What’s Inside the Reverse Osmosis Filter

Water Filters

The reverse osmosis filter system has been an effective and reliable method of water filtration that’s often added on top of the sediment and carbon filters. The result is a much cleaner and purer water that’s often appreciated that it has become a standard for any water filtration.

A reverse osmosis system relies on its membrane that’s made of three fine layers that’s rolled into a cylinder. These three layers act as both a barrier and a passage through which water passes, leaving some of its impurities in the sheet.

The sheet has a polyester support base on which the polysulfone layer is sits. Then, its polyamide outer layer acts as a barrier. It acts as its firm barrier that’s just 0.2 microns thick. This polyamide layer keeps chemicals, viruses and bacteria from going through.

The permeable sheet is layered with a feed channel spacer sheet that purposely causes turbulence as the water passes through.

Layers of permeable sheet and spacer are sandwiched to make one membrane that allows water through more easily for filtration to occur. This sandwiched membrane is then rolled into a tube where water is forced through by pressure.

Water goes through the spacer and the rolled membrane where it eventually collects in the core tube. This water is what goes out as the final filtered result of the reverse osmosis filter system.
