Everything you need to know about RO - Pureit water India

A water purifier is one of the essential appliances that every Indian home must have. You need a dependable water filter to ensure that the water your family drinks is clean and healthy because the water that enters our homes includes microscopic contaminants. One of the best water purification technologies is Reverse Osmosis (RO), which provides water that is free of dangerous toxins.

Reverse osmosis, or RO, is a method of water filtration that may remove up to 99% of pollutants in water, including both visible and invisible particles. Typically, this is a multistage process that includes passing the water through a specific, semipermeable membrane. As a result, the water is cleaner and safer to drink, cook with, and utilise in other ways.

How does Reverse Osmosis work?

To comprehend the RO system, you must first know what osmosis is. A diluted solution flows across a semipermeable membrane and into a more concentrated solution to equalise the concentration on either side.

Osmosis occurs naturally. Roots of plants absorbing water from the earth are the best example of naturally occurring osmosis. Reverse Osmosis, on the other hand, is a system that works on the same concept as natural osmosis. However, in Reverse Osmosis, the water is not allowed to spontaneously permeate the semipermeable membrane. Under pressure, it is driven through the membrane.
The distinction between osmosis and Reverse Osmosis is that in the former, clean water goes towards polluted water while in the latter, clean water moves away from contaminated water. The model is turned on its head through Reverse Osmosis. It transports clean water from the contaminated side to the more clean side.

Domestic water is supplied under pressure; whether you live in a valley or a tower, this is how it arrives at your home. This pressure is used by Reverse Osmosis to drive water through a semipermeable membrane. 

When do you actually need a RO water purifier?

Whether you need a RO water purifier or not, that majorly depends on your water quality and the TDS (Total Dissolved Solids) level. TDS is made up of inorganic salts and trace amounts of organic substances that dissolve in water. TDS levels that are safe for the human body are less than 500 PPM.

Get your water tested to determine the TDS level in your drinking water. If you find out your drinking water has more than 500 ppm of TDS in the water, then you definitely go for an RO water purifier. 

As water is forced through the semipermeable membrane, impurities are left on the other side. This guarantees that the water that flows from your faucet is as pure as it possibly can be. Many RO systems use many filtering stages, often as many as seven, to make sure that the water they produce is as pure as possible.

Let’s get deep into what is RO:

Reverse Osmosis is a water filtering technology that can help remove undesired minerals, chemicals, compounds, and other pollutants in your drinking water. RO systems differ in function based on brand and design, but in general, they conduct the following tasks: pre-filtration, Reverse Osmosis, speciality filtering, drainage, and storage.


The procedure is utilised in the residential setting to provide households with clean water. People who want to be sure that the water they drink has undergone an additional level of filtration appreciate it.  


This was a detailed description of what RO is. Now let’s look at the water filtration phases that often occur in a Reverse Osmosis drinking water system listed below.

  • In the initial stage, a high-pressure pump is used to push feed water through the system, which is connected to drinking water pipes. Before entering the Reverse Osmosis chamber, feed water travels through several preliminary filters, including sediment and carbon filters. These early filters can take care of problems like rust, sand, and other bigger particles and bad tastes and odours caused by problems like chlorine.
  • To the human eye, this delicately constructed membrane appears to be virtually impermeable, acting as a barrier to pollutants. Only some contaminants can pass through the membrane when pressurized water is applied to it, and this depends on the texture of the membrane.
  • Some systems now include additional filtration stages to deal with impurities that the earlier stages couldn't handle on their own. 

The benefit of installing an RO

As mentioned above, Reverse Osmosis (RO) systems often use a multistage filtration process that also incorporates other filters in addition to the reverse osmosis kind of filtration. Reverse osmosis is a refined technique that uses high-pressure and special RO membranes to purify water. Features of RO water purifier that you should know: 

Provides Quality Service

RO systems are made up of several components, and as a result, some are more expensive than others. Cheaper versions frequently underperform over expensive and high-quality ones. They also last less than the more expensive purifiers. Avoid purchasing cheaper models and instead, search for the best RO water purifier in India to get the value for money. 

Powerful Filtration 

The water pressure is another factor that could impact the operation of RO systems. Water should be able to pass through the semipermeable barrier with enough pressure. If there is insufficient pressure, the water can be directed straight to the drain. In these circumstances, installing a separate water pressure pump to raise the water pressure at the installation place is usually necessary. While water passes through a membrane under pressure, the pressure is controlled so that all pollutants are captured. 
Sediment Filter

Water first flows through sediment treatment, where large particles are removed from the water, before passing through the semipermeable membrane. Large debris, dirt, rust, and salt are the substances taken out at this stage.

Carbon Filtration

Impurities that could harm the semipermeable membrane are eliminated at this stage. Chlorine, insecticides, and other microscopic particles that can pass through the semipermeable barrier are among these contaminants. One benefit of carbon filters is that they improve the taste of the water, which is one of the main benefits of RO systems.

RO Membrane

The water can travel through the semi-permeable membrane because it often contains no particles or big sediments at this point. When water is forced toward this membrane, it can pass through the countless microscopic pores that it contains. This indicates that this membrane can only let clean water pass through.

Water TDS Level

The residential RO water purifiers might not function if the input water has significant amounts of impurities (TDS is more than 2500 ppm). You might need to install commercial RO systems in such circumstances. Similarly, employing a RO water purifier would reduce the TDS of filtered water significantly lower than the ideal TDS in drinking water if the TDS of the input water is under 300 ppm. In these circumstances, you want to buy the greatest RO + UV water purifier India has to offer.

These were the features that should be in best-in-class RO systems. Now if you are at the starting point of getting the finest water purifier for your home then here are some of the informative RO water purifier suggestions for you to look at
