Reverse Osmosis membrane water filter consists of several thin layers or sheets of film that are bonded together and rolled in a spiral configuration around a plastic tube, also known as a thin film composite or TFC membrane.
The material of the membrane is semipermeable: it allows water molecules to pass through while acting as a barrier to dissolved solids (i.e.: mineral chemical contaminants).
When the feed water stream passes across the surface of the membrane, the molecules penetrate the membrane surface, working their way around the spiral and collecting in the center tube. The remaining contaminants are concentrated and washed from the surface of the membrane down the drain.
How long will a membrane last?
In general a membrane will last about 2 years, especially if regularly flushed. The best way to test the membrane is using a TDS meter to determine if the quality of the water has deteriorated.
