توضیحات:
Reverse Osmosis is a process that is used to remove a wide range of salts to give water of a high purity. Osmosis is a natural processinvolv ing fluid flow across a semi-permeable membrane barrier.It is the process by which nutrients feed the cells in our bodies and how water gets to the leaves at the top of trees.
If you separate a solution of salts from pure water using a basic thin semi-permeable membrane like a sausage skin, the pure water passes through the membrane and tries to dilute the salt solution. If the salt solution is connected to a vertical pipe then the progressively diluted solution will fill the pipe until the ‘osmotic pressure’ drawing the pure water though the membrane is the same as the head pressure of the diluted solution
This process can be reversed – hence ‘Reverse Osmosis’ – by applying a higher pressure to the salt solution. Pure water will then pass the through the membrane in a process that is easy to visualise as ‘filtration’ where the filter will only let through the small water molecules and retain almost all of the other molecules.This means that water containing a high level of natural salts can be purified without the need for chemical regenerants such as the acid and caustic used in demin plants.
Reverse Osmosis is therefore considered a much safer route of producing pure water for many commercial and industrial applications.In addition the plant does not need to be taken out of service for regeneration as a demin plant does.
