Describe the processes of osmosis and reverse osmosis

 Processes of osmosis and reverse osmosis:

 

Osmosis: 

• Osmosis is the natural movement of water molecules from an area of high concentration to an area of low concentration through a selectively permeable membrane. 
• In osmosis, the water moves from a dilute solution to a more concentrated solution until the concentration of solutes is equal on both sides of the membrane.

Reverse Osmosis (RO):

•  Reverse osmosis is a process that uses pressure to reverse the natural flow of water in osmosis. 
• In reverse osmosis, water is forced through a semipermeable membrane that removes impurities and contaminants, producing a purified water stream.
