How Reverse Osmosis Water Filtration Systems Work

Posted by: Liam Mitchell -

Reverse osmosis is a filtration method driven by pressure that employs a partially permeable membrane to eliminate dissolved solids, organic substances, and microorganisms from water. The procedure functions by exerting pressure on the input water, compelling it to pass through the membrane while contaminants are retained and flushed away. In this article, we'll delve into the intricate workings of Reverse osmosis Water Filtration Systems and uncover how they bring you the quality water you deserve.

How Reverse Osmosis Water Filtration Systems Work

Before forcing water through a semipermeable membrane to remove dissolved solids, a Reverse osmosis System filters out sediment and chlorine with a prefilter. Before entering a special tap, drinking water is polished by a postfilter after leaving the RO membrane. Depending on how many pre filters and post filters are used, Reverse Osmosis Systems go through different stages.

Stages of Reverse Osmosis Water Filtration Systems

Pre-Filtration Stage

The pre-filtration stage is the foundation of every Reverse osmosis water filtration system. Water from your source, whether it be a well, a tap, or another supply, enters the system during this phase. A variety of filters are used to remove bigger impurities from the water, including sediment, chlorine, and rust. 

The Role of the Semi-Permeable Membrane

The semi-permeable membrane is the backbone of Reverse osmosis. Only water molecules can pass through the membrane's microscopic pores, which are designed to prevent the passage of contaminants and dissolved solids. Unwanted materials are removed as the water is forced through the membrane, leaving you with clean, clear water on the other side.

Pressurisation of Water

Pressure plays an essential role in driving water through the semi-permeable membrane. The system encourages water molecules to move through the membrane by applying significant pressure, while contaminants are left behind. This pressurised water, now devoid of impurities, continues on its path to becoming your pure drinking water.

Post-Filtration and Storage

After successfully passing through the membrane, the water goes through a post-filtration stage. Another set of filters is used in this phase to catch any remaining particles and ensure that the water is of the highest quality. The purified water is then stored in a designated tank and is ready for use whenever you need it.

Reverse Osmosis Systems benefits

Reverse osmosis systems are renowned for their thorough filtration capabilities, making them among the most comprehensive methods available. With an impressive 99% removal rate of dissolved solids, they significantly enhance the drinkability of water. 

  • Minimizes the presence of detrimental dissolved contaminants
  • Decreases sodium content
  • Eliminates unpleasant flavors and odors
  • Offers greater environmental sustainability compared to bottled water
  • Simple installation and upkeep
  • Designed to fit conveniently beneath kitchen sinks


RO is efficient in removing a wide range of contaminants and has a lower maintenance requirement, but it is energy-intensive and generates considerable wastewater. With the myriad of benefits they offer, choosing a Reverse Osmosis system is a step towards a healthier and more enjoyable life. So, why settle for anything less than the purest and most refreshing water at your fingertips? Choose a Reverse Osmosis water filtration system today to improve the quality of your water!
