This video by Gary the Water Guy explains How a Reverse Osmosis System Works.
First a bit of history. Reverse Osmosis was first invented by the US Navy during World War II to be able to purify sea water into drinking water for use on submarines. So you know that it is particularly effective at removing sodium and other minerals in water, in fact up to 95% of the mineral content is removed!
A home reverse osmosis system is perfect for you if you are looking for an inexpensive source of "super pure" drinking water for your home. For a Reverse-Osmosis system to operate flawlessly the raw water needs to be pre treated to make sure there is no hydrogen sulphide, iron, manganese or hardness present which would quickly foul the membrane.
Your reverse osmosis system can be installed under the kitchen sink or in the basement.
A Reverse Osmosis system is connected to your cold water plumbing. The process starts out by passing your water through a Sediment Filter to remove particles in the water before going through a Carbon Filter to remove chemicals. Then the water is forced through a semi-permeable membrane which allows pure water to pass through it, while rejecting the contaminants that are too large to pass through the tiny pores in the membrane. As this water is being produced the membrane to continually cleaning itself, washing the rejected contaminants away from the membrane and down the drain.
Because Reverse Osmosis water is produced relatively slowly it needs to be stored in its own small pressure tank to make sure that there will plenty available for you.
A dedicated faucet is installed at the kitchen sink to dispense the Reverse Osmosis water and if you have a refrigerator with an ice maker and water dispenser the Reverse Osmosis system can be connected to it giving you cold "super pure" water as well as nice clear ice cubes which leave no residue when they melt in your glass.
