Type |
Filtration
|
| |
Description |
Water filtration systems can use a
variety of filtration media to achieve
a clean water.
|
| |
Advantages |
- Reduce disagreeable
tastes and odors.
- cost effectiveness
- Retain beneficial minerals
- Balance & Stabilise pH
- Carbon filters are able to
remove organic material
(humus, algae),
concentrated chemicals
(chlorine, trihalomethane,
fluoride), and microscopic
contaminants (herbicides,
pesticides).
- No electricity cost
- Selected quality raw
materials for filtration
media
- Affordable & cost effective.
|
| |
Disadvantages |
- Only those good filtration system is effective in removing many common contaminants such as arsenic, bacteria, copper, lead, nitrates, parasites, sodium & viruses.
|
|
| 2. |
Type |
Reverse Osmosis
|
| |
Description |
This is a process that exposes water
under pressure to a semi permeable
membrane with a very fine pore
structure
|
| |
Advantages |
- Ability to reject nitrates,
chlorides ans some
contaminants
- The manual is simple and
secure
- No regeneration with
chemicals
- Low energy consumption
- Long lifetime of
membranes
|
| |
Disadvantages |
- Ineffective in removing
synthetic chemicals such
as herbicides and
pesticides because they
are smaller than the water
molecule and could pass
through the membrane.
- Reverse osmosis typically
wastes 2 to 3 gallons of
water for every gallon it
produces and costs 18 to
24 cents per gallon.
- R.O. systems require adequate water pressure
and extensive
maintenance.

|
| 3. |
Type |
Distillation
|
| |
Description |
Water is heated to boiling point
where it vaporizes. The vapor is
then condensed and stored after it
has been collected.
|
| |
Advantages |
- It is beneficial since it
takes away a wide range
of pollutants.
|
| |
Disadvantages |
- There could be other
harmful chemicals that
vaporize together with the
water and that could be
ingested assuming that the
water is purified.
- Uses too much energy.
- Slow process and it must
be repeated several times
to ensure significant water
purity.Synthetic chemicals
common in municipal
water such as pesticides,
herbicides, and chlorine
solutions won´t be
removed through
distillation, because their
boiling point is lower than
the one of water
- It strips water of its natural
trace elements, thus
turning it acidic as the
hydrogen composition
becomes greater in
proportion

| 4. |
Type |
UV Light / UV
Radiation
|
| |
Description |
Water passes through a
chamber where it is exposed
to UltraViolet radiation
|
| |
Advantages |
- Removes some organic contaminants
- Leaves no smell or taste in
the treated water
- Requires very little contact
time (seconds versus
minutes for chemical
disinfection
- Improves the taste of water
because some organic
contaminants and
nuisance
- Microorganisms are
destroyed
- Many pathogenic
microorganisms are killed
or rendered inactive.
- Does not affect minerals in
water
- This treatment is effective
against many bacterial
contaminants, but is not
effective in reducing
cryptosporidium
|
| |
Disadvantages |
- UV light is not effective against any non-living
contaminant, lead,
asbestos, many organic
chemicals, chlorine, etc.
- Tough cryptosporidia cysts
are fairly resistant to UV
light.
- Requires electricity to
operate. In an emergency
situation when the power is
out, it will not work.
- UV is typically used as a
final purification stage on
some filtration systems. If
you are concerned about
removing contaminants in
addition to bacteria and
viruses, you would still
need to use a quality
carbon filter or reverse
osmosis system in addition
to the UV system
- Decreases resistivity
- Will not remove particles,
colloids or ions.

Type |
Ionized Water System
|
| |
Description |
The Ionized Water System, slightly
is an electrical appliance connected
to your kitchen water supply to
perform electrolysis on tap water
before you drink it or use it in the
kitchen for cooking.
|
| |
Advantages |
- Removes dissolved
inorganics effectively
- Non-polluting and safe:
- No chemical regeneration
- No chemical disposal
- No resin disposal
- Inexpensive to operate
|
| |
Disadvantages |
|
|
| 6. |
Type |
Magnetization water
system
|
| |
Description |
Water is exposed to a strong
magnetic field and the properties of
water undergo a changes such as :
its physical properties like density,
viscosity, its chemical properties
like pH, and nitrogen iron
concentration undergo changes.
|
| |
Advantages |
- The small molecule
improve the taste of the
water and it can be rapidly
absorbed by tissues and
cells.
- The oxygen content of the
water is also increased
and the dissolution is
greatly enhanced.
- Improves taste & clarity of
water
|
| |
Disadvantages |
- The unit may cost some
money.
