What is Reverse Osmosis?

Reverse Osmosis is a technology that is used to remove a large majority of contaminants from water by pushing the water under pressure through a semi-permeable membrane.

Reverse Osmosis is the process of Osmosis 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 but not the 

majority of dissolved 

salts, organics, bacteria and pyrogens. However, you need to 'push' the water through the reverse 

osmosis membrane by 

applying pressure that is greater than the naturally occurring osmotic pressure in order to desalinate 

(demineralize or deionize) water in the process, allowing pure water through while holding back a

 majority of 

contaminants.

How does Reverse Osmosis work?

Reverse Osmosis works by using a high pressure pump to increase the pressure on the salt side 

of the RO and force the water across the semi-permeable RO membrane, leaving almost all (around 95% 

to 99%) of dissolved salts behind in the 

reject stream. 

 

The amount of pressure required depends on the salt concentration of the feed water. The more 

concentrated the feed water, the more pressure is required to overcome the osmotic pressure.

The desalinated water that is demineralized or deionized, is called permeate (or product) water. The 

water stream that carries the concentrated contaminants that did not pass through the RO membrane

 is called the reject (or concentrate) stream.

 

As the feed water enters the RO membrane under pressure (enough pressure to overcome osmotic

 pressure) 

the water molecules pass through the semi-permeable membrane and the salts and other contaminants are 

not allowed to pass and are discharged

 through

 the reject stream (also known as the concentrate or brine stream), which goes to drain or can be fed 

back into

 the feed water supply in some circumstances to be recycled through the RO system to save water. 

The water

 that makes it through the RO membrane is called permeate or product water and usually has around 

95% to 99% of the dissolved salts removed from it.

What will Reverse Osmosis remove from water?

Reverse Osmosis is capable of removing up to 99%+ of the dissolved salts (ions), particles, colloids, 

organics, bacteria and pyrogens from the feed water (although an RO system should not be relied upon

 to remove 100% of bacteria&nb
