Reverse-Osmosis-Filter-Membrane

How does the Reverse Osmosis Membrane Work?

A reverse osmosis membrane is a thin film with tiny pores that permit only water molecules to pass through, blocking all contaminants. It’s made of a semi-permeable material that allows water flow but blocks dissolved salts, organics, bacteria, and pyrogens. When pressurised, pure water diffuses through the membrane into the permeate flow, leaving contaminants behind. Reverse osmosis removes up to 99% of impurities.
Polluted water is forced through the semi-permeable membrane by mains pressure. Pure water passes easily, while pollutants larger than.0005 microns are washed away into a waste stream that goes down the drain. This waste stream contains all of the filtered-out contaminants, including pesticides, metals, bacteria, and viruses. Reverse Osmosis systems are consistently one of the better PFAS water filters and water filters that filters fluoride as well.
