A reverse osmosis system improves the quality of drinking water, reduces several dissolved substances and gives water a better taste. Installed under the kitchen sink, it treats water in several stages before it reaches a dedicated faucet. At Wilfrid David in Chénéville, we install these systems and refill water jugs at our store. Here is what happens at each stage.
1. Incoming water
The system is connected to the home’s cold water supply, whether it comes from a municipal system or a well. This is the water that will be treated for drinking.
2. The prefilter
The prefilter holds back sediment, chlorine and impurities. Its job is to protect the membrane, the most important part of the system: water full of particles would wear it out much faster.
3. The reverse osmosis membrane
The membrane is an ultra-fine filter that only lets water molecules through. The water that passes through it, called permeate or RO water, continues on to the faucet.
The impurities held back by the membrane do not stay in the system. They are carried away by the reject water, also called concentrate, which goes down the drain through a connection on the sink drain. That is why every installation includes a drain connection.
4. The postfilter
Before reaching the faucet, the water goes through a postfilter that improves its taste and removes any remaining residue.
5. The faucet
RO water comes out of a faucet installed on the sink, next to the main faucet. Use it for drinking, cooking, making coffee or filling bottles.
With a well: have the water tested first
With a private well, water quality is the owner’s responsibility. Before choosing a treatment system, it is best to know what the water contains. The Government of Québec recommends having well water tested by an accredited laboratory at least twice a year for bacteria, and at least once for chemical contaminants. We arrange these tests with an accredited laboratory; all the details are on our Drinking water: sales and testing page.
