Whole House Filtration
These are usually two-stage filtration systems.
The first stages of shower filter dubai
traps particles larger than 10 to 100 microns in size, and the second stage
traps smaller particles. This arrangement allows a much longer useful lifetime
for the finer membrane (and more expensive) second stage filter. Unlike
softening systems, filtration systems filter out all particles larger than the
membrane rating of the second filter. This means they remove metals, non-metals
and biological particles such as bacteria. All filtration systems will require
as much or more maintenance (back-washing, filter replacement, etc.) as the
most maintenance-intensive water softening systems. The more effective systems
have higher installation costs than the most expensive softening systems, as
well.
Filtration
Ratings
The effectiveness of a filtration system is based
on the smallest size particles it removes from water. The more particles
removed, the higher the cost. Cloth and Depth filters will remove particles
larger than 10 micron (100,000 angstroms). This includes contaminants such as
sand, pollen and larger Giardia. Microfilters are rated from 10 micron down to
1/100 micron. Filters rated below 1/10 micron will remove bacteria as well as
both Cryptosporidium and Giardia (two pathogens targeted by municipal treatment
plants). The finest microfilters will also remove most colloidal metals from
water. The highest commonly available level of filtration is Reverse Osmosis
(RO) filtration. These systems are rated between 1/1,000 micron and 1/10,000 (1
angstrom). Although expensive ($10,000 and up) to install, RO systems remove
viruses, dissolved organics and even metal ions from water filter dubai.
Trade-offs
Home water purifier uae and treatment systems are available
to remove anything from metal particles through metal ions from incoming water.
They may add salts or potassium into the system, which is a health concern, or
they may remove beneficial metals and fluorides from the water along with
pathogens. In general, filtration systems are more expensive to install and
maintain than softener systems.If the need is simply to make the water less
hard, softening systems will be more cost effective. However, if there are
additional water quality concerns such as waterborne pathogens or bad taste,
softening systems will not address those problems.
When making the choice between of water filter dubai softener system and a whole-house
system, the main question to be answered first is: what is the quality of the
incoming water? Most municipal and rural systems take ground water (wells) as
the primary source water. This water tends to have higher percentages of
dissolved minerals than surface water. High mineral content is commonly
referred to as hard water. Water softeners concentrate on removing minerals
from water. Whole house filtration systems address a broader spectrum of water
quality issues.
Water
Softening
The most common water purifier dubai softening systems are salt-based
systems, which replace hard water minerals with salt ions. Also common are
non-salt softening systems which do not add salts to the water but are
vulnerable to even trace amounts of oil or hydrogen sulfate. For small volume
uses, magnetic systems will pull metallic minerals from water.
Softener
Advantages and Disadvantages
Salt-based water softeners add sodium (and some
potassium) to the water. They require regular maintenance, including restocking
consumable salt, and are in the $1,000 to $3,000 range to install. Non-salt
systems require less maintenance and shower filter dubai start around $1,500 but
are damaged by trace amounts of oil. Magnetic systems have the least
maintenance expense; can be installed for under $1,000 but have no effect on
non-metallic dissolved materials.
