What does RO water purifier do to water

RO Purifier

Nowadays, city water, well water or water from tankers may not be available in its pure drinking form. Most often the water is contaminated with harmful pollutants that cause water unfit for drinking, without purifying it. Moreover, drinking polluted water can lead to diarrhea, typhoid, and several other ailments.

The only optimum solution to this is to use the RO filter system that purifies water by passing through many layers of filtration.

The filtration process involves pre-filtration, then it passes through reverse osmosis membrane, UV lamp, ultrafiltration, and lastly through post-filtration. For sure, it would be interesting for you to know how your domestic RO plant works.

So, let’s understand it in detail.

Working process of domestic water purifier

Reverse osmosis as the name goes by the process works in a reverse way. Here only the water molecules pass through the semipermeable membrane flushing out the contaminants from the system.

Pre-filtration: This filter does the work of RO membrane-less troubled by removing more abundant sediments, salts, and chlorine. This process is carried out using a sediment filter or carbon block filter, which is the first cartridge in the system.

The filter protects the RO membrane by filtering out larger particles, which could otherwise get clogged and damage the membrane. Also, excess chlorine can have adverse effects on the membrane.

You need to know in RO purifying system; it works best with soft water. So, if you have access to hard water, then it is highly recommended to install a water softener or choose a variant that is suitable for your water type.

The scaling formed from hard water can affect the RO system like how it does to your appliances. To keep your water purifier safe must connect with Kent RO Service and enjoy their hassle-free service.

Reverse Osmosis Membrane

The pressurized water is forced through a synthetic plastic material, which traps viruses, bacteria, chlorine, calcium, urea, and other large molecules. To give you an idea of the strength of the RO membrane, it is the size of one human hair, which is around 100 microns wide.

RO membrane also helps in removing copper, cadmium, barium, lead, nitrates and nitrites, arsenic, selenium, chromium, fluoride, cryptosporidium, and total dissolved salts.

UV lamp

The UV lamp in RO Water Purifier destroys harmful microorganisms. The UV rays directly attack their genetic core to kill them at source and put an end to their reproductive cycle. The most potent and commendable job of the UV lamp is to disinfect 99.99 percent of pathogens present in water, thereby rendering safe water to drink.


The other component in the RO water purifier is ultrafiltration. Here the water is forced to pass through a hollow fiber membrane trapping all the impurities and leaving you with clean and pure water.

Post filtration

Before water reaches your storage tank, it passes through a carbon filter to remove any contaminants that missed passing through the filters. Then, it stores in your storage tank until you use it.

The final round of filtration includes one last polishing of your water, where water passes through an in-line activated carbon filter to remove any odor or foul taste. And now, at last, the water is fit for consumption.

So, water purifier although it looks to be one compact unit and seems easy to filter to one’s eyes it isn’t. It plays a vital role to make sure you drink pollutant-free water.
