Water is found in its purest form where it originates, but from then on water flows across different places and gets mixed up with rainwater, dust, soil, and other impurities before it gets poured into your glass. So, water becomes unfit for consumption because it contains different types of impurities.

In fact, even the borewell water can't be considered clean because the groundwater which seeps in through the Earth's surface gets mixed with dissolved solids, minerals, and other pollutants.

Hence, the water needs to be purified to make it portable and you can hardly use the untreated water for drinking purposes.

Usually, the bore water or the groundwater is hard because it contains high levels of TDS. Normal water purifiers or water filters can't remove TDS from the water. You need RO water purifiers to eliminate the TDS and treat the water to make it fit for drinking.

Since bore water is one of the main sources of water for many, having a RO purifier at home has become inevitable.

So, we'll learn more about RO and how does it work?

What is RO?

Reverse Osmosis is one of the advanced and effective water purification technologies. It is used to remove a lot of harmful contaminants from the water. RO ensures to eliminate even the minute particles and deliver clean and safe drinking water.

In recent years, the quality of water has been affected by several factors, as a result, the water is high in TDS levels. The bore water contains more TDS as it has more impurities like heavy metals, excess minerals, chemicals, and even biological impurities.

A normal water filter can only remove some impurities from the water. It doesn't completely clean the water. Hence, RO is one of the most preferred techniques to treat such impure water.

How does RO work?

RO or Reverse Osmosis is effective because it uses a semipermeable membrane to extract all the harmful contaminants from the water. It purifies even the tiniest particles and ensures to deliver completely clean water.

RO happens in three distinct stages:

Pre-Filtration Stage:

The pre-filtration stage consists of two stages of purification: Sediment Filter and Carbon Filter.

Sediment Filter: It constitutes the primary stage of water purification in RO water purifiers. The main function of a sediment filter is to remove clay particles, dirt, and dust particles from the water.

Carbon Filter: The Carbon Filter removes Chlorine, organic compounds, and reduces bad odor or taste from the hard water. When the water is high in TDS levels then it is usually hard in nature and can have a sour taste or bad smell. Hence, a Carbon Filter removes these types of impurities in water.

RO Purification Stage:

The RO purification process is an important stage of purification. It is equipped with an RO membrane that contains small pores through which only the water molecules can pass through. When the water molecules are passing through the RO membrane, these pores will trap all the impurities like heavy metals, suspended particles, microorganisms, bacteria, viruses, and chemicals releasing the clean water into a post-filtration stage.

Post-Filtration Stage:

UV water filter: After the RO purification, most harmful pollutants are removed from the water. However, some bacteria and viruses may still pass through the membrane. In this case Ultraviolet purification process helps in killing the remaining bacteria and viruses present in the water.

When Do You Need an RO Purifier?

Mostly, the TDS levels in rivers or lakes are below 200 ppm. However, the TDS levels in bore water are high, i.e. more than 500 ppm. If your home tap water contains TDS of more than 500ppm, then you should opt for RO water purifiers. The water with a TDS level lower than 200ppm requires a normal or UF water purifier.

Benefits of RO Purifier

1. Removes all impurities from the water: RO purifiers remove heavy metals, chemicals, biological pollutants, and pathogens present in the water. RO is one of the safest water purification systems which purifies water without adding any chemicals during the process.
2. Reduces the hardness in water: The water with high TDS levels is usually hard in nature. RO purifiers help by reducing the hardness in the water.
3. Changes in the taste of water: Usually, river waters are naturally sweet, and they don't need a purifier to sweeten the taste. The water in borewells or groundwater is not always sweet, they are either salty or sour which makes it difficult to drink. RO purification will eliminate the salt and bring sweetness to the water.

Conclusion

RO water purifiers are common in India, mainly because of the quality of drinking water. Hence, many people prefer RO water purifiers at home to access clean and safe drinking water. If you are looking for a water purifier, consider the factors such as TDS, water quality, budget, and purification systems before buying a water purifier.

You can always rely on brands like Pureit for good-quality and advanced water purifiers. In fact, you can also find a combination of purifiers like RO + UV + UF water purifiers and so on. Choose the criteria and opt for a suitable water purifier for your home and ensure good health and immune system.
