Features of a Water Purifier

No matter how clean your drinking water seems, there is not any certainty that it is pure and germfree. It might have microscopic pathogens which lead to diseases, fresh era contaminants like lead and arsenic along with some very high amount of TDS (Total Dissolved Salts).

Around 8 main cities in India, drinking water-borne diseases like cholera, jaundice and typhoid accounted for around 77 percent percentage of most of the diseases in India. The survey also threw light onto how the TDS levels are way above the permissible amount in many regions in India, including cities like Mumbai, Delhi, Bangalore.

You might think that boiling your drinking water before you drink it is fine enough. However, this is far from the facts. Boiling simply provides protection against microbial contamination caused by bacteria, virus, etc. it will not eliminate dangerous chemicals/new era contaminants like lead, pesticides and physical impurities like mud, dust and rust, etc..

So what is it that you are able to do in order to guarantee that the quality of drinking water that your family gets is pure and safe?

Many families are turning to water purifiers to be certain that their drinking water is safe and healthy. But, with industry flooded with an array of makes how do you know what water filter to choose?

A little bit of research is all you need before you purchase your water purifier. The first and most important thing that you will need to learn is exactly what your water condition is. Once you know this do you know very well what kind of water purifier that you ought to purchase. Here is the thing you want to know concerning the various technologies available in the marketplace.

Reverse Osmosis

If you live in an area where you get hard-water then RO water purifiers are ideal. If the TDS (Total Dissolved Salt) degrees in your own water transcend the permissible limit then it poses a serious danger to your health. RO water purifiers reduce the TDS material in your own water to your own permissible level and must be utilized only if the level of Total Dissolved Salts in warm water is very high.

RO (Reverse Osmosis) functions applying high strain on the drinking water depending on the amount of salt material; it is then forced through a 0.0001 micron, semi-permeable membrane. RO allows cross filtration of water, exactly where the contaminants are caught in the system. The impure water moves one way and the wash water moves another manner. The cross filtration allows the impure water to sweep away the contaminants with it thus, preventing a build up.

Typical RO purifiers eliminate greater than 90% of their TDS and all impurities present in the drinking water. These impurities can range from bacteria, virus, protozoa, cysts, coliform, physical and chemical contaminants etc..


UV water purifiers are ideal for areas in which you get soft drinking water like which from rivers or rivers lakes and at which the TDS degree is under 500-mg.

In purifiers which use UV purification, a lamp is utilized to create ultra violet beams to which the drinking water is subjected. The ultra violet rays penetrate into the microorganism and alter its DNA, once this is done then it is essentially killed and can’t lead to an infection and sometimes maybe reproduce! This procedure destroys roughly 99.99 percent of most organisms which cause diseases!

These purifiers do not alter the chemical composition of the drinking water or change its particular taste. Since it willn’t alter the chemical composition of plain water it can’t be utilized in areas at which you obtain hard H20.

Carbon Adsorption

When water is handed over the carbon surface the contaminants are drawn to your outer lining. The carbon is processed to make it extremely porous, this provides a large surface area for adsorption or chemical reactions. These carbon filters normally use granular carbon or carbon blocks of powdered carbon. It is a commonly used engineering and is quite effective in getting rid of pesticides, herbicides, chlorine, radon and other chemicals. The quality of the filters is rated with the size of particles that it may take out. A filter that actions 0.5 micron is more effective than the one that steps 10 microns.

Extremely filtration (UF)

This method of purification removes dissolved solids in between your sizes of 0.005-0.1 microns. A lot of times it is used as a pre- treatment step previous to Reverse Osmosis (RO). The extremely filtration system works as a molecular sieve plus it divides molecules dependent on the size. The drinking water enters 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 entire filter. They function in places where in fact the TDS level is 500 mg/liter.


This procedure of purification is ideal if you live in a region in which you obtain hard H20. To convert hard water to soft water, the more water is passed over an ion exchange resin. Drinking water flows across the surface also dissolves the sodium. The calcium, magnesium and other cations precipitate onto the surface. Ion-exchange can lessen hardness in the drinking water. It can also get rid of contaminants like iron, aluminum, lead, barium, radium, and nitrates. This tech is often integrated into water purifiers along with other strategies.
