RO reverse osmosis
The reverse osmosis device separated from the pure water and solute-containing solution which
can only be semi-permeable membrane through water. At this time, the water of the pure water
side spontaneously passed a semipermeable membrane into the solution side ,and the solution side
of the water increased, this phenomenon is penetration. When the liquid level rises to a certain
height, the pressure on both sides of the membrane will reach equilibrium, the surface of the
solution side is no longer increased .At this time, the membrane on both sides will be a pressure
difference, which is called the osmotic pressure. If the solution side is coupled with a value greater
than the osmotic pressure, the water molecules in the solution will be squeezed to the pure water
side, this process coincided with the penetration of the opposite, which we call reverse osmosis.
We can see from the reverse osmosis process, due to the pressure, the water molecules in the
solution passed into pure water, pure water increases, while the solution is concentrated. The
reverse osmosis membrane is semipermeable, spiral wound membrane , when the raw water was
sent to the reverse osmosis membrane on a certain pressure, Through the small aperture of the
membrane, the water collected into pure water, impurities in the water, such as soluble solids,
organic matter, colloidal substances and bacteria, etc., will be intercepted by the reverse osmosis
membrane ,and be condensed and removed. in the closure liquid. A reverse osmosis can remove
more than 97% of the raw water solubility
