Have you ever wondered how a reverse osmosis (RO) system filters your drinking water? This process takes place through several simple steps. Each one removes certain particles from water, leaving it clearer and better tasting.
In this article, we will go through how it works in a straightforward way.
Starting with the pre-filtration stage:
Before the water reaches the main part of the reverse osmosis UAE system, it goes through one or more pre-filters. These filters trap larger particles such as dirt, rust, and sand. In many systems, this stage also reduces chlorine, which can affect the next part of the system. This step prepares the water for the reverse osmosis membrane.
The reverse osmosis membrane:
This is the centre of the RO system. The membrane is a thin layer with tiny holes. These holes are small enough to stop many types of dissolved solids and other unwanted particles from passing through. Water is pushed through this membrane with pressure, and the clean part moves forward while the rest is separated out.
Post-filtration for better taste:
After going through the membrane, the water may pass through another filter—often a carbon filter. This final stage improves the taste and smell by removing any leftover particles that might affect the water’s flavour. It adds a finishing touch before the water goes into the storage tank.
Storage tank and delivery:
Clean water is stored in a small tank that is ready to be used when necessary. Once the tap is turned on, water flows out from the tank and through one last small filter, if fitted, for an extra polish before it reaches your glass.
Handling the wastewater:
As part of the process, the RO system also creates a stream of water that carries away the unwanted particles. This is called reject water or brine. It goes down the drain while the filtered water is stored. This separation is how the system keeps the clean and used water apart.
Regular filter checks:
For the RO system to keep working smoothly, the filters and membrane want to stay clean. Over time, they catch more and more particles, which can reduce how much water passes through. Looking at the filters from time to time and changing them when necessary supports better water flow and taste.
