Basics of Reverse Osmosis - puretecwater.com
puretecwater.comReverse Osmosis is the process of Osmosi s in reverse. Whereas Osmosis occurs naturally without energy required, to reverse the process of osmosis you need to apply energy to the more saline solution. A reverse osmosis membrane is a semi ---permeable membrane that allows the passage of water molecules
