Regardless how clean your drinking tap water looks, there is no guarantee it is pure and germ-free. It might have microscopic pathogens that cause diseases, new age contaminants like lead and arsenic or perhaps a high level of TDS (Total Dissolved Salts).
Across 8 major cities in India, water- borne diseases like cholera, jaundice and typhoid accounted for 77% percent of all diseases in India. The survey also threw light on the truth that the TDS levels are way above the permissible level in several regions in India, including cities like Mumbai, Delhi, Bangalore.
You may think that boiling your water when you drink it is good enough. However, this really is not even close to the truth. Boiling only provides protection against microbial contamination brought on by bacteria, virus, etc. it doesn’t remove dangerous chemicals/new age contaminants like lead, pesticides and physical impurities like mud, dust, rust, etc.
So what is it that you certainly can do to ensure that the caliber of drinking tap water your family gets is pure and safe?
Many families are turning to water purifiers to ensure that their drinking tap water is safe and healthy. But, with the marketplace flooded with a plethora of brands how can guess what happens water purifier to choose?
A little research is all you have to before you decide your water purifier. The first and foremost thing you have to know is what your water condition is. Once you understand this you realize what kind of water purifier you will need to buy. Here’s things you need to know about the many technologies available in the market.
If you reside in a place where you obtain hard water then RO water purifiers are ideal. If the TDS (Total Dissolved Salt) levels in your water exceed the permissible limit then it poses a significant threat to your health. RO water purifiers reduce steadily the TDS content in your water to a permissible level and should be utilized only when the degree of Total Dissolved Salts in water is quite high.
RO (Reverse Osmosis) works by making use of high stress on the water according to the degree of salt content; it is then forced through a 0.0001 micron, semi-permeable membrane. RO allows cross filtration of water, where the contaminants are caught in the membrane. The impure water goes one way and the clean water goes another way. The cross filtration allows the impure water to sweep away the contaminants with it thus, preventing a build up.
Typical RO purifiers remove more than 90% of the TDS and all impurities present in the water. These impurities could range between bacteria, virus, protozoa, cysts, coliform, physical and chemical contaminants etc.
UV water purifiers are ideal in areas where you obtain soft water like that from rivers or lakes and where the TDS level is below 500mg.
In purifiers that use UV purification, a light is employed to create UV rays to that the water is exposed. The UV rays penetrate in to the microorganism and alter its DNA water filter system Dubai, once this is performed then it is essentially killed and can’t cause any infection as well as reproduce! This method destroys about 99.99% of most organisms that cause diseases!
These purifiers do not change the chemical composition of the water or alter its taste. Because it doesn’t alter the chemical composition of water it cannot be used in areas where you obtain hard water.
When water is passed over the carbon surface the contaminants are interested in the surface. The carbon is processed to create it extremely porous, this provides a big area for adsorption or chemical reactions. These carbon filters normally use granular carbon or blocks of powdered carbon. It is just a commonly used technology and is very efficient against eliminating pesticides, herbicides, chlorine, radon and other chemicals. The caliber of these filters are rated by the size of particles so it can remove. A filter that measures 0.5 micron is more effective than the one which measures 10 microns.
Ultra filtration (UF)
This method of purification removes dissolved solids between the sizes of 0.005-0.1 microns. Many a times it is used as a pre- treatment step before Reverse Osmosis (RO). The Ultra filtration membrane works as a molecular sieve and it separates molecules on the basis of the size. The water passes via an extremely fine filter which retains most macromolecules which are above a certain size like colloids, microorganisms etc. Smaller molecules like solvents pass through the filter. They work best in areas where the TDS level is below 500 mg/litre.
This method of purification is ideal if you reside in a place where you obtain hard water. To convert hard water to soft water, the water is passed over an ion exchange resin. Water flows over the outer lining and dissolves the sodium. The calcium, magnesium and other cations precipitate onto the surface. Ion-exchange can reduce hardness in the water. Additionally it may remove contaminants like iron, lead, copper, barium, radium and nitrates. This technology is generally incorporated into water purifiers along with other methods.
When you’re investing in a water purifier be sure that it is certified by an accredited body such as the NSF, WQA and FDA.
Armed with all these details you are able to safely step out and choose a water purifier that suits your needs. Now, ensure that you family drinks water that is pure and safe.
