In a world where clean and safe drinking is becoming scarce, purification through reverse osmosis is becoming increasingly popular. Thanks to the latest technology which is highly effective to cleanse all the contamination. However, have you considered knowing the way your RO water filter works? You will be shocked to know that the intricate mechanism that intuitively works in this read.

The Basic Mechanism

In RO filtration processes, the pollutants and contaminants are to be removed from the water by forcing it through a semipermeable membrane. You must remember to replace the membrane after every one or two years. This ensures the optimum performance enhances longevity.

Key Components of RO System

RO filtration system is a combination of various systems performing altogether. Keep reading to learn about the key components.

The Pre-Filtration

Before the water enters the RO membrane, it passes through various prefilters. These prefilters help remove a large number of impurities from the water. A few are sand, chlorine, sediments, and much more, which could clog the membrane if entered. Prefilters work more like a membrane protective agent and further enhance the osmosis processes.

At the time, you will need to clean the prefilters, and for that, taking professional help is the best. You may type RO service near me in Patna on your phone to get in touch with RO Care India, the one-stop solution to all of your RO filter issues.

The RO Membrane

The semipermeable RO membrane is the main functioning unit of any system for reverse osmosis. The design is basically the science of letting water molecules pass through while preventing most pollutants and impurities. After that, pure and filtered water and concentrated brine are successfully separated using a combination of microscopic holes and a molecular size cut-off.

The Pressure Pump

RO filters usually require a certain water pressure to complete filtration. In case you don’t have a water source with at least 40-60 PSI, you might need to install a pressure pump. In order to force water molecules through the membrane’s tiny pores and drive impurities aside, installing a pressure pump is a must.


Once the water passes through the RO membrane, it undergoes yet another round of filtration. This method is called the post-filtration. It is typically a process that involves carbon filtration, which helps improve the taste and remove any Odour from the water.

The Way RO Filter Removes Contaminants

Reverse osmosis water filters eliminate a wide variety of impurities from drinking water because of their excellent efficacy. Here is how RO filters function to get rid of typical impurities.

Removing Suspended Solids

The prefilters work as a gate to the RO membrane; they remove any suspended metals in the water. The prefilters effectively remove any solid particles like sand, rust, sediments, or anything that can clog the membrane.

Removes Dissolved Solids

The RO membrane has the ballistic capability to remove any dissolved solids from the water. Any substance which is larger in molecular size, like salt and other heavy metals, makes no entry through the membrane.

Removes Bacteria and Viruses

While not al RO membranes cannot remove bacteria and viruses, a few models can. Those RO purifiers, which come with small membrane pores compared to others, can effectively separate bacteria and viruses. As per the expert’s suggestion, getting an RO system that removes all sorts of foreign impurities is the best thing you can do.

Separates chlorine and other compounds

The removal of chlorine, volatile organic compounds (VOCs), and other organic pollutants is a key function of carbon post-filters in RO systems. These filters improve the taste and smell of the water by using adsorption to catch these impurities.

Removal of Total Dissolved Solids

TDS (Total Dissolved Solids) level in water reduces after the filtration through Reverse Osmosis processes. This is one reason doctors these days promote drinking RO-purified water.

The Conclusion

Reverse osmosis is a potent water filtration method that uses the natural osmosis process but in the opposite direction to eliminate impurities from water. RO systems may successfully remove suspended particles, dissolved solids, bacteria, viruses, and different chemicals utilising a semipermeable membrane. Also, you must remember to contact a qualified water purifier service in Patna for a periodic checkup.
