R.O. System

Reverse osmosis is a process that removes foreign contaminants, solid substances, large molecules and minerals from water by using pressure to push it through specialized membranes. It is a water purification system used to improve water for drinking, cooking and other important uses.

 How Does Reverses Osmosis (RO) Work?

As its name implies, RO takes osmosis, a natural process that occurs in every cell-based organism—plants, animals and even people—and reverses it.

 To understand reverse osmosis, you first need to know - what is osmosis? During regular osmosis, a diluted solution passes through a semipermeable membrane and flows into a more concentrated one. Example: When your fingers become “prune-y” after swimming in the ocean. Through osmosis, the water in our bodies passes through our skin, out to the water around us.

Now, here’s how reverse osmosis works:

Unlike osmosis, which is a passive process, reverse osmosis requires external force (pressure) to work.

Pressure is applied to a highly concentrated solute solution (e.g., salt water) to pass through a membrane to a lower concentrate solution.

The membrane allows water to flow through but blocks out larger molecules, like contaminants.

The reverse osmosis process leaves higher concentrations of solute (e.g., salt) on one side and only the solvent (e.g., fresh water) on the other.
