The process of removing dissolved ions, like salt, from brackish or seawater. Reverse Osmosis is a filtration process that will separate individual water molecules from an undrinkable feed water source like seawater. In the case of seawater desalination, high pressure is required (800+psi) to force individual water molecules through the Reverse Osmosis (RO) membrane while flushing salts, minerals, viruses, bacteria or any other contaminant down the drain. Using seawater or contaminated brackish feed sources, a properly designed RO system can provide pure, safe and great tasting water.
