Reverse Osmosis uses a semi-permeable
membrane to remove salts from potable/
brackish water. In Reverse Osmosis, water
pressure applied to the concentrated side
forces the process of osmosis into reverse.
Under enough pressure, treated water is
“squeezed” through the membrane from
the concentrated side to the diluted side.
