What is Reverse Osmosis and How Do Reverse Osmosis Plants ...

The currently emerging method which is gaining ground for producing fresh water form the sea water or brackish water is by the Reverse Osmosis (RO) process. In the RO process, water at high pressure passes through very fine membranes that allow only the water molecules to pass through. Plants basically consist of two phases. The first phase is a pre-treatment plant.
