The water is forced to flow across the membrane thereby leaving the impurities behind.


The compete RO water purification process explains the initial stage and that is when the raw water is passed through sediment filter that cleans all the solid dissolved particles present in the water. It is then passed through activated carbon filter where it effectively removes chlorine, volatile organic compounds (VOCs), taste and odor from water. It is then passed through the UV rays where the micro-organisms are deactivated/killed and the UF membrane stops the killed pathogens enter the filtered water. RO purifier removes essential mineral from the water during filtration, and to retain the minerals in the filtered water, TDS controller is added to the water purifiers. After this in the final stage, post-carbon filter is used to further purify the water and let you drink 100% clean and pure water.
