Regardless of how clean your normal water looks, there is no guarantee it is pure and germ-free. It may have microscopic pathogens that cause diseases, new age contaminants like lead and arsenic or even a very good 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 lots of regions in India, including cities like Mumbai, Delhi, Bangalore.
You may be thinking that boiling your water when you drink it’s good enough. However, this really is definately not the truth water purifier Dubai. Boiling only provides protection against microbial contamination caused 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 can certainly do to make sure that the caliber of normal water your household gets is pure and safe?
Many families are turning to water purifiers to make sure that their normal water is safe and healthy. But, with industry flooded with a plethora of brands how can guess what happens water purifier to select?
A little bit of research is all you want before you buy your water purifier. The first and foremost thing you need to find out is what your water condition is. Knowing this you know what type of water purifier you’ll need to buy. Here’s what you need to know about the various technologies for sale in the market.
If you reside in an area where you get 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 the TDS content in your water to a permissible level and should be properly used as long as the degree of Total Dissolved Salts in water is quite high.
RO (Reverse Osmosis) works through the use of high stress on the water based on the degree of salt content; it’s then forced via 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 of the ways 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 contained 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 get soft water like this from rivers or lakes and where the TDS level is below 500mg.
In purifiers that use UV purification, a lamp is employed to create UV rays to that your water is exposed. The UV rays penetrate to the microorganism and alter its DNA, once this is done then it is essentially killed and can’t cause any infection as well as reproduce! This approach destroys about 99.99% of all organisms that cause diseases!
These purifiers don’t change the chemical composition of the water or alter its taste. Because it doesn’t alter the chemical composition of water it can’t be used in areas where you get hard water.
When water is passed over the carbon surface the contaminants are drawn to the surface. The carbon is processed to produce it extremely porous, this allows a sizable 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 effective against removing pesticides, herbicides, chlorine, radon and other chemicals. The quality of these filters are rated by the size of particles that it can remove. A filter that measures 0.5 micron is far better than the one which measures 10 microns.
Ultra filtration (UF)
This approach of purification removes dissolved solids between the sizes of 0.005-0.1 microns. Many a times it’s used as a pre- treatment step before Reverse Osmosis (RO). The Ultra filtration membrane works as a molecular sieve and it separates molecules based on the size. The water passes through an extremely fine filter which retains most macromolecules which are above a certain size like colloids, microorganisms etc. Smaller molecules like solvents move across the filter. They work best in areas where the TDS level is below 500 mg/litre.
This approach of purification is ideal if you reside in an area where you get hard water. To convert hard water to soft water, the water is passed over an ion exchange resin. Water flows over the surface 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 get rid of contaminants like iron, lead, copper, barium, radium and nitrates. This technology is generally integrated into water purifiers along with other methods.
When you’re investing in a water purifier be sure that it’s certified by an accredited body like the NSF, WQA and FDA.
Armed with all these details you can safely step out and choose a water purifier that suits your needs. Now, make sure that you family drinks water that is pure and safe.Business
