Reverse Osmosis is a filtration technique that forces water through a membrane, leaving any contaminants behind
Reverse Osmosis is a filtration technique - one of the most popular, with the best filtration methods. Reverse Osmosis works as water is forces across a semi-permeable membrane, leaving contaminants behind that are flushed down the drain. The clean drinking water collects in a holding tank.
The Reverse Osmosis water purification process is a simple and straightforward filtration process. It is accomplished by water pressure pushing tap water through a semipermeable membrane to remove impurities from water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure (a colligative property) that is driven by chemical potential differences of solvent.
