Let us explore different techniques used for purifying the
water and their aptness. These techniques basically depend on the source of
water, the nature and amount of impurities in it, and its TDS levels.
First method is the Reverse Osmosis method that is used to
get rid of the dissolved solids of and over the size 0.0009-0.007 microns by
means of a semi-permeable membrane. In addition to making the water pure, it is
also desalinated and the TDS of water is decreased by about 90 percent. In case
you are getting the water from borewell or the water supplied is salty and hard
with TDS levels exceeding 500 mg/liter, RO water purifier is the best choice.
UV (Ultra Violet) purification is another technique that puts
to use the UV rays of the sun for the purpose of purifying water. These rays
are casted by a refined lamp, in fixed quantities. This technique destroys all
water-borne, disease-causing germs and provides clean and sterilized drinking
water by keeping the minerals present in the water intact. In general, the UV
purifiers involve three or four purification phases, activated carbon cartridge
and sediment filter being the most essential ones. These are ideal for the tap
water that is pre-treated and has a normal taste.
Nanofiltration eradicates the dissolved solids from water
that are of and greater than the size of 0.0009-0.007 microns. In addition to
the solids, viruses and bacteria in the water are also removed. Another method
of water purification is the Ultrafiltration in which the dissolved solids of
the size 0.005-0.1 microns and more than this size are cleared away. Thus,
taking into account your requirements, you must always buy the appliances like
water purifier as well as gas stove
and other home appliances.
