ERI Pressure Exchanger
energy recovery system

Appoximately 60 bar are necessary for sea water desalination with reverse osmosis. The water leaves the membranes with a remaining pressure of 58 bar. The ERI system recovers 93 to 97% of this energy and makes sea water reverse osmois plants affordable.
