Reverse Osmosis: What it is and How it Works

Reverse osmosis takes away contaminants from impure water with the help of a semipermeable barrier. Water will flow from a more concentrated area to a less concentrated area to supply clean water through osmosis.

A semipermeable barrier is composed of tiny pores that barricade contaminants yet still allowing water to pass through. In reverse osmosis, contaminants cannot enter the less concentrated part of the semipermeable membrane.

How Does It Work?

Reverse osmosis eliminates chlorine and sediment using a pre-filter before pushing water via a barrier to remove disintegrated solids.

After the water leaves the RO barrier, it goes through another filter to purify water before entering a faucet. RO systems undergo different stages depending on how many filters it comprises.

When water enters the system, it undergoes prefiltration, including a sediment and carbon filter to get rid of chlorine and sediment that could obstruct or impair the RO barrier. Then, water passes through the RO barrier, where microscopic particles are removed.

After the filtration process, water goes through the tank, and it is stored there until needed. Note that an RO system continually filters water unless full. Once you open the faucet, water leaves the tank and passes through another filter to make sure the water is safe and clean.

What are the Benefits of Reverse Osmosis?

An RO system is an extensive process of filtration. Why? That is because it gets rid of 98% dissolved solids, making water safe and healthy to drink. Unlike the RO method, using a distiller is less efficient even though it reduces TDS (Total Dissolved Solids).

Below are the benefits of Reverse Osmosis:

  • Reduces dissolved contaminants
  • Reduces sodium content
  • Eliminates odors and unpleasant tastes
  • Environment friendly
  • Easy to set up and maintain
  • Fits under a kitchen sink

With an RO system, your family is safe from drinking contaminated water.
