Reverse osmosis systems for purifying water have been around since 1977. At first, these were large volume industrial systems used by some municipal water purification plants. For a while now, domestic reverse osmosis units have become popular in our homes. They provide clean, healthy, great tasting water.
A reverse osmosis system has anything from 1 to 5 stages. Of course, a 5 stage reverse osmosis system is the best. They provide the greatest level of purification and some 5 stage reverse osmosis filter systems add essential minerals back into the water during the fifth stage.
To help you understand these water filters better, this article is going to discuss how a 5 stage reverse osmosis water filtration system works. All reverse osmosis filtration systems work on the same basic principles, it’s just the number of filtration levels that increase. So you were wondering what the difference is between 3, 4 and 5 stage reverse osmosis is, this is your answer. A 5 stage reverse osmosis system, uses 5 different types of filtration, a 4 stage system will use 4 and so on.
All reverse osmosis systems have common components. These would be a water inlet, filters, a pressurized storage tank, a drain (usually with an automatic shutoff valve), flow controller, check valve and finally, an outlet (usually a dedicated faucet at the kitchen sink).
Let’s look at how all these components come together in a 5 stage reverse osmosis filtration system and how they all work.
