2. What is RO (reverse osmosis)?

Reverse osmosis is the process of forcing a solvent from a region of high solute concentration

through a semipermeable membrane to a region of low solute concentration in the result of

applying an external pressure to reverse the natural flow of pure solvent. Then,the solute is

retained on the pressurized side of the membrane and the pure solvent is allowed to pass to

the other side. An effective membrane should not allow large molecules or ions through the

pores , but should allow smaller components of the solution (such as the solvent) to pass freely.

After processing through reverse osmosis membrane, most salts,organics, bacteria, heat source ,etc.contaminants are removed from water. Desalination rate can achieve up to 96%~98% and it

makes the water reach WHO potable water standard. It is also an appreciated water treatment processor to remove impurities from water in industry filed.

3. RO Water Treatment Applications

Beside potable water, a particular quality of water is required in a chemical, pharmaceutical,

nanotechnology, electronics, laboratory, and medical device process or other process application.
