What is the difference between Osmosis and RO?

In reply to Dr. Nizam Uddin

Re: RO

by al jabir -
here,
Osmosis: some low concentration liquid (water) naturally flow into semipermeable membrane to high concentration liquid(salt solution), it's call be osmosis. and
Reverse osmosis: by pressurizing to more concentration liquid flow into passing the membrane for pure water, it's call be reverse osmosis.

Osmosis-Osmosis is a special case of diffusion in which the molecules are water and the concentration gradient occurs across a semipermeable membrane.
Reverse osmosis- It's occurs when the water is moved across the membrane against the concentration gradient, from lower concentration to higher concentration.

Osmosis is a special case of diffusion in which the molecules are water and the concentration gradient occurs across a semipermeable membrane. In reverse osmosis, pressure is exerted on the side with the concentrated solution to force the water molecules across the membrane to the fresh water side.

osmosis is the diffusion of water molecules from high to a lower water potential across a semipermeable membrane whereas the reverse osmosis is the diffusion of water molecules across a semipermeable membrane against the potential gradient

The main difference between osmosis and reverse osmosis is that the osmosis is the diffusion of water molecules from high to a lower water potential across a semipermeable membrane whereas the reverse osmosis is the diffusion of water molecules across a semipermeable membrane against the potential gradient

Osmosis involves :
1. No use of energy
2. Movement along the concentration gradient
3. Any semi permeable membrane
These two processes are the exact opposite to each other.
Reverse osmosis involves :
1. Use of energy
2. Movement against concentration gradient
3. Special dense membrane used.

 In reverse  osmosis pressure is exerted on the side with the concentrated solution to force the water molecules across the membrane to the fresh water side.

The different between osmosis and RO are as follows :-

Reverse osmosis involves :

1. Use of energy
2. Movement against concentration gradient
3. Special dense membrane used.

The main difference between osmosis and reverse osmosis is that the osmosis is the diffusion of water molecules from high to a lower water potential across a semipermeable membrane whereas the reverse osmosis is the diffusion of water molecules across a semipermeable membrane against the potential gradient. Furthermore, osmosis is a natural process while reverse osmosis is an artificial process.

Osmosis and reverse osmosis are two methods of water movement through a semipermeable membrane. The semipermeable membrane can be a type of biological or synthetic, polymeric membrane, which allows only certain molecules or ions to pass through it by diffusion.
