Reverse osmosis

With reverse osmosis you can have the purest water flowing out of your tap. On this page we explain how this process works and for which substances you can use it.

What is reverse osmosis?

Reverse osmosis is a method to filter water and remove unwanted substances. A membrane is used that allows water to pass through, but blocks other substances. The great advantage of reverse osmosis is that no chemicals are needed to purify the water: the membrane filter does all the work.

How does reverse osmosis work?

Reverse osmosis uses the natural process of osmosis to produce pure water. To understand how reverse osmosis works, it’s useful to first know what osmosis is.

Imagine a container with water. In the middle of that container, you place a special semi-permeable membrane filter (‘semipermeable wall’), which divides the tank of water into two equal pieces. A semipermeable membrane allows water to pass through, but blocks other (larger) particles, such as salt. If you add one tablespoon of salt to one side of the container and three tablespoons of salt to the other side, you will notice water flowing through the membrane from one side (with little salt) to the other side (with a lot of salt). This process stops when the concentration of salt in both parts of the container is the same, or when the pressure of the water on the side that contains a lot of salt becomes so high that no more water can enter.

Reverse osmosis uses that second principle. By applying extra pressure to the water that contains a lot of salt, water flows to the other side through the membrane. But the salt cannot pass through the membrane. Only pure water flows to the other side of the membrane. By continuously exerting pressure on one side, pure water continues to flow to the other side.

For which substances can you use a reverse osmosis system?

Above we have explained how reverse osmosis worked, using the example of a container filled with water to which you add salt. But a semipermeable membrane blocks many more substances. Examples are:

Reverse osmosis is thus an ideal method to obtain very pure water. For instance, this is necessary if you work in a laboratory. But did you know that your tap water can also contain all of the above substances? Not really a pleasant thought, that by simply drinking a glass of tap water all kinds of foreign, possibly harmful substances enter your body. Fortunately, reverse osmosis can also be used at home. This way you can enjoy in your own home all the best that water has to offer.
