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.

How
does water effect my teeth when I'm brushing?
"Every tooth
in a man's head is more valuable than a diamond" Miguel de Cervantes (1547-1616)
in Don Quixote.
The above
quote may sound funny, but Don Quixote was on to something. Healthy teeth
are essential to general health. Dental decay or caries, affects the majority
of populations in industrialized and many developing countries. It is
characterised by the dissolution of the dental enamel and dentine. This
eventually destroys the affected tooth surface or the tooth itself.
The immediate
cause is organic acid produced by micro-organisms present on the tooth.
Dental plaque consists of bacteria and a matrix of extracellular polysaccharides
produced from sucrose by the bacteria. Tooth plaque, specific bacteria,
diet, fluoride and saliva are all involved in the dental caries process.
In recent decades, preventive measures have helped to dramatically lower
levels of dental caries in industrialized populations. The most important
of these measures is exposure to an appropriate level of fluoride, from
various sources, including water, food and toothpaste.
Dental caries
is a multifactorial disease, related to:
- the presence
of microorganisms that cause caries, such as Streptococcus mutans, and
Streptococcus sobrinus
- fermentable
carbohydrates (e.g. sugars) in the diet, particularly when consumed
frequently
- susceptible
teeth, such as in the early stages of development, after injury or in
malnutrition or chronic disease
- time:
caries increase over time as teeth erupt and surfaces become at risk.
Good oral
health requires a clean water supply, sufficient for brushing and cleaning
teeth regularly from an early age. Poor oral hygiene may also result in
periodical problems since the dental plaque may induce gingival inflammation
and deep pockets.
While fluoride
intake from drinking water and a balanced, low sugar diet are probably
the most important factors in reducing dental caries, a lack of clean
water for basic oral hygiene may tip the balance towards earlier and more
severe patterns of caries. Where fluoride concentrations in water or in
the diet are known to be low, community water fluoridation is safe and
cost-effective. While there are established benefits from adding fluoride
to waters with low natural fluoride, fluorosis remains a problem in areas
of where the natural concentration of fluoride is high.
