Regardless of how clean your normal water looks, there’s no guarantee that it’s pure and germ-free. It might have microscopic pathogens that cause diseases, new age contaminants like lead and arsenic or perhaps a quite 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 of the diseases in India. The survey also threw light on the fact 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 before you drink it’s good enough. However, that is definately not the truth water filter system Dubai. Boiling only provides protection against microbial contamination due to 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’s it that you can do to make sure that the quality of normal water your family 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 the market flooded with an array of brands how do do you know what water purifier to decide on?
A little research is all you have to before you buy your water purifier. The very first and foremost thing you need to know is what your water condition is. Knowing this you realize what sort of water purifier you will need to buy. Here’s what you need to learn about the various technologies for sale in the market.
If your home is in a location 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 decrease the TDS content in your water to a permissible level and should be utilized only if the degree of Total Dissolved Salts in water is extremely high.
RO (Reverse Osmosis) works by applying high pressure on the water based on the degree 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 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 this from rivers or lakes and where the TDS level is below 500mg.
In purifiers that use UV purification, a lamp is employed to produce UV rays to that the water is exposed. The UV rays penetrate into the microorganism and alter its DNA, once this is performed then it is basically killed and can’t cause any infection as well as reproduce! This method destroys about 99.99% of organisms that cause diseases!
These purifiers don’t change the chemical composition of the water or alter its taste. As it doesn’t alter the chemical composition of water it cannot be found in areas where you obtain hard water.
When water is passed over the carbon surface the contaminants are attracted to the surface. The carbon is processed to make it extremely porous, this provides a big surface area for adsorption or chemical reactions. These carbon filters normally use granular carbon or blocks of powdered carbon. It is a commonly used technology and is very effective against eliminating 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 more effective than one that measures 10 microns.
Ultra filtration (UF)
This method 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 on the basis of the size. The water passes through an extremely fine filter which retains most macromolecules which are above a specific 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 method of purification is ideal if your home is in a location 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 on to the surface. Ion-exchange can reduce hardness in the water. It may also remove contaminants like iron, lead, copper, barium, radium and nitrates. This technology is usually incorporated into water purifiers along with other methods.
When you are investing in 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 are able to safely step out and choose a water purifier that suits your needs. Now, ensure that you family drinks water that’s pure and safe.
