What are Water Filters?
Water Filters remove unwanted impurities from water
such as sediment, taste and odour, hardness and bacteria
to result in better quality water. From producing better-
tasting drinking water to more specialist applications
such as brewing coffee and making crystal clear ice, we
offer a huge range of filters and cartridges to solve any
number of water-related issues.
There are many types od water filters for different
applications, such as
filter/">countertop water filter,
filter/">undersink water filter,
purifier/">commercial water purifier,
home
ro water purifier, filter/">tap filter,
shower
filter, NSF
filters, etc.
How Do They Work?
Water is one of the most important substances on the
planet, it covers 71% of the Earth’s surface and the
human body can contain as much as 75% of the stuff. Water
is vital to a huge number of applications including
agriculture, science, medical, transportation, heating,
recreation and food processing as well as washing and
perhaps most important of all: drinking.
For the majority of us, drinking water comes from a
treated municipal supply which is safe to drink but will
often feature unpleasant tastes and odours from chemicals
such as chlorine which are used to disinfect the water
and keep it free of germs and bacteria. Depending on
where you live, you may also find that your mains water
causes limescale deposits to form which can block pipes
and damage appliances. These issues, chlorine taste /
odour and limescale formation are just two among a host
of other common water problems which can be solved by
water filtration. But how do water filters actually work?
The basic idea of mechanical filtration is to
physically remove sediment, dirt or any particles in the
water using a barrier. Mechanical filters can be anything
from a basic mesh that filters out large debris to a
ceramic filter which has an extremely complex pore
structure for ultra-fine filtration of pathogenic
organisms. And a great water filter always worked
cooperated with a reverse osmosis system.
What is reverse osmosis?
Reverse osmosis removes contaminants from unfiltered
water, or feed water, when pressure forces it through a
semipermeable membrane. Water flows from the more
concentrated side (more contaminants) of the RO membrane
to the less concentrated side (fewer contaminants) to
provide clean drinking water. The fresh water produced is
called the permeate. The concentrated water left over is
called the waste or brine.
A semipermeable membrane has small pores that block
contaminants but allow water molecules to flow through.
In osmosis, water becomes more concentrated as it passes
through the membrane to obtain equilibrium on both sides.
Reverse osmosis, however, blocks contaminants from
entering the less concentrated side of the membrane. For
example, when pressure is applied to a volume of
saltwater during reverse osmosis, the salt is left behind
and only clean water flows through.
The reverse osmosis system can be devided into many
kinds with different characteristics like
system/">compact reverse osmosis system,
direct
flow ro system, change-ro-system/">quick change ro system and so on.
How does a reverse osmosis system work?
A reverse osmosis system removes sediment and
chlorine from water with a prefilter before it forces
water through a semipermeable membrane to remove
dissolved solids. After water exits the RO membrane, it
passes through a postfilter to polish the drinking water
before it enters a dedicated faucet. Reverse osmosis
systems have various stages depending on their number of
prefilters and postfilters.
