How Do Reverse Osmosis Filters Work? (Breakdown of Process)

The partially permeable RO membrane is made of a thin-film composite and can be expected to remove up to 98% of total dissolved solids (TDS) down to 0.001 microns. This is the key part of the reverse osmosis filtration process and the element which sets it apart from other filtration systems. 4. Storage.
