Reverse Osmosis is the method of removing the contaminants such as many unwanted large molecules and ions from the unfiltered water by applying pressure through a semipermeable membrane. It is interesting to know how reverse osmosis works. It is commonly known as RO. The freshwater which is then obtained is called as permeate, and the concentrated leftover is termed as brine.

A lot of time, people stay confused about how does an RO system work as they want to understand whether it is worth investing in a water filtration system. Let us talk about it further. But before moving ahead, let us tell you what a reverse osmosis system is capable of removing.

An RO Water Filtration System Is Capable Of Removing:

  • Fluoride
  • Salt
  • Sediment
  • Chlorine
  • Arsenic
  • VOCs
  • Herbicides and pesticides

How Does A Reverse Osmosis System Work?

The main function of an RO system is to remove sediments and chlorine from the water with the help of a pre-filter before applying pressure on it to make it pass through split membrane which finally removes the dissolved solid leftovers. Once water leaves the RO membrane, it then again passes through another filter to get water polished before entering the main faucet. This makes reverse osmosis water filtration system useful for day-to-day life.

Stages Involved In Reverse Osmosis; How It Works

Reverse osmosis system takes care that the water is clean and free from unwanted contaminants. Hence, it involves 4 main stages before the water is ready for consuming or other household needs. These are:

  1. Sediment Pre-Filter
  2. Carbon Pre-Filter
  3. Reverse Osmosis Membrane
  4. Post Carbon Filter

Once all the steps are completed, your filtered water is ready to use.

Benefits Of Reverse Osmosis System

An RO system is capable of removing 98% of dissolved solids that make water hard and impure. Since we have discussed how does reverse osmosis water filter work, let us now look at the benefits of installing RO.

  • A reduction in the percentage of dissolved harmful contaminants in water.
  • It reduces the quantity of sodium from the water.
  • It helps in dealing with the foul odour of water and its bad taste.
  • Installation and maintenance are relatively easy.
  • It is a better option than buying water bottles from the market and also beneficial for the environment, since less plastic.
  • It can easily be installed under the sink.
