I assume this relates to desalination, right? A good overview of desalination techniques including reverse osmosis is given in IRC's TP40 Small Community Water Supplies - see the downloadable chapter

Hoi Jo,

Could you provide an updated link? This no longer works. Thanks!

Hi ,

In the absence of Jo's link, I hope the following helps:

Osmosis is the diffusion of a solvent or a dilute liquid through a skin( permeable in only one direction) into a more concentrated solution.

Reverse Osmosis is therefore the passage of a concentrated solution through a skin (permeable in only one direction) into a more dilute one.

It is a process widely used in water treatement, and pressures can be applied to improved process.
Please let us know what other info you require in the absence of a working weblink. Best wishes Pauline RedR
