Choose the best Water Purifier For the Home

Regardless of how clean your drinking tap water looks, there is no guarantee that it’s pure and germ-free. It may have microscopic pathogens that cause diseases, new age contaminants like lead and arsenic or even a high degree 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 many regions in India, including cities like Mumbai, Delhi, Bangalore.

You might think that boiling your water before you drink it’s good enough. However, this is far from the truth. Boiling only provides protection against microbial contamination caused by bacteria, virus, etc. it generally does not remove dangerous chemicals/new age contaminants like lead, pesticides and physical impurities like mud, dust, rust, etc.

So what’s it that you can certainly do to ensure that the quality of drinking tap water your household gets is pure and safe?

Many families are looking at water purifiers to ensure that their drinking tap water is safe and healthy. But, with the market flooded with an array of brands just how do do you know what water purifier to select?

A 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 water purifier UAE. Once you understand this you understand what type of water purifier you need to buy. Here’s things you need to understand about the various technologies for sale in the market.

Reverse Osmosis

If your home is 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 properly used as long as the amount of Total Dissolved Salts in water is very high.

RO (Reverse Osmosis) works by making use of high strain on the water based on the amount of salt content; it’s 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 a lot more than 90% of the TDS and all impurities within the water. These impurities could range from bacteria, virus, protozoa, cysts, coliform, physical and chemical contaminants etc.

UV

UV water purifiers are ideal in areas where you obtain soft water that way from rivers or lakes and where the TDS level is below 500mg.

In purifiers that use UV purification, a light is employed to produce UV rays to that your water is exposed. The UV rays penetrate in to the microorganism and alter its DNA, once this is completed then it is actually killed and can’t cause any infection or even reproduce! This technique destroys about 99.99% of organisms that cause diseases!

These purifiers do not change the chemical composition of the water or alter its taste. As it doesn’t alter the chemical composition of water it can not be used in areas where you obtain hard water.

Carbon Adsorption

When water is passed within the carbon surface the contaminants are drawn to the surface. The carbon is processed to make it extremely porous, this allows a sizable surface 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 quite effective against getting rid of pesticides, herbicides, chlorine, radon and other chemicals. The caliber of these filters are rated by how big particles so it can remove. A filter that measures 0.5 micron is far better than the one which measures 10 microns.

Ultra filtration (UF)

This technique of purification removes dissolved solids involving 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 can be 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.

Ionization

This technique of purification is ideal if your home is 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 top and dissolves the sodium. The calcium, magnesium and other cations precipitate to 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 usually incorporated into water purifiers as well as other methods.

When you are purchasing a water purifier make 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, ensure that you family drinks water that’s pure and safe.
