is method larger than osmotic pressure can reach to the objective of separation, extraction, purification and concentration.
The technology of reverse osmosis has many advantages while traditional water treatment methods dont have:
1. Reverse osmosis is to apply physical method of no phase-transition for desalination, purification in room temperature. Presently, the desalination rate of ultra thin composite membrane may be over 99.5％. Besides, it can also remove colloid, organic substance, bac
