Stages of Water Filtration Process in an RO Purifier

There is no single filtration process that can remove every type of impurities, therefore, we need multi-stage RO water filtration process. The selection of an RO water purifier is based on two factors: the level of impurities present in your drinking water and your personal preference. Below mentioned are essential filtration stages that an RO water purifier actually need.

An RO water purifier should have a sediment filter, activated carbon filter, RO filter, UV filter, UF filter, Mineral retention process and finally Post carbon filter. Let us study briefly about each of the filtration processes.

  • Sediment Filtration: 

Supplied or tap water might contain different types of impurities like dirt, rust, chemicals, VOC and other impurities. To remove such impurities, sediment filter is used in the first stage of filtration process of the RO water purifier. In this stage, the filter acts as a blockage to remove all the solid impurities from the water.

  • Activated Carbon Filtration:

The supplied water might contain a lot of chemical impurities and bad smell, so in order to get rid of these, RO purifier comes added with an activated carbon filter. The activated carbon is mainly used for removing the organic constituents and residual disinfectants in the water supply. This filter can also improve the taste of water and help in minimizing the health hazards. It can also filter out the bad odor and color of the water and make it potable.

  • RO Filtration:

Reverse osmosis (RO) is the best process of purifying water that mainly uses the semipermeable membrane to remove ions, molecules, and larger particles from the feed water. During this process, an applied pressure is used to remove the suspended impurities from water, including bacteria, and provide you potable water. With the reverse osmosis filtration technology, impurities like Fluoride, Lead, Chlorine & Chloramine, Pesticides Detergents, Nitrates, and Sulphates are removed. It is due to the applied pressure the impurities get filtered out and what is left is clean, tasty and pure drinking water.

  • UV Purification:

This is another process of water purification that perfectly deactivates the microorganisms in water and makes it 100% free from pathogens. In UV purification process, high power ultraviolet lamp is used through which the feed water is passed. The process kills the harmful micro-organism like bacteria, virus, and cysts from the water by attacking the genetic core. The ultraviolet light destroys the illness-causing microorganisms by attacking the DNA at their genetic core. It also eliminates 99.99% of harmful viruses and bacteria and even stops the ability to reproduce.

  • UF Filtration

Ultrafiltration is the next stage in RO water purifier that has a semipermeable membrane, which is capable of removing germs and viruses from the water. It can also clean the muddy water and can purify all the dirt present in it.

  • Mineral Retention

Minerals are very necessary for our body, but during the reverse osmosis purification process, essential minerals also get removed. So, in order to retain essential minerals in water, TDS controller is added to the water purifiers like KENT Grand Plus, KENT Supreme and etc. The work of TDS controller is that it can retain the lost minerals in water and make it suitable for consumption.

  • Post Carbon filtration:

Post carbon filter comes as the final stage of RO filtration process and it removes volatile organic compounds (VOCs), taste and odor from water and make it 100% pure, safe and free from any kind of impurities.

Conclusion

So, if you are looking to purchase a water purifier for your home make sure that it has all the mentioned stages of water filtration process added to it.
