Water
is the one of vital for human survival. It serves the following functions to
the human body namely making up water lost via breathing, perspiration,
digestion and urination, regulating body temperature, transporting nutrients to
body cells, removing waste from the body and protecting organs, tissues and
joints. We need to re-hydrate by drinking water and other beverages.
The
main sources of water are rivers, lakes, reservoirs, ground water and the sea.
The water from these sources at times could not be consumed right away. It
needs to go through water treatment processes before we could consume it. The
reason is that it could be contaminated with pollutants like suspended solids,
algae, bacteria and viruses.
Water
goes through different processes like screening, rapid mixing, sedimentation,
flotation, filtration, micro-screening, disinfection, de-chlorination etc. in
the treatment plant. After these processes, suspended solids, micro-organisms
and bacteria are eliminated according to the required specification. The end
result is water that is safe for drinking purposes.
Before
we are able to drink water from the treatment plant, it has to be delivered to
our houses and offices. During the delivery through the pipe line from the
treatment plant or its storage area, the drinking water may be contaminated
again with mud and suspended solids due to pipe leakage and repair works, heavy
metals from pipe corrosion as well as bacteria and viruses originated from dirty
storage tank.
Hence,
when the water comes out from the tap, it may be still contaminated with
suspended solids, bacteria, viruses and heavy metals like lead and iron which
could affect adversely our body.
The
best way to get good quality drinking water:
It
is advisable to treat the water from the tap one more time before consumption.
Most
of us choose to boil it. Boiling can kill the bacteria. However, it can
activate the chemical reaction between chlorine and other pollutants. The more
often you boil the tap water, the more intoxicated it becomes.
An
advisable way to treat the tap water is to use a water filter or purifier to
screen the pollutants before consumption. A good water filter could screen
almost 100% of the suspended solids, minerals, bacteria and viruses. The end
result is pure water containing no suspended solids, bacteria, viruses and
minerals. It could be consumed at the ambient temperature, cooled or heated
before drinking. It tastes good and refreshing. Even you boil it, it will not
get intoxicated. Therefore, water filter produces good quality drinking water.
