osmosis The passage of water through a semi‐permeable
membrane, from a region of low concentration of solutes to one of higher concentration. Reverse osmosis is the passage of water from a more concentrated to a less concentrated solution through a semi‐permeable membrane by the application of pressure. Used for desalination of sea water, concentration of fruit juices, and processing of
whey. The membranes commonly used are cellulose acetate or polyamide of very small pore size, 10
−4−10
−3 μm. See also
