Technical Comparison Between RO and Normal Water Purifier

The market is full of wide range of water purifiers, but before you decide on what are the best water purifiers for home use, do a comparative analysis of all the types available. There are water purifiers that use filtration techniques; there are electric ones and UV ones, apart from RO water purifiers. So, how does an RO water purifier differ from a regular one? Read on.

Hard water in your neighbourhood?

If your neighbourhood water supply is hard water, you would need a water purifier that is based on the principle of reverse osmosis, more commonly known as RO. Hard water has a high percentage of TDS or total dissolved salts which include fluoride, nitrates, arsenic, mercury, magnesium, calcium and iron. When you use one of the RO water purifiers, salts are separated from some of the heavier metals in the water. Still wondering how RO technology works? 

Reverse osmosis, and how it works

Reverse osmosis is the process wherein water is made to pass through a membrane at a high pressure. The natural process is osmosis but reverse osmosis is, as the name suggests, a process wherein water is made to pass against its natural flow. RO requires energy, and therefore there are electric pumps involved. This process cuts down all dissolved salts in the water and removes any kind of impurities. Water becomes free from all kinds of contaminants and becomes potable. The taste of water also improves, thanks to this reverse osmosis technology used in one of the RO water purifiers. These kinds of filters are the best water purifiers for home use, as typically most Indian urban environments depend on bore well water which has a lot of TDS.

Water purifiers with ceramic candles

One of the most commonly used basic water purifiers are those that use ceramic candles. These candles have tiny pores which filter contaminants. Although these normal water purifiers are based on the principle of filtration, the problem is that they are not very effective when it comes to dissolved chemicals. They also don’t make the water better to taste, as the salts don’t get removed. Basically, any non-electric purifier does not convert hard into soft or drinking water. 

ACG filters

Yet another typically used water purifier is known as activated carbon granules or ACG. Here, charcoal is used to remove any impurities in the water. However, it doesn’t work like RO water purifiers, and can’t remove salts or convert hard water into soft water. A disadvantage of this kind of filter is that it gets clogged rather quickly and needs constant replacement.

When you consider all these aspects, it can be concluded safely that the best water purifiers for home use are indeed RO water purifiers, especially if you live in conditions where hard water is available. 

So, choose the best water purifiers for home use, after checking out the specifications, warranty, after-sales service and ratings, for healthy living.
