with weakened immune systems. In fact, some organisms that could
show up in water may be harmless to most, but deadly to others. A weakened
immune system can be a result of having an organ transplant, having HIV
or AIDS or from undergoing chemotherapy. A weaker immune system means
a higher likelihood of contracting disease from waterborne contaminants.
Cryptosporidiosis, a diarrhea disease known better as "crypto",
is one ailment caused by a microscopic parasite that can have a greater
affect on a weakened immune system. In fact, over the past 20 years,
it has become one of the more common waterborne illnesses. Cryptosporidium
parvum lives in intestines of humans and animals and is passed in their
stool. This disease is communicable and can be passed by water, sex, sharing
food and even touching farm animals. The parasite is protected by an
outer shell, which allows it to survive outside the body for long periods
of time and-- here's the kicker-- makes it very resistant to chlorine
disinfection. The parasite is found in every region of the United States
and throughout the world in drinking and recreational water. The illness
can last a few days to a week in a normal person, but for someone with
AIDS, it can be fatal. Ironically, with something you catch from water,
water is a huge cure for this. With diarrhea, people become very dehydrated. Drinking clean, pure water is a way to get back to health. However, once
inflicted, the disease can recur. The best prevention is to practice
safe water practices. Most important, this means clean drinking water. The Center for Disease Control states on their website that all reverse
osmosis filters protect the best against crypto. Some other filters may
work, but they must say "absolute 1 micron" to be sure.
Another disease to be aware of is toxoplasmosis-- a disease from
a single-celled parasite toxoplasma gondii. It is noted that there are
over 60-million people who are infected with this disease-causing parasite,
however most immune systems fight off an illness before symptoms arise,
the parasite lying dormant. But for those with weaker immune systems,
it's not that easy. According to the Center for Disease Control, those
with weak immune systems should ask their doctors about getting a blood
test for toxoplasma. If results are positive, doctors can inform the patient
if and when medicine should be taken to prevent the infection from reactivating.
A negative test means the person was never infected. But- precautions
need to be take to avoid infection. Warning signs of toxplasmosis include
flu-like symptoms and achy muscles. In a healthy person, the "bug" will
work its way out. In rarer cases, brain, nerve and eye damage can result. If this disease rings a bell, you may recall it as something pregnant
women are cautioned about as well-- the parasite is also found in cat
feces and those carrying babies are urged not to changed the litter.
These are just two major diseases that can affect someone with
a weak immune system. Since the immune system can't work as hard to protect
you from water contaminants, let a water filter do it for you. It could
be the only way to be 100% sure crypto stays out!
