REVERSE OSMOSIS WATER PURIFIERS
Of all the water purifier system types on the market by far the most superior is the reverse
osmosis process.
Reverse osmosis works by forcing water through a membrane, if the water molecule is
small enough it will pass across the membrane material and into the product line (pure
water). A water molecule is 2 parts hydrogen and 1 part oxygen (H
2
O) but if a molecule
had extra atoms attached the molecule is larger and won’t pass through the membrane
and is rejected, the contaminated molecule then goes into the waste line and is ejected
from the system.
The term “waste water” is not a kind way of describing the contaminated (waste) water
that is rejected by the reverse osmosis as it is water that is contaminated in some way and
not simply waste as such, the reverse osmosis process is a selection process, if the water
molecule is pure it will pass into the pure water part, anything else is rejected.
The reverse osmosis process is the best water purity of any type of process and is similar
to Distillation but distilled water is almost devoid of oxygen and tastes flat and dead,
reverse osmosis water process actually adds oxygen to the water resulting in extremely
pure sweet tasting water with almost all the poisons and impurities removed.
Waste Water
The PSI-021-4PC is designed for simple installation and operation and is well within the
abilities of a home handyman to maintain, the filters should be changed at the
recommended service intervals to maintain continual un-troubled service life.
