RO Water Purifier

How To Choose A Water Purifier For Your Home?

Even the cleanest drinking water is no guarantee that it is clean and bacteria-free. It may contain tiny disease-causing pathogens, new-age contaminants such as lead and arsenic, or very high levels of TDS (total dissolved salts).

In eight large cities in India, 77% of all water-borne diseases, such as cholera, jaundice and typhoid, are water-borne. The report also shows that TDS levels are well above acceptable levels in many parts of India, including cities such as Mumbai, Delhi and Bangalore.

You may think it’s enough to boil water before drinking it. But this is far from the truth. Boiling only provides protection against microbial contamination caused by bacteria, viruses, etc. It cannot remove dangerous new-age chemicals/pollutants such as lead, pesticides or natural pollutants such as dirt, dust and rust.

So, what can you do to make sure the drinking water your family receives is clean and safe?

Many families use a RO water purifier to ensure safe and healthy drinking water. However, with so many brands on the market, it can be difficult to know which water purifier to choose.

Before buying a water purifier, you should do some research. First, and most importantly, you need to know what kind of water you have. Once you know this, you will understand what kind of water purifier you should buy. Here are some of the different technologies available on the market.

Reverse osmosis Water Purifier

If you live in an area with hard water, a reverse osmosis water purifier is the ideal choice. Reverse osmosis water purifiers reduce the concentration of TDS in the water to an acceptable level and should only be used if the concentration of TDS in the water is too high.

RO (reverse osmosis) is a system that applies a high pressure depending on the salinity of the water, and the water passes through a semi-permeable 0.0001-micron membrane. Reverse osmosis allows the water to filter, allowing contaminants to pass through the membrane. Impure water goes one way and clean water the other. Cross-filtration purifies impure water and prevents contaminants from accumulating.

A typical reverse osmosis water purifier removes over 90% of TDS and all impurities from water. These impurities can include bacteria, viruses, protozoa, cysts, coliforms, as well as physical and chemical contaminants.

Ultraviolet light

Ultraviolet light water purifiers are ideal in areas where there is soft water from rivers and lakes or where the TDS value is less than 500 mg.

In the case of an ultraviolet water purifier, ultraviolet light is produced by a lamp that illuminates the water. The UV light penetrates the micro-organisms and changes their DNA. The micro-organisms are thus essentially killed and can no longer cause infection or multiply. This method kills about 99% of micro-organisms. This method kills approximately 99.99% of all pathogenic micro-organisms.

These purifiers do not change the chemical composition of the water or its taste. Since it does not change the chemical composition of the water, it cannot be used in hard water areas.

Carbon adsorption

When water passes over a carbon surface, contaminants are attracted to the surface. The carbon is treated to be highly porous; this provides a large surface area for adsorption or chemical reactions. These carbon filters typically use granular carbon or powdered carbon blocks. This is a commonly used technology that is very effective in removing pesticides, herbicides, chlorine, radon and other chemicals. The quality of these filters is judged by the size of the particles they can remove. A 0.5-micron filter is more effective than a 10-micron filter.

Ultrafiltration (UF)

This treatment method removes dissolved solids of size 0.005-0.1 microns. It is often used as a pretreatment step prior to reverse osmosis (RO). The ultrafiltration membrane functions as a molecular sieve and separates molecules by size. The water passes through an extremely fine filter, which retains most of the macromolecules above a certain size, such as colloids, microorganisms, etc. Smaller molecules, such as water, are separated by molecular size. Smaller molecules, such as solvents, pass through the filter. They work best in areas where the TDS level is below 500 mg/liter.

Ionization

This purification method is ideal if you live in a hard water area. To transform hard water into soft water, water is passed through an ion exchange resin. The water flows over its surface and dissolves the sodium. Calcium, magnesium and other cations precipitate on the surface. Ion exchange can reduce water hardness. It can also remove contaminants such as iron, lead, copper, barium, radium and nitrates. This technology is often integrated into water purifiers along with other methods.

When purchasing a water purifier, make sure it is certified by an accredited body, such as NSF, WQA and FDA.

With all this information, you can confidently choose a water purifier that meets your needs. Now make sure your family drinks clean, safe water.
