A reverse osmosis plant is a manufacturing plant where the process of reverse osmosis takes place. Reverse osmosis is a common process to purify or desalinate contaminated water by forcing water through a membrane. Water produced by reverse osmosis may be used for a variety of purposes, including desalination, wastewater treatment ...

RO production train, North Cape Coral Reverse Osmosis Plant. In 1977 Cape Coral, Florida became the first US municipality to use RO at scale, with an initial operating capacity of 11.35 million liters (3 million US gal) per day. By 1985, rapid growth led the city to operate the world's largest low-pressure RO plant, producing 56.8 million ...

[2] [3] Richard Norman submitted a manuscript describing the concept to Science in May 1974. [4] In that manuscript, Norman clearly indicated that he was unaware of any prior work on the topic. Loeb submitted a comment on Norman's cost analysis to Science in January 1975. [5] In that publication, Loeb proposed the term "pressure retarded osmosis".

The first edition of the ICNCP, which was agreed in 1952 in Wageningen and published in 1953, has been followed by seven subsequent editions – in 1958 , 1961 (update of 1958), 1969 , 1980 , 1995 , 2004 and 2009 . [4] The ninth (most recent) edition was published in 2016 . [5]
In contrast, the reverse osmosis process uses hydraulic pressure as the driving force for separation, which serves to counteract the osmotic pressure gradient that would otherwise favor water flux from the permeate to the feed. Hence significantly more energy is required for reverse osmosis compared to forward osmosis.
