Reverse osmosis process

Reverse osmosis (RO) is a process that is commonly employed for desalination of seawater. RO systems leverage asemi-permeable membrane to remove ions, molecules and unwanted contaminants and particles (salt in the case of desalination) from water. In a u-tube with unsalinated water on one side, salinated water on the other side, separated by a semi-permeable …
